    Intended Use

    The Apollo TMS Therapy System is indicated for the treatment of Major Depressive Disorder in adult patients who have failed to achieve satisfactory improvement from prior antidepressant medication in the current episode, as well as an adjunct for the treatment of adult patients suffering from Obsessive-Compulsive Disorder (OCD).

    Device Description

    The Apollo TMS Therapy System is an electromagnetic device that non-invasively delivers a rapidly pulsed magnetic field to the cerebral cortex in order to activate neurons within a limited volume without inducing a seizure. This method of cortical stimulation by application of brief magnetic pulses to the head is known as Transcranial Magnetic Stimulation (TMS).

    The Apollo TMS Therapy System is comprised of the following principal components:

    • User Interface
    • Main Unit (with or without housing)
    • Stimulation Coil
    • Coil Positioning System

    The operator controls the Apollo TMS Therapy System via the user interface (application software "Stimware"). "Stimware" is a treatment and data management software that administrates treatment protocols and the patient´s individual stimulation dose determined by the patient´s individual motor threshold. Stimulation is applied via the stimulation coil. For the treatment of major depressive disorder, the stimulation coil is positioned to the left dorsolateral prefrontal cortex (DLPFC) by means of the coil positioning system. The observed and documented increase in cortical excitability after high frequency rTMS has been shown to persist beyond the duration of the train of stimulation. For treatment of OCD, the stimulation coil is positioned to the dorsomedial prefrontal cortex (DMPFC).

    AI/ML Overview

    The provided FDA 510(k) clearance letter and summary for the Apollo TMS Therapy System (K243539) indicate that the device is substantially equivalent to predicate devices. This clearance is based on non-clinical performance data and a comparison to existing cleared devices rather than a de novo clinical comparative effectiveness study.

    Here's an analysis of the acceptance criteria and the study that proves the device meets them, based on the provided text:

    1. Table of Acceptance Criteria and Reported Device Performance

    The acceptance criteria for this 510(k) submission are primarily based on demonstrating substantial equivalence to existing legally marketed predicate devices, particularly for the extended indication of Obsessive-Compulsive Disorder (OCD) treatment. The criteria are therefore focused on matching or being demonstrably similar to the predicate device's performance, especially for the OCD treatment parameters, and adhering to recognized safety and performance standards.

    Acceptance Criteria (Inferred from 510(k) Summary)Reported Device Performance (Apollo TMS Therapy System K243539)
    Intended Use Equivalence: Identical intended use as predicate devices.The Apollo TMS Therapy System is indicated for the treatment of Major Depressive Disorder in adult patients who have failed to achieve satisfactory improvement from prior antidepressant medication in the current episode, as well as an adjunct for the treatment of adult patients suffering from Obsessive-Compulsive Disorder (OCD). This matches the intended use of the primary predicate device (HORIZON® 3.0 TMS Therapy System K222171) for OCD, and the secondary predicate (Apollo TMS Therapy System K232639) for MDD.
    OCD Treatment Stimulation Parameters Equivalence: Identical brain area, intensity (100% leg MT), frequency (20 Hz), pulse train duration (2 sec), inter-train interval (20 sec), trains per session (50), max no. of pulses (2000), and treatment schedule (5 daily sessions for 5 weeks, 4 daily sessions for 1 week) as the primary predicate device.Area of brain to be stimulated: DMPFC (Identical to predicate)

    Software Life Cycle Processes: Conformance to IEC 62304 and FDA guidance for software.Software verification and validation testing conducted and documented in accordance with IEC 62304 and internal quality procedures. Software documentation considered "basic documentation" (supported by Special Controls Guidance "rTMS Class II").
    Risk Management: Application of ISO 14971 and IEC 62304 throughout the product development lifecycle with no new hazards/harms compared to predicates.Risk assessment applied. Results indicate no new hazards, harms, or safety risks introduced when compared to the predicate devices.
    Output Stimulation Parameters: Adequately similar output stimulation parameters (amplitude, pulse width, frequency, pulse train duration, ITI range, max # of pulses per session) to enable substantial equivalence determination.Detailed comparison provided in the summary. While pulse width differs, the output stimulation is considered "adequately similar" to the primary predicate for OCD treatment. Other parameters within acceptable ranges or directly comparable.
    Stimulation Coil Parameters: Similar coil configuration (figure-of-eight), output waveform (biphasic), E-Field at 1.0 SMT (130 V/m).All identical to predicates.
    Coil Positioning System: Comparable in function and method to predicate devices.Integrated into Head-and-Neck-Support System (HANS), Landmark-Aided Coil Placement, TMS Cap for standardized 10-20-EEG Positioning with Coil Positioning Arm. Considered comparable or improved over predicate.

    2. Sample size used for the test set and the data provenance

    The submission does not detail a specific "test set" sample size with patient data for efficacy, as it claims substantial equivalence primarily through non-clinical performance testing and direct comparison of specifications and treatment parameters to already cleared devices.

    The "study" relies on:

    • Non-clinical performance testing: This would involve engineering and laboratory testing for electrical safety, EMC, usability, temperature, and stimulation intensity, rather than a sample size of patients.
    • Leveraged data from prior clearances (K180313 and K232639): This indicates that data from previously cleared versions of the Apollo TMS Therapy System was used as a basis.
    • Primary predicate device (HORIZON® 3.0 TMS Therapy System K222171): The effectiveness of the OCD treatment protocol is derived from the established effectiveness of this predicate device, which was itself cleared based on its own clinical or non-clinical data.

    Data Provenance: Not specified in terms of country of origin or retrospective/prospective for patient data, as direct clinical effectiveness data for the subject device was not required for this 510(k) clearance due to the substantial equivalence claim. The non-clinical testing would have been conducted by the manufacturer (MAG & More GmbH, Germany).

    3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts

    This information is not applicable as the submission does not describe a clinical study where experts established ground truth for a test set of patient data. The clearance is based on comparison to a predicate device and non-clinical engineering tests.

    4. Adjudication method for the test set

    This information is not applicable as there was no clinical test set requiring expert adjudication.

    5. If a multi reader multi case (MRMC) comparative effectiveness study was done, If so, what was the effect size of how much human readers improve with AI vs without AI assistance

    This information is not applicable. The Apollo TMS Therapy System is a therapeutic device that directly applies magnetic stimulation, not an imaging analysis or diagnostic AI device that involves "human readers" or AI assistance in interpretation. No MRMC study was conducted or mentioned.

    6. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done

    This information is not applicable in the context of an "algorithm only" performance study. The Apollo TMS Therapy System is a hardware device with controlling software. Its performance is always "standalone" in the sense that the device itself (hardware+software) delivers the therapy; there isn't a separate "human-in-the-loop" performance associated with its direct therapeutic action, but rather clinical oversight and operation by a healthcare professional. The software verification and validation are noted, but this is for the control system's reliability, not an "algorithm-only performance" in the diagnostic AI sense.

    7. The type of ground truth used

    For the effectiveness of the OCD treatment, the "ground truth" is essentially the established clinical efficacy of the primary predicate device (HORIZON® 3.0 TMS Therapy System K222171), whose OCD treatment protocol the Apollo TMS Therapy System replicates. The substantial equivalence claim means that because the subject device's treatment parameters are identical and its output stimulation is adequately similar, it can be expected to achieve the same therapeutic effect.

    For the safety and performance of the device itself (e.g., electrical safety, temperature limits, consistent stimulus delivery), the "ground truth" is established through adherence to recognized consensus standards (e.g., IEC 60601-1) and successful non-clinical engineering tests.

    8. The sample size for the training set

    This information is not applicable. The Apollo TMS Therapy System is not an AI/ML device in the sense of requiring a large "training set" of patient data for its primary function. Its software (Stimware) manages protocols and patient data, but it's not "trained" on patient outcomes to learn or adapt therapeutic delivery in an AI sense.

    9. How the ground truth for the training set was established

    This information is not applicable for the same reasons as point 8.

    Intended Use

    Rapid2 Magnetic Stimulators (Magstim Rapid2, Magstim Super Rapid2, Magstim Super Rapid2 Plus1) are intended to stimulate peripheral nerves for relief of chronic intractable, post-traumatic and post-surgical pain for patients 18 years or older.

    Device Description

    The Magstim Rapid2, Magstim Super Rapid2, Magstim Super Rapid2 Plus1 (herein collectively referred to as "Rapid2 Magnetic Stimulators") are computerized, electromechanical medical devices that provide brief and focused magnetic pulses in order to non-invasively stimulate peripheral nerves for relief of chronic intractable, post-traumatic and post-surgical pain for patients 18 years or older. The subject device is intended to be used in hospitals and clinics such as pain management clinics.

    Rapid2 Magnetic Stimulators are integrated systems consisting of a combination of hardware, software, and accessories. Rapid2 Magnetic Stimulators are offered in multiple configurations:

    • Rapid2
    • Super Rapid2
    • Super Rapid2 Plus1

    All three configurations have identical intended use/indications for use, common specifications, equivalent performance characteristics and equivalent composition to each other. Specifically, Rapid2 and Super Rapid2 have received prior clearance under K051864 for Peripheral Nerve Stimulation (Product Code: GWF, Regulation 21 CFR 882.1870). All Rapid2 Magnetic Stimulators are made up of components that have received prior clearance under K051864 (e.g., the 3190-00, 3192-00 and 3193-00 coils) and components which have received prior clearance under K051864 but have received modifications due to aspects like obsolescence (Mainframe, Power Supply etc.).

    All Rapid2 Magnetic Stimulators are composed from the following main components:

    • Stimulating Unit & Power Supply
    • User Interface
    • Stimulating Coil
    • System and Stimulating Coil Cart and Holding Arm

    Rapid2 Magnetic Stimulators include temperature monitoring via two independent temperature sensors to ensure surfaces of the coils do not reach unacceptable levels. The cut-off is set to act at 40°C at which point the system will automatically be disabled. Over-temperature conditions are also communicated on the User Interface (UI) via a temperature gauge and alarm system. Rapid2 Magnetic Stimulators also includes the 3910-00 air-cooled coil to further mitigate any temperature conditions. The 3910-00 air-cooled coil comes with all 3 configurations (Rapid2, Super Rapid2 and Super Rapid2 Plus1) as standard.

    AI/ML Overview

    The provided document is an FDA 510(k) Clearance Letter for the Rapid2 Magnetic Stimulators. It does NOT contain information about a study proving the device meets acceptance criteria related to its performance in pain relief. Instead, it focuses on demonstrating substantial equivalence to a predicate device through non-clinical testing of technical characteristics, safety standards compliance, and physical properties.

    The document does not describe an AI/ML-driven device, nor does it present results from a clinical study with patients or human readers using AI. The acceptance criteria and performance metrics described are related to physical and electrical characteristics of the magnetic stimulator, not diagnostic accuracy or clinical effectiveness in a traditional sense of "performance" as one might expect for an AI diagnostic device.

    Therefore, many of the requested items (e.g., sample size for test/training sets, data provenance, number of experts for ground truth, MRMC study, standalone performance, ground truth type) cannot be answered based on the provided text, as they pertain to clinical or AI/ML performance evaluation, which is not the subject of this 510(k) summary.

    However, I can extract information related to the technical acceptance criteria and how they align with the device's measured performance as described in the summary:


    Acceptance Criteria and Device Performance (Based on Technical and Safety Equivalence)

    Regarding the specific questions that cannot be answered from the provided text:

    1. Sample sizes used for the test set and the data provenance: Not applicable or provided. The "test set" here refers to non-clinical testing of device characteristics, not a clinical study on patients or data.
    2. Number of experts used to establish the ground truth for the test set and the qualifications of those experts: Not applicable or provided. Ground truth in this context would implicitly be engineering specifications, laboratory measurements, and standard compliance testing, not expert clinical assessment of patient data.
    3. Adjudication method (e.g. 2+1, 3+1, none) for the test set: Not applicable or provided. No adjudication process detailed for establishing technical specifications.
    4. If a multi-reader multi-case (MRMC) comparative effectiveness study was done, If so, what was the effect size of how much human readers improve with AI vs without AI assistance: Not applicable. This is not an AI/ML device, nor is it a diagnostic device being evaluated for reader performance.
    5. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done: Not applicable. Not an AI/ML algorithm.
    6. The type of ground truth used (expert consensus, pathology, outcomes data, etc.): The "ground truth" for this device's performance evaluation is based on engineering specifications, direct physical measurements (e.g., of magnetic fields, temperatures, electrical properties), and compliance with international safety and performance standards (e.g., IEC 60601 series, ISO 10993).
    7. The sample size for the training set: Not applicable or provided. This device does not use a "training set" in the machine learning sense.
    8. How the ground truth for the training set was established: Not applicable or provided.

    In summary, the provided document details the 510(k) clearance process for a non-AI/ML magnetic stimulator for pain relief. The "acceptance criteria" and "performance" are framed around demonstrating substantial technical and safety equivalence to a legally marketed predicate device, rather than clinical efficacy data from patient studies or AI algorithm performance metrics.

    Intended Use

    The MAGNETOM system is indicated for use as a magnetic resonance diagnostic device (MRDD) that produces transverse, sagittal, coronal and oblique cross-sectional images, spectroscopic images and/or spectra, and that displays, depending on optional local coils that have been configured with the system, the internal structure and/or function of the head, body, or extremities. Other physical parameters derived from the images and/or spectra may also be produced. Depending on the region of interest, contrast agents may be used. These images and/or spectra and the physical parameters derived from the images and/or spectra when interpreted by a trained physician yield information that may assist in diagnosis.

    The MAGNETOM system may also be used for imaging during interventional procedures when performed with MR compatible devices such as in-room displays and MR Safe biopsy needles.

    Device Description

    AI/ML Overview

    The provided 510(k) clearance letter and summary describe the acceptance criteria and supporting studies for the MAGNETOM Flow.Ace and MAGNETOM Flow.Plus devices, particularly focusing on their AI features: Deep Resolve Boost, Deep Resolve Sharp, and Deep Resolve Swift Brain.

    Here's a breakdown of the requested information:

    1. Table of Acceptance Criteria and Reported Device Performance

    The document uses quality metrics like PSNR, SSIM, and NMSE as indicators of performance and implicitly as acceptance criteria. Visual inspection and clinical evaluations are also mentioned.

    FeatureQuality Metrics (Acceptance Criteria)Reported Performance (Summary)
    Deep Resolve BoostPeak Signal-to-Noise Ratio (PSNR), Structural Similarity Index (SSIM)Most metrics passed.
    Deep Resolve SharpPSNR, SSIM, Perceptual Loss, Visual Rating, Image sharpness evaluation by intensity profile comparisonsVerified and validated by in-house tests, including visual rating and evaluation of image sharpness.
    Deep Resolve Swift BrainPSNR, SSIM, Normalized Mean Squared Error (NMSE), Visual InspectionAfter successful passing of quality metrics tests, work-in-progress packages were delivered and evaluated in clinical settings with collaboration partners. Potential artifacts not well-captured by metrics were detected via visual inspection.

    2. Sample Sizes Used for the Test Set and Data Provenance

    The document uses "Training and Validation data" and often refers to the datasets used for both. It is not explicitly stated what percentage or how many cases from these datasets were strictly reserved for a separate "test set" and what came from the "validation sets." However, given the separation in slice count, the "Validation" slices for Deep Resolve Swift Brain might be considered the test set.

    • Deep Resolve Boost:
      • TSE: >25,000 slices
      • HASTE: >10,000 HASTE slices (refined)
      • EPI Diffusion: >1,000,000 slices
      • Data Provenance: Retrospectively created from acquired datasets. Data covered a broad range of body parts, contrasts, fat suppression techniques, orientations, and field strength.
    • Deep Resolve Sharp:
      • Data: >10,000 high resolution 2D images
      • Data Provenance: Retrospectively created from acquired datasets. Data covered a broad range of body parts, contrasts, fat suppression techniques, orientations, and field strength.
    • Deep Resolve Swift Brain:
      • 1.5T Validation: 3,616 slices (This functions as a test set for 1.5T)
      • 3T Validation: 6,048 slices (This functions as a test set for 3T)
      • Data Provenance: Retrospectively created from acquired datasets.

    The document does not explicitly state the country of origin for the data.

    3. Number of Experts Used to Establish the Ground Truth for the Test Set and Qualifications of Those Experts

    The document does not explicitly state the number or qualifications of experts used to establish the ground truth for the test sets. For Deep Resolve Swift Brain, it mentions "evaluated in clinical settings with collaboration partners," implying clinical experts were involved in the evaluation, but details are not provided. For Boost and Sharp, the "acquired datasets...represent the ground truth," suggesting the raw imaging data itself, rather than expert annotations on that data, served as ground truth.

    4. Adjudication Method for the Test Set

    The document does not describe a formal adjudication method (e.g., 2+1, 3+1). For Deep Resolve Swift Brain, it mentions "visually inspected" and "evaluated in clinical settings with collaboration partners," suggesting a qualitative assessment, but details on consensus or adjudication are missing.

    5. If a Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study was Done, If so, what was the effect size of how much human readers improve with AI vs without AI assistance

    A formal MRMC comparative effectiveness study demonstrating human reader improvement with AI vs. without AI assistance is not described in the provided text. The studies focus on the AI's standalone performance in terms of image quality metrics and internal validation.

    6. If a Standalone (i.e. algorithm only without human-in-the-loop performance) was Done

    Yes, standalone performance was done for the AI features. The "Test Statistics and Test Results Summary" for Deep Resolve Boost, Deep Resolve Sharp, and Deep Resolve Swift Brain describe the evaluation of the algorithm's output using quantitative metrics (PSNR, SSIM, NMSE) and visual inspection against reference standards, which is characteristic of standalone performance evaluation.

    7. The Type of Ground Truth Used

    For Deep Resolve Boost, Deep Resolve Sharp, and Deep Resolve Swift Brain, the ground truth used was the acquired high-quality datasets themselves. The input data for training and validation was then retrospectively created from this ground truth by manipulating or augmenting it (e.g., undersampling k-space, adding noise, cropping, using only the center part of k-space). This means the original, higher-quality MR images or k-space data served as the reference for what the AI models should reconstruct or improve upon.

    8. The Sample Size for the Training Set

    • Deep Resolve Boost:
      • TSE: >25,000 slices
      • HASTE: pre-trained on the TSE dataset and refined with >10,000 HASTE slices
      • EPI Diffusion: >1,000,000 slices
    • Deep Resolve Sharp: >10,000 high resolution 2D images
    • Deep Resolve Swift Brain: 20,076 slices

    9. How the Ground Truth for the Training Set Was Established

    For Deep Resolve Boost, Deep Resolve Sharp, and Deep Resolve Swift Brain, the "acquired datasets (as described above) represent the ground truth for the training and validation." This implies that high-quality, fully acquired MRI data was considered the ground truth. The input data used during training (e.g., undersampled, noisy, or lower-resolution versions) was then derived or manipulated from this original ground truth. Essentially, the "ground truth" was the optimal, full-data acquisition before any degradation was simulated for the AI's input.

    Intended Use

    The Levita Magnetic Surgical System is designed to grasp and retract the body and the fundus of the gallbladder in laparoscopic cholecystectomy procedures; the liver in bariatric procedures; the pillar of the diaphragm and peripillar tissue in bariatric or hiatal hernia procedures; the prostate and periprostatic tissue in prostatectomy procedures; and the colon, rectum, and pericolorectal tissue in colorectal procedures to facilitate access and visualization of the surgical site. The device is indicated for use in patients with a BMI range of 20-60-kg/m2.

    The Grasper Tip, 12.5 is designed to grasp and retract the pillar of the diaphragm and peripillar tissue in bariatric or hiatal hernia procedures to facilitate access and visualization of the surgical site. The device is indicated for use in patients with a BMI range of 20-60 kg/m2.

    Device Description

    The Magnetic Surgical System comprises two hand-held instruments, the Magnetic Grasper and the external Magnetic Controller. The Magnetic Grasper, disposable and provided sterile for single use, comprises two main components: a detachable Grasper Tip (6.5cm overall length) and a Shaft with Handle. An optional 12.5cm length Grasper Tip (also single use, disposable, and provided sterile) may be used as a replacement for the 6.5cm Grasper Tip and can be used interchangeably with the Shaft.

    The Magnetic Grasper is actuated via its pistol-grip handle with two distinct scissor-type motions to open and close the Grasper Tip jaws. Once the Magnetic Grasper is inserted through a compatible ≥ 10 mm laparoscopic port to the surgical site and the Grasper Tip is attached to the desired tissue, the Grasper Tip can be detached from the Shaft and controlled externally using the Magnetic Controller. Traction of the tissue is maintained through the magnetic field attraction between the Grasper Tip and the Magnetic Controller.

    The Magnetic Controller is a non-sterile, reusable unit with handles that is held external to the body and emits a magnetic field that attracts the detachable Grasper Tip. Once the Grasper Tip is attached to the desired tissue and detached from the Shaft, the Magnetic Controller is placed external to the body to magnetically attract the Grasper Tip to manipulate the target tissue. Adjusting the distance between the Magnetic Controller and the Grasper Tip will modulate the magnetic attraction used for tissue retraction/mobilization. If desired, the user can connect the Magnetic Controller to a commercially available surgical support arm that is compatible with its arm mount.

    2. Sample Size Used for the Test Set and Data Provenance

    For the clinical study:

    • Sample Size: Thirty (30) subjects.
    • Data Provenance: Prospective, single-arm, open-label clinical study conducted at three (3) sites in Santiago, Chile.

    3. Number of Experts Used to Establish the Ground Truth for the Test Set and Their Qualifications

    The document does not explicitly state the number of experts used to establish ground truth or their specific qualifications for the clinical study. It mentions that "five (5) surgeons" performed the surgeries and evaluated the device's performance, implying their clinical judgment served as the ground truth. However, their specific qualifications (e.g., years of experience, specialization) are not detailed beyond being "surgeons."

    4. Adjudication Method for the Test Set

    The document does not specify an adjudication method like 2+1 or 3+1. Given it was a single-arm, open-label study where surgeons performed the procedures and evaluated outcomes, the assessment of safety and performance endpoints likely relied on the treating physicians' observations and reporting, aligned with the study protocol. There is no mention of an independent adjudication committee for specific endpoints.

    5. If a Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study Was Done, and Effect Size

    No, a Multi-Reader Multi-Case (MRMC) comparative effectiveness study was not done for this submission. The clinical study was a single-arm study evaluating the device's performance directly, not comparing human readers with and without AI assistance.

    6. If a Standalone (i.e., algorithm only without human-in-the-loop performance) Was Done

    This device is a physical surgical system (magnetic grasper and controller), not an algorithm or AI software. Therefore, the concept of "standalone (algorithm only)" performance is not applicable. The device's performance inherently involves human surgeons operating it.

    7. The Type of Ground Truth Used

    For the clinical study, the ground truth was established by clinical observation and assessment by the operating surgeons based on predefined safety and performance endpoints. This can be categorized as expert consensus/clinical judgment from the treating surgeons. The document states:

    • "The study results met all predefined safety and performance endpoints."
    • "The MSS was able to grasp the pillar of the diaphragm or peripillar tissue to adequately mobilize the liver, achieving an effective exposure of the target tissue."

    8. The Sample Size for the Training Set

    The document describes a physical medical device and primarily focuses on its hardware components and clinical performance. There is no mention of a "training set" in the context of an algorithm or AI model development. Therefore, this information is not applicable.

    9. How the Ground Truth for the Training Set Was Established

    As there is no mention of a "training set" for an algorithm, this question is not applicable.

    AI/ML Overview

    Below is a summary of the acceptance criteria and the study that proves the device meets the criteria.

    1. Table of Acceptance Criteria and Reported Device Performance

    Test CategoryAcceptance Criteria (Implied)Reported Device Performance
    Electromagnetic Compatibility (EMC)Compliance with IEC 60601-1-2. Demonstrated equivalent EMC level to the primary predicate device.The Horizon 3.0 TMS Therapy System was tested and found compliant with IEC 60601-1-2, demonstrating an equivalent level of EMC as the primary predicate device.

Ability of Horizon Air Film Coil and Horizon 3.0 Ez Cool Coil to execute OCD, iTBS, and rTMS protocols at worst-case ambient conditions without excessive temperatures.The system was compliant with IEC 60601-1. Additional testing confirmed the Horizon Air Film Coil and Horizon 3.0 Ez Cool Coil could perform protocols safely and effectively, even at worst-case ambient conditions (80%-100% output, 30°C), comparable to the predicate.
    Software Verification & ValidationAppropriate function of software, demonstrating it cannot contribute to any unacceptable risk (following IEC 62304 and FDA Software Guidance). Software behavior is consistent and compatible across all configurations and fulfills its intended use, with cybersecurity tested to ensure security equivalent to the primary predicate.Software development followed IEC 62304. Lifecycle documentation demonstrated appropriate function and no unacceptable risk. Software behavior was consistent, compatible, and passed cybersecurity testing, ensuring security equivalent to the primary predicate.
    Usability/Human Factors EngineeringAppropriate human factors and usability for intended use, free from unacceptable use-related risks (following IEC 60601-1-6, IEC 62366-1, ANSI/AAMI HE75). Consistency of workflows, UIs, and components promoting a healthy usability profile.Human factors evaluation demonstrated appropriate usability and freedom from unacceptable use-related risks. Consistency across configurations promotes a healthy usability profile.
    Magnetic Pulse Output & Field TestingEquivalence of electric field distribution, power outputs, magnetic fields, field spatial distribution, E-field decay, output waveforms, magnetic field strength, and rate of change between subject coils (Ez Cool Coil, Air Film Coil) and predicate coil (Neuronetics Coil) at clinically relevant depths (2-3cm). Compliance with Special Controls: 21 C.F.R. § 882.5802, 21 C.F.R. § 882.5805, and FDA Guidance "Repetitive Transcranial Magnetic Stimulation (rTMS) Systems."Measurements in a phantom head model showed equivalent power outputs, electric and magnetic fields, and key field characteristics between the subject and predicate coils at clinically relevant depths (2-3cm).
    Safety Feature TestingMaintenance of appropriate safety features, exercising many fault scenarios, and ensuring interlocks with respect to safety features (following IEC 60601-1). Testing includes introducing failure modes to test multiple fault conditions (e.g., disabling software check and ensuring hardware backup interlock is active).All fault scenarios and safety features were tested and complied with IEC 60601-1, demonstrating substantial equivalence of safety features among all device configurations.
    Acoustic TestingSystem does not reach excessive/unacceptable noise levels under simulated use scenarios with Horizon Air Film Coil and Horizon 3.0 Ez Cool Coil (following IEC 60601-1).Acoustic testing under simulated use scenarios (maximum machine output for recommended protocols) demonstrated the system with the specified coils does not reach excessive/unacceptable noise levels.

    2. Sample Size Used for the Test Set and Data Provenance

    The summary details a series of non-clinical tests. These tests primarily involve physical measurements and simulations, rather than collecting data from human subjects.

    • Sample Size for Test Set: Not applicable in the traditional sense of human subjects. For the magnetic and electrical field testing, the "test set" was the physical setup involving a phantom head model and specific coils. No numerical sample size for patients is provided.
    • Data Provenance: The data comes from in-house engineering and laboratory testing performed by The Magstim Company Limited, in accordance with international standards. This is not retrospective or prospective clinical data from human patients, but rather performance data generated from the device itself and its components. The country of origin for the testing is implicitly the United Kingdom, where the applicant is located.

    3. Number of Experts Used to Establish Ground Truth for the Test Set and Their Qualifications

    Given the nature of the non-clinical tests described, the concept of "experts establishing ground truth" for a test set in a human clinical context is not directly applicable.

    • Magnetic and Electrical Field Testing: This testing involved physical measurements using a phantom head model and measuring probes. The "ground truth" here is the physical output of the device under controlled conditions, measured against established scientific principles and comparison to a legally marketed predicate device. The expertise involved would be in engineering, physics, and medical device testing, ensuring the test setup, execution, and interpretation of results are scientifically sound and comply with regulatory guidance.
    • Other Non-Clinical Tests: For areas like Electrical, Mechanical, Thermal Safety, EMC, Software V&V, Usability, Safety Features, and Acoustic Testing, compliance is determined by adherence to specific international standards (e.g., IEC 60601 series, IEC 62304, ISO 10993, AAMI/ANSI HE75) and FDA guidance documents. The "ground truth" is defined by these standards and the expertise lies with the engineers and quality assurance personnel who conduct these tests and verify compliance.

    No specific number or qualifications of "experts" are provided in the summary, as this is typically inherent in the regulatory-compliant testing process conducted by the manufacturer.

    4. Adjudication Method for the Test Set

    Not applicable. Adjudication methods like 2+1 or 3+1 are typically used in clinical studies involving interpretation of medical images or patient outcomes, where ambiguous cases require expert consensus. The tests described here are non-clinical, objective measurements and compliance checks against established standards.

    5. If a Multi Reader Multi Case (MRMC) Comparative Effectiveness Study Was Done

    No, an MRMC comparative effectiveness study was not done. The summary explicitly states: "Clinical Testing - Not Applicable." The submission relies solely on non-clinical testing to demonstrate substantial equivalence.

    6. If a Standalone (Algorithm Only Without Human-in-the-Loop Performance) Was Done

    This question is not entirely applicable as the device in question (Horizon 3.0 TMS Therapy System) is a hardware-based medical device that delivers magnetic stimulation. While it contains software, it is not an AI algorithm that generates diagnostic outputs or interpretations that would typically have a "standalone" performance metric in the absence of human input or a human-in-the-loop. The software functions to control the hardware and deliver therapy protocols, and its performance is validated as part of the overall device system.

    7. The Type of Ground Truth Used

    The ground truth used for these non-clinical tests is primarily based on:

    • Compliance with International Standards: The device's performance is measured against established safety, EMC, thermal, electrical, mechanical, and software standards (e.g., IEC 60601 series, IEC 62304).
    • Scientific Principles and Physical Measurements: For magnetic and electrical field testing, the ground truth is derived from quantitative physical measurements conducted in a controlled phantom head model according to scientific principles.
    • Comparison to a Legally Marketed Predicate Device: Substantial equivalence is established by demonstrating that the subject device's performance characteristics (e.g., magnetic field output, treatment protocols) are equivalent to those of the predicate device (NeuroStar Advanced Therapy System) and previously cleared Magstim devices.

    There is no pathology, expert consensus (in a diagnostic sense), or outcomes data from human patients used as ground truth in this submission, as it focuses on non-clinical performance.

    8. The Sample Size for the Training Set

    Not applicable. This device is a medical device for therapy, not a machine learning model that requires a distinct "training set" of data in the AI sense. The software embedded in the device is developed and validated through traditional software engineering practices (IEC 62304), not through machine learning training on a dataset.

    9. How the Ground Truth for the Training Set Was Established

    Not applicable, as there is no machine learning "training set" for this device. The software development and validation followed established engineering principles and regulatory standards (IEC 62304), which ensure the software functions as intended and meets safety requirements.

    Intended Use

    ME-APDS (Magentig Eye's Automatic Polyp Detection System) is intended to be used by endoscopists as an adjunct to the common video colonoscopy procedure (screening and surveillance), aiming to assist the endoscopist in identifying lesions during colonoscopy procedure by highlighting reqions with visual characteristics consistent with different types of mucosal abnormalities that appear in the colonoscopy video during the procedure. Highlighted regions can be independently assessed by the endoscopist and appropriate action taken according to standard clinical practice.

    ME-APDS is trained to process video images which may contain regions consistent with polyps.

    ME-APDS is limited for use with standard white-light endoscopy imaging only.

    ME-APDS is intended to be used as an adjunct to endoscopy procedures and is not intended to replace histopathological sampling as means of diagnosis.

    Device Description

    ME-APDS™MAGENTIQ-COLO is intended to be used as an adjunct to the common video colonoscopy procedure. The system application aims to assist the endoscopist in identifying lesions, such as polyps, during the colonoscopy procedures in real time. The device is not intended to be used for diagnosis or characterization of lesions, and does not replace clinical decision making.

    The system acquires the digital video output signal from the local endoscopy camera and processes the video frames. It runs deep machine learning and additional supporting algorithms in real time on the video frames in order to detect and identify regions having characteristics consistent with different types of mucosal abnormalities such as polyps. The output video with the detected lesions is presented on a separate screen, highlighting the suspicious areas on the original video. The user can also take snapshots of the videos, with and without the highlighting of the suspicious areas, record videos and view in full screen mode.

    AI/ML Overview

    Here's an analysis of the acceptance criteria and study details for the MAGENTIQ-COLO device, based on the provided document:

    1. Acceptance Criteria and Reported Device Performance

    The acceptance criteria are implied by the reported performance metrics, particularly "Polyp-wise Recall" and "False Positives Per Frame (FPPF)". The study aims to demonstrate that the device performs comparably to or better than the predicate device.

    Acceptance Criteria / MetricReported Device Performance (Full Testing Dataset)
    Polyp-wise Recall (PRecall1)97.9% [96.63%, 98.94%]
    Polyp-wise Recall (PRecall3)95.3% [93.39%, 96.96%]
    Polyp-wise Recall (PRecall5)93.2% [91.01%, 95.15%]
    Polyp-wise Recall (PRecall7)90.6% [88.19%, 92.91%]
    False Positives Per Frame (FPPF)0.0333 (threshold achieved)
    Polyps with Histology: PRecall199.7% [99.12%, 100.0%]
    Polyps with Histology: PRecall799.7% [99.11%, 100.0%]
    Median Coverage of Polyps (with histology)81.7%
    Marker Annotation Latency (Median)133 msec for FHD, 157 msec for 4K

    Note: The document states that "The testing results were observed to be as expected and support that the device has similar performance to the predicate device," implying that these reported values met the implicit acceptance criteria for substantial equivalence.

    2. Sample Size Used for the Test Set and Data Provenance

    • Sample Size (Test Set): 212 unique full colonoscopy videos, containing 702 polyps (16 videos contained no polyps).
    • Data Provenance: The document does not explicitly state the country of origin or whether the data was retrospective or prospective.

    3. Number of Experts Used to Establish Ground Truth for the Test Set and Their Qualifications

    The document does not explicitly state the number of experts used to establish the ground truth or their specific qualifications (e.g., "radiologist with 10 years of experience"). However, it references polyps "verified by histology" and "reported in the procedure report," implying clinical expert input.

    4. Adjudication Method for the Test Set

    The document does not describe a specific adjudication method like 2+1 or 3+1. The ground truth seems to be derived from documented polyps in the "procedure report" and "histology findings," suggesting a standard clinical reporting process rather than a specific consensus method for this study.

    5. Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study

    No, a multi-reader multi-case (MRMC) comparative effectiveness study was not reported in this document. The study described is a standalone performance test of the algorithm. The document mentions that the clinical validation used to support the device's polyp detection functions was conducted in a previous submission (K223473). This K223473 submission might contain an MRMC study, but it's not detailed here.

    6. Standalone (Algorithm Only Without Human-in-the-Loop Performance) Study

    Yes, a standalone performance study was done. The "Standalone Performance Testing" section describes how "The algorithm was tested offline" on an independent dataset to evaluate its recall, false positive performance, and false positives per full video rate without direct human interaction during the test.

    7. Type of Ground Truth Used

    The ground truth used for the test set was a combination of:

    • Histopathology findings: For polyps with histology reports.
    • Procedure reports: For polyps identified and documented during the colonoscopy procedure.

    8. Sample Size for the Training Set

    The document does not provide the sample size for the training set. It only states that "ME-APDS is trained to process video images which may contain regions consistent with polyps."

    9. How the Ground Truth for the Training Set Was Established

    The document does not provide information on how the ground truth for the training set was established. It only broadly states that the system "runs deep machine learning" and is "trained to process video images."

    AI/ML Overview

    The provided text is a 510(k) summary for the Horizon 3.0 TMS Therapy System, specifically introducing the "Horizon 3.0 Inspire" configuration. This document primarily focuses on demonstrating substantial equivalence to a legally marketed predicate device (K232235, Horizon 3.0 TMS Therapy System) rather than presenting a standalone study with defined acceptance criteria and performance metrics against a specific clinical outcome.

    Therefore, the requested information, particularly regarding acceptance criteria for clinical performance, sample sizes for test sets where ground truth was established by experts, and effect sizes for MRMC studies, is not present in this document. The document describes non-clinical testing to demonstrate that the new configuration is as safe and effective as the predicate device.

    Here's a breakdown of the available information based on your request:

    1. Table of Acceptance Criteria and Reported Device Performance:

    The document describes compliance with various safety and performance standards, but does not present a table of acceptance criteria with corresponding performance results in a way that would typically be seen for a new clinical efficacy study. Instead, it refers to demonstrating equivalence to a predicate device through non-clinical testing.

    Acceptance Criteria CategoryDescription of Compliance/Performance
    Electromagnetic Compatibility (EMC)Compliant "to the requirements of IEC 60601-1-2 to demonstrate an equivalent level of Electromagnetic Compatibility as the primary predicate device." Test plan utilized the same performance criteria as the primary predicate.
    Electrical & Mechanical SafetyCompliant "to the requirements of IEC 60601-1 (including IEC 60601-1-8) to demonstrate an equivalent level of Electrical and Mechanical safety as the primary predicate device."
    Thermal SafetyCompliant "to the requirements of IEC 60601-1 (including IEC 60601-1-6 and IEC 60601-1-8) to demonstrate an equivalent level of Thermal safety as the primary predicate device." Additional testing ensured the Horizon Air Film Coil could execute OCD, iTBS, and rTMS protocols at worst-case ambient conditions without excessive temperatures. The system can perform recommended protocols safely and effectively under worst-case simulated ambient conditions (80%-100% machine output, 30°C ambient).
    Software Verification & ValidationSoftware developed following IEC 62304. Documentation demonstrates appropriate function and that software cannot contribute to unacceptable risk. Changes for "Inspire" configuration verified for correctness and no negative impact on predicate configurations. Cybersecurity testing performed to ensure "Inspire" configuration is as secure as the primary predicate.
    Usability/Human Factors EngineeringEvaluation demonstrates appropriate human factors and usability for intended use, free from unacceptable use-related risks (IEC 60601-1-6, IEC 62366-1, ANSI/AAMI HE75). Consistency of workflows, UIs, and components from predicate contribute to a healthy usability profile.
    Magnetic Pulse Output Testing and Magnetic & Electrical Field TestingElectric field distribution measured in a human head phantom filled with physiologic saline solution. Values of Magnetic and Electric field obtained by measuring induced voltage. Results demonstrated "equivalent Power Outputs, Electric Fields between the subject device configuration applicating coil and the primary predicate device configuration applicating coil." Key characteristics (stimulator output, field spatial distribution, E-Field decay, output waveforms, rate of change) were equivalent, especially at clinically relevant depths.
    Safety Feature TestingIEC 60601-1 testing of fault scenarios to ensure appropriate safety features. System-level testing (software verification) exercised various interlocks. Testing introduced failure modes to confirm hardware backup interlocks. Demonstrates substantial equivalence of safety features.
    Acoustic TestingIn simulated use scenarios (OCD Protocol at maximum machine output), the Horizon 3.0 "Inspire" configuration demonstrated equivalent acoustic properties to the predicate and fell below safe exposure limits.

    2. Sample size used for the test set and the data provenance:

    • Test Set: No patient-specific test set for clinical performance is mentioned. The testing described is non-clinical/bench testing.
    • Data Provenance: The data provenance is from laboratory testing performed by the manufacturer, comparing the new configuration's performance to the primary predicate device and relevant standards. This is retrospective in the sense that it relies on existing standards and predicate device data, but the tests themselves were conducted on the new device configuration.

    3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts (e.g. radiologist with 10 years of experience):

    This information is not applicable as the document describes non-clinical testing against engineering standards and comparison to a predicate device, not a human reader study where experts establish ground truth for a clinical dataset.

    4. Adjudication method (e.g. 2+1, 3+1, none) for the test set:

    This information is not applicable for the same reasons as point 3.

    5. If a multi reader multi case (MRMC) comparative effectiveness study was done, If so, what was the effect size of how much human readers improve with AI vs without AI assistance:

    No MRMC comparative effectiveness study was done or described. This is a device for Transcranial Magnetic Stimulation, not typically an imaging AI device that aids human readers in interpretation.

    6. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done:

    The device itself is a standalone medical device for delivering TMS therapy. The described testing is of the device's technical specifications and safety profile, not of an "algorithm only" in the context of an AI diagnostic. The software components were verified and validated as part of the overall device system.

    7. The type of ground truth used (expert consensus, pathology, outcomes data, etc):

    For the non-clinical tests described, the "ground truth" (or reference) used were:

    • International standards: (e.g., IEC 60601-1, IEC 60601-1-2, IEC 60601-1-8, IEC 62366-1, ANSI/AAMI HE75, ISO 10993-1, ISO 10993-10, ISO 14971, IEC 62304, AAMI TRS7, AAMI TIR97).
    • Performance of the legally marketed predicate device (K232235): The goal was to demonstrate "equivalent" safety and effectiveness.
    • Phantom head model: For Magnetic and Electrical Field Testing, a human head phantom model filled with physiologic saline solution was used to measure induced voltage.

    8. The sample size for the training set:

    This information is not applicable. This document does not describe the development or training of a machine learning algorithm; it describes a hardware and software system for TMS therapy.

    9. How the ground truth for the training set was established:

    This information is not applicable for the same reason as point 8.

    Intended Use

    The Apollo TMS Therapy System is indicated for the treatment of Major Depressive Disorder in adult patients who have failed to achieve satisfactory improvement from prior antidepressant medication in the current episode.

    Device Description

    The Apollo TMS Therapy System is an electromagnetic device that non-invasively delivers a rapidly pulsed magnetic field to the cerebral cortex in order to activate neurons within a limited volume without inducing a seizure. This method of cortical stimulation by application of brief magnetic pulses to the head is known as Transcranial Magnetic Stimulation (TMS).

    The Apollo TMS Therapy System is comprised of the following principal components:

    • User Interface
    • Main Unit (with or without housing)
    • Stimulation Coil
    • Coil Positioning System

    The operator controls the Apollo TMS Therapy System via the user interface (application software "Stimware"). "Stimware" is a treatment and data management software that administrates treatment protocols and the patient´s individual stimulation dose determined by the patient´s individual motor threshold. Stimulation is applied via the stimulation coil which is positioned to the left dorsolateral prefrontal cortex (DLPFC) by means of a coil positioning system. The observed and documented increase in cortical excitability after high frequency (10Hz) rTMS has been shown to persist beyond the duration of the train of stimulation.

    AI/ML Overview

    This document does not contain information about a study proving the device meets acceptance criteria. Instead, it is a 510(k) summary for the Apollo TMS Therapy System, demonstrating its substantial equivalence to previously cleared predicate devices for the treatment of Major Depressive Disorder.

    Therefore, I cannot provide the requested information regarding:

    • A table of acceptance criteria and reported device performance.
    • Sample size used for the test set and data provenance.
    • Number of experts and their qualifications for ground truth establishment.
    • Adjudication method for the test set.
    • MRMC comparative effectiveness study results.
    • Standalone performance.
    • Type of ground truth used.
    • Sample size for the training set.
    • How ground truth for the training set was established.

    The document primarily focuses on:

    • Intended Use and Device Description: The Apollo TMS Therapy System is an electromagnetic device for non-invasive stimulation of the cerebral cortex to treat Major Depressive Disorder.
    • Compliance with Standards: Conforms to various ISO and IEC standards for medical devices, electrical safety, usability, software life cycle processes, and risk management.
    • Non-Clinical and Clinical Performance Data: States that non-clinical testing was performed according to standards, and comparative testing for additional coils demonstrated substantial equivalence to predicate devices. It specifically mentions that clinical data on the treatment efficacy of the iTBS protocol was already demonstrated in a previous summary (K173620) and that verification testing confirmed constant intensity of individual stimuli.
    • Software Verification and Validation: Conducted in accordance with IEC 62304, considered "basic documentation" as software failures are not likely to present high-risk situations.
    • Risk Management: Applied throughout the product development life cycle, concluding no new hazards compared to predicate devices.
    • Substantial Equivalence: The core of the submission, asserting that the Apollo TMS Therapy System is substantially equivalent to the HORIZON® TMS Therapy System (K182853) and an earlier version of the Apollo TMS Therapy System (K180313). This equivalence is based on identical intended use, indications for use, system components, operational procedures, and treatment protocols (especially iTBS).
    • Comparative Table: Provides a detailed comparison of characteristics between the subject device and its predicates, highlighting similarities in indications for use, product code, classification, standard treatment stimulation parameters (e.g., area of brain stimulated, stimulation intensity, frequency, pulse train duration), output stimulation parameters, and coil parameters. It explicitly notes that the performance and clinical effectiveness are substantially equivalent.

    In summary, this document is a regulatory submission demonstrating substantial equivalence rather than a clinical study report with specific acceptance criteria and performance data from a clinical trial.

    Magic Mobility

    AI/MLSaMDIVD (In Vitro Diagnostic)TherapeuticDiagnosticis PCCP AuthorizedThirdpartyExpeditedreview
    Intended Use

    The XT2 power wheelchair is a battery-operated device with wheels that is intended for medical purposes to provide mobility to persons restricted to a sitting position who have the capability of operating a power wheelchair. The XT4 power wheelchair is a battery-operated device with wheels that is intended for medical purposes to provide mobility to persons restricted to a sitting position who have the capability of operating a power wheelchair.

    Device Description

    The XT Series Power Wheelchair has two configurations: XT2 and XT4. They are designed for everyday use for both indoor and outdoor environments including care facilities and private residences. The subject device is intended to provide mobility to persons who are restricted or limited to a sitting position. The XT Series Power Wheelchairs are battery powered, electric motor driven devices that can be used on both indoor and outdoor surfaces (i.e., concrete, asphalt, indoor flooring such as carpet, gravel, grass, and bark/woodchips). The XT Series Power Wheelchair offers two basic seating options: MPS and Rehab. The MPS option is more static and does not allow for additional aftermarket cushions. The Rehab option is more adjustable to adhere to recommendations from the user's physician or physical therapist.

    AI/ML Overview

    The provided document is an FDA 510(k) clearance letter and summary for a Magic Mobility XT Series Power Wheelchair. It details the device's technical specifications, indications for use, and a comparison to predicate devices, along with the non-clinical testing performed to establish substantial equivalence.

    However, the document does not contain any information about an AI/ML-based medical device, nor does it include details about a study conducted to demonstrate its performance against specific acceptance criteria for such a device. The device described, a powered wheelchair, is a physical medical device, not a software or AI-driven diagnostic or therapeutic tool that would typically have acceptance criteria related to accuracy, sensitivity, specificity, or human-in-the-loop performance improvement.

    Therefore, I cannot provide the requested information regarding acceptance criteria and a study proving an AI/ML device meets them, a sample size, expert qualifications, ground truth establishment, or MRMC studies, as these concepts are not applicable to the content of the provided document.

    The document focuses on non-clinical bench testing to demonstrate the safety and effectiveness of the physical wheelchair in comparison to existing predicate devices, primarily through adherence to ISO standards for wheelchairs.

    To directly answer your prompt, based on the provided text:

    1. A table of acceptance criteria and the reported device performance:

    • This document does not present acceptance criteria or reported performance for an AI/ML device. It lists various ISO standards that the physical wheelchair was tested against. The "reported device performance" is essentially that it met these standards, thus demonstrating substantial equivalence to predicate devices. For example, for "Static stability," the acceptance criterion is compliance with ISO 7176-1, and the reported performance is implicit compliance as it contributed to the substantial equivalence determination.

    IEC 62304: Software life cycle processMet standard

    2. Sample size used for the test set and the data provenance:

    • Not applicable/Not provided for an AI/ML device. The "test set" here refers to the physical wheelchairs undergoing bench testing. The sample size for such physical product testing is not specified, but typically involves a small number of units. Data provenance (country of origin, retrospective/prospective) is not relevant for this type of medical device testing.

    3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts:

    • Not applicable. "Ground truth" in the context of an AI/ML device's performance (e.g., disease detection) is not established for a physical powered wheelchair. The "truth" for this device is its adherence to engineering standards.

    4. Adjudication method (e.g. 2+1, 3+1, none) for the test set:

    • Not applicable. This is a concept for reconciling disagreements among human readers in a diagnostic AI/ML study, not for physical product testing.

    5. If a multi reader multi case (MRMC) comparative effectiveness study was done, If so, what was the effect size of how much human readers improve with AI vs without AI assistance:

    • No, an MRMC study was not done as this is a physical wheelchair, not an AI/ML diagnostic or assistive device.

    6. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done:

    • Not applicable. There is no AI algorithm being submitted for standalone performance evaluation in this document.

    7. The type of ground truth used (expert consensus, pathology, outcomes data, etc.):

    • Not applicable in the context of AI/ML. The "ground truth" for this device's performance is adherence to established international engineering and safety standards (e.g., ISO, IEC).

    8. The sample size for the training set:

    • Not applicable. This document does not describe an AI/ML device, so there is no training set for an algorithm.

    9. How the ground truth for the training set was established:

    • Not applicable for the same reason as above.
