    The document focuses on non-clinical performance testing and comparative analysis against a predicate device. There is no mention of a "test set" in the context of clinical data or human-interpreted image sets for evaluating device diagnostic performance. The studies are non-clinical, evaluating technical specifications of the device itself.

    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)

    Not applicable. The reported studies are non-clinical and focus on characterizing device performance parameters (e.g., MTF, DQE, uniformity) rather than diagnostic accuracy based on expert interpretation of images. Therefore, no experts were used to establish ground truth for a diagnostic test set.

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

    Not applicable. As no clinical or human-interpreted test set was used, no adjudication method was employed.

    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

    Not applicable. This submission is for a Digital Flat Panel Detector, which is an imaging component. It is not an AI-powered diagnostic device, and therefore, no MRMC study or evaluation of human reader improvement with AI assistance was performed.

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

    Not applicable. The device is a Digital Flat Panel Detector, a hardware component for X-ray imaging. Performance is evaluated based on its technical specifications (e.g., MTF, DQE, SNR, uniformity) through non-clinical studies. There is no "algorithm only" performance assessment in the context of diagnostic interpretation.

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

    The "ground truth" for the non-clinical studies relies on established scientific and engineering principles for measuring physical parameters of X-ray detectors (e.g., using phantoms, standardized test setups, and calibrated equipment to measure MTF, DQE, SNR, etc.). It does not involve expert consensus, pathology, or outcomes data in a clinical sense.

    8. The sample size for the training set

    Not applicable. This device is a hardware component and does not utilize a "training set" in the context of machine learning or AI algorithms.

    This device is suitable for providing radiography imaging for adult via DR system. The remaining notes depend on the final DR system.

    It is not intended for mammography, dental applications, neonatal and fluoroscopy.

    Device Description

    Digital flat panel detector is a cassette-size wired X-ray flat panel detector based on amorphous silicon thin-film transistor technologies. It was developed to provide X -Ray image, which contains an active matrix of 3064×8696 with 139um pixel pitch. Detector's scintillator is CsI(Cesium iodide). The biggest feature of Venu1748V is that it supports imaging of large-scale objects, including long bones and complete spine detection.

    AI/ML Overview

    This document is a 510(k) Pre-Market Notification from iRay Technology Taicang Ltd. to the FDA for their Digital Flat Panel Detector, model Venu1748V. It outlines the device's technical characteristics and compares them to a predicate device.

    Analysis of Acceptance Criteria and Study Details:

    The provided document does not describe a clinical study or a multi-reader, multi-case (MRMC) study to prove the device meets acceptance criteria. Instead, it relies on non-clinical studies (bench testing) to demonstrate substantial equivalence to a predicate device. This is a common approach for imaging components like flat panel detectors where the primary concern is the technical performance of the imaging hardware itself, rather than diagnostic accuracy involving human interpretation when coupled with a full DR system.

    Therefore, many of the requested points regarding clinical study design, expert involvement, and human reader performance are not applicable to this submission.

    Here's a breakdown based on the provided text, addressing the points where information is available:

    1. Table of Acceptance Criteria and Reported Device Performance:

    The document doesn't explicitly state "acceptance criteria" in a separate table with pass/fail thresholds. Instead, it presents a comparison of key technical specifications between the proposed device (Venu1748V) and the predicate device (VIVIX-S 1751S). The implication is that meeting or exceeding the performance of the predicate device for these parameters constitutes "acceptance."

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

    • Sample Size: Not applicable. The "test set" here refers to the non-clinical bench testing of the detector's physical performance characteristics. These tests are typically performed on a limited number of manufactured units (e.g., a few samples per batch) to ensure they meet specifications. The document does not specify the exact number of units tested for each parameter.
    • Data Provenance: The company is iRay Technology Taicang Ltd., located in Taicang, Jiangsu, CHINA. The testing was performed internally or by a contracted lab. The data is retrospective in the sense that it was collected as part of the device's development and verification, prior to submission.

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

    Not applicable. For non-clinical tests of a flat panel detector, "ground truth" is established by physical measurement standards and calibrated equipment, not by human expert consensus or clinical diagnosis. For example, MTF is measured using a phantom and analytical methods, not by radiologists.

    4. Adjudication Method for the Test Set:

    Not applicable. Since no human experts are establishing ground truth for diagnostic decisions, there's no need for 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:

    No. The document explicitly states: "Clinical data is not needed to characterize performance and establish substantial equivalence. The non-clinical test data characterizes all performance aspects of the device based on well-established scientific and engineering principles." This device is a hardware component (a flat panel detector), not an AI algorithm assisting human readers.

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

    No. This is a hardware component. There is no "algorithm only" performance in the sense of an AI diagnostic tool. The detector captures raw image data.

    7. The Type of Ground Truth Used:

    The "ground truth" for the non-clinical tests consists of:

    • Physical standards/measurements: For parameters like dimensions, pixel pitch, greyscales, power consumption, temperature/humidity ranges.
    • Engineering metrics: For performance characteristics like MTF, DQE, spatial resolution, signal-to-noise ratio, uniformity, defect, minimum triggering dose rate, and low contrast resolution. These are established through standardized testing procedures using phantoms and calibrated instruments.
    • Compliance with standards: Electrical safety (IEC/ES 60601-1, IEC60601-2-54) and EMC testing (IEC 60601-1-2) ensure the device meets predefined safety and electromagnetic compatibility benchmarks.
    • Software verification: The software "iDetector" hazards, requirements specification, and design specification were tested against the intended design specification.

    8. The Sample Size for the Training Set:

    Not applicable. This is a hardware device. "Training set" typically refers to data used to train AI/machine learning models.

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

    Not applicable, as there is no training set mentioned for an AI/ML model for this hardware device.

    AI/ML Overview

    The provided text is a 510(k) summary for the iRay Technology Taicang Ltd. Wireless Digital Flat Panel Detector (Mars1013X). It describes the device, its intended use, and its comparison to predicate devices to demonstrate substantial equivalence.

    However, the document does NOT contain information about specific acceptance criteria related to a study proving the device meets those criteria in the context of AI/algorithm performance. It primarily focuses on the device's physical and technical specifications, electrical safety, biological evaluation, and comparison to predicate devices, but not on clinical performance metrics that would typically be established for an AI-powered diagnostic device.

    The provided text describes a "Wireless Digital Flat Panel Detector", which is a hardware component for X-ray imaging, not an AI or algorithmic diagnostic device. Therefore, the questions related to AI-specific acceptance criteria, test sets, ground truth establishment, expert adjudication, MRMC studies, and standalone algorithm performance are not applicable to the information contained in this document.

    The document states:

    • "Mars1013X Wireless Digital Flat Panel Detector is the kind of wireless digital flat panel detector. It supports the single frame mode, with the key component of TFT/PD image sensor flat panel of active area: 33.18cm×25.28cm"
    • "The major function of the Mars1013X is to convert the X-ray to digital image, with the application of high resolution X-ray imaging."

    The performance metrics discussed (Spatial Resolution, MTF, DQE) are physical imaging characteristics of the detector itself, not diagnostic performance of an AI analyzing the images.

    Therefore, it is not possible to extract the requested information regarding acceptance criteria and a study proving an AI device's performance from the provided text. The document pertains to the clearance of an X-ray detector, not an AI diagnostic algorithm.

    Intended Use

    Mars 1417X wireless digital flat panel detector is indicated for digital imaging solutions designed to provide general radiographic diagnosis for human anatomy including both adult and pediatric patients. It is intended to replace film/screen systems in all general-purpose diagnostic procedures. The device is not intended for mammography or dental applications.

    Device Description

    Mars1417X Wireless Digital Flat Panel Detector is a wireless digital flat panel detector that supports single frame mode. Its key component is a TFT/PD image sensor flat panel with an active area of 35cm×43cm. The sensor plate has a direct-deposited CsI scintillator to convert X-ray to visible photon. These visible photons are transformed to electron signals by a diode capacitor array within the TFT panel, which are composed and processed by connecting to scanning and readout electronics, forming a panel image transmitted to a PC through the user interface. The main function is to convert X-ray to digital image for high resolution X-ray imaging. It is a key component of a DR system, enabling the digitalization of medical X-ray imaging with DR system software. iRay SDK (including iDetector) provides an API interface for DR system manufacturers to control the detector.

    AI/ML Overview

    The provided text describes a 510(k) premarket notification for the Mars 1417X Wireless Digital Flat Panel Detector. This document primarily focuses on demonstrating substantial equivalence to a predicate device (Mars1417V-TSI) rather than presenting a standalone clinical study with detailed acceptance criteria and performance data.

    Therefore, the information required to answer most of your questions (especially those related to a clinical study, reader performance, and ground truth establishment) is not present in the provided text. The document states that "clinical consideration may not necessary for changes in the dimensions of the image receptor with otherwise identical materials if non-clinical information is sufficient to support the substantial equivalence." This implies that a formal clinical study, as you've outlined, was likely not conducted or required for this 510(k) clearance.

    However, I can extract the acceptance criteria and performance related to the device's technical specifications and non-clinical testing as presented in the document, comparing the proposed device (Mars1417X) to its predicate (Mars1417V-TSI).

    1. Sample size used for the test set and the data provenance: Not applicable in the context of clinical reads for performance testing. The "test set" here refers to the physical device's specifications being evaluated against the predicate. Data provenance is not described for any clinical study. The device manufacturer is iRay Technology Taicang Ltd. in China. The submission is for a 510(k) Pre-Market Notification, which relies on demonstrating substantial equivalence, often through non-clinical performance data and comparison to an existing device, rather than new clinical trials.

    2. Number of experts used to establish the ground truth for the test set and the qualifications of those experts: Not applicable. Ground truth for clinical diagnostic performance using expert consensus or pathology is not mentioned, as a clinical performance study of this nature was likely not performed.

    3. Adjudication method (e.g., 2+1, 3+1, none) for the test set: Not applicable. There is no mention of adjudication for a clinical test set.

    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: No, an MRMC study was not done, and this device is a digital flat panel detector, not an AI diagnostic algorithm. Its primary function is to convert X-rays to digital images, not to provide AI assistance to human readers.

    5. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done: Not applicable. This is not an algorithm but a hardware device. Its performance is measured by its raw imaging capabilities (e.g., spatial resolution, DQE).

    6. The type of ground truth used (expert consensus, pathology, outcomes data, etc): For the specified improvements (e.g., spatial resolution, DQE), the ground truth is established through physical measurements and standardized imaging tests as per industry standards (e.g., lp/mm, ISO standards for DQE measurement). For safety aspects, compliance with standards like IEC/ES 60601-1 and ISO 10993-1 establishes "ground truth" for electrical safety, EMC, and biological evaluation.

    7. The sample size for the training set: Not applicable. This is a hardware device, not an AI algorithm requiring a training set.

    8. How the ground truth for the training set was established: Not applicable.

    Mars1717X Wireless Digital Flat Panel Detector

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

    Mars1717X wireless digital flat panel detector is indicated for digital imaging solutions designed to provide general radiographic diagnosis for human anatomy including both adult and pediatric patients. It is intended to replace film/screen systems in all general-purpose diagnostic procedures. The device is not intended for mammography or dental applications.

    Device Description

    Mars1717X Wireless Digital Flat Panel Detectors (Hereinafter referred to as Mars1717X) is a kind of wireless digital flat panel detector. It supports the single frame mode, with the key component of TFT/PD image sensor flat panel of active area: 42.67cm×42.67cm.

    The sensor plate of Mars1717X is direct-deposited with CsI scintillator to achieve the conversion from X-ray to visible photon. The visible photons are transformed to electron signals by diode capacitor array within TFT panel, which are composed and processed by connecting to scanning and readout electronics, consequently to form a panel image by transmitting to PC through the user interface.

    The major function of the Mars1717X is to convert the X-ray to digital image, with the application of high resolution X-ray imaging. Both kinds of detectors are the key component of DR system, enable to complete the digitalization of the medical X-ray imaging with the DR system software.

    iRay SDK(include iDetector) is intended to supply API interface for DR system manufacturers. DR system manufacturer control the detector by SDK interface. SDK is not intend to be used directly by other users beside DR system manufacturers.

    AI/ML Overview

    The provided document is a 510(k) Summary for the Mars1717X Wireless Digital Flat Panel Detector by iRay Technology Taicang Ltd. This document primarily focuses on demonstrating substantial equivalence to a predicate device (Mars1717V-VSI, K201043) rather than detailing a specific study to prove the device meets acceptance criteria regarding clinical performance.

    The document states that clinical consideration may not be necessary for changes in image receptor dimensions if non-clinical information is sufficient to support substantial equivalence. This implies that a dedicated clinical study to evaluate the device against specific performance acceptance criteria for diagnostic accuracy (e.g., sensitivity, specificity for detecting conditions) was likely not performed or considered necessary by the FDA for this 510(k) clearance due to the nature of the device as an X-ray detector and the comparison to a predicate.

    Therefore, many of the requested details about a study proving device performance against acceptance criteria for diagnostic capability cannot be extracted from this document, as such a study does not appear to be the basis for this 510(k) clearance. The "acceptance criteria and reported device performance" primarily relate to technical specifications and equivalence.

    However, I can extract information regarding technical performance metrics and how they compare between the proposed device and the predicate. These comparisons serve as the "evidence" for substantial equivalence.

    Here's the breakdown based on the provided text, focusing on the technical and non-clinical aspects:


    1. Table of Acceptance Criteria and Reported Device Performance

    The document does not explicitly present "acceptance criteria" in the format of a clinical performance study. Instead, it compares the technical specifications and performance characteristics of the proposed device (Mars1717X) to its predicate (Mars1717V-VSI). The "acceptance criteria" can be inferred as being at least equivalent to or better than the predicate device for relevant technical specifications to demonstrate substantial equivalence.

    Biological EvaluationComplies with ISO 10993-1Complies with ISO 10993-1YesMaterials contacting skin are safe.

    Regarding a "study that proves the device meets the acceptance criteria":

    For this 510(k) submission, the "study" is a comparative technical performance assessment against a legally marketed predicate device (K201043). The conclusion of substantial equivalence means the device meets the regulatory "acceptance criteria" for market clearance based on this comparison. The non-clinical studies performed were used to demonstrate that changes in panel size, structure, IP grade, and surface pressure do not raise new questions of safety or effectiveness and that the performance is substantially equivalent to or better than the predicate.

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

    • Sample Size: Not applicable in the context of a clinical test set for diagnostic accuracy, as no such clinical study appears to have been conducted for this 510(k). The "test set" would be the device itself undergoing various engineering and performance tests (e.g., DQE measurements, spatial resolution charts, durability tests). The document does not specify the number of units tested.
    • Data Provenance: The technical performance data (DQE, spatial resolution, etc.) would be generated from laboratory tests conducted by the manufacturer, iRay Technology Taicang Ltd., in China.

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

    • Not applicable, as no clinical test set with human diagnostic ground truth was used for this 510(k) clearance based on the provided document.

    4. Adjudication Method for the Test Set:

    • Not applicable, as no clinical test set requiring expert adjudication was used.

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

    • No, a MRMC comparative effectiveness study was not performed according to this document. The submission focuses on technical equivalence to a predicate X-ray detector, not on the diagnostic effectiveness of human readers using the device with and without AI assistance.

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

    • Yes, the evaluation is inherently a standalone performance assessment of the device itself (the flat panel detector) in terms of its image acquisition capabilities (spatial resolution, DQE, etc.). There is no AI algorithm being evaluated for diagnostic assistance in this context. The device's performance is measured objectively based on physical and technical specifications, independent of human interpretation.

    7. Type of Ground Truth Used:

    • For the technical performance aspects, "ground truth" refers to objective physical measurements and standards. For example:
      • Spatial resolution is measured using phantoms or line pair gauges with known patterns.
      • DQE is measured according to standardized protocols (e.g., IEC 62220-1) using known X-ray spectra and dose levels.
      • Durability (surface pressure, IP rating) is tested against engineering specifications and industry standards.
      • Safety (electrical, biological) is assessed against international standards (e.g., IEC 60601-1, ISO 10993-1).

    8. Sample Size for the Training Set:

    • Not applicable, as this is not an AI/machine learning device requiring a training set in the conventional sense. The "training" in manufacturing would refer to quality control and calibration processes during production.

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

    • Not applicable, as there is no training set in the context of an AI algorithm.

    AI/ML Overview

    The provided text is a 510(k) summary for a medical device (Wireless Digital Flat Panel Detector). It describes the device, its intended use, and comparison to a predicate device to demonstrate substantial equivalence. However, it does not contain information about a study proving the device meets specific acceptance criteria based on diagnostic performance (e.g., sensitivity, specificity, accuracy).

    The document focuses on demonstrating substantial equivalence primarily through technical characteristics, safety, and non-clinical performance, rather than clinical diagnostic accuracy or reader performance studies.

    Therefore, most of the information requested in your prompt regarding acceptance criteria and studies to prove diagnostic performance (points 1-7, and 9 for the test set) cannot be extracted from this document. The document explicitly states: "clinical consideration may not necessary for changes in the pixel size and resolution with the same x-ray detection material and may not necessary for changes in the wireless functionality if non-clinical information is sufficient to support the substantial equivalence." This indicates that a detailed clinical performance study as you've described was not deemed necessary for this 510(k) submission.

    Here's what can be extracted based on the provided text:

    Preamble: This 510(k) submission for the Wireless Digital Flat Panel Detector (Models: Mars1717V-VSI, Mano4343W) focuses on demonstrating substantial equivalence to a predicate device (Mars1717XF-CSI, K183713) based on technical, electrical, mechanical, and non-clinical performance characteristics, rather than a clinical study evaluating diagnostic accuracy or human reader performance. Therefore, detailed information on diagnostic performance acceptance criteria, sample sizes for such studies, expert involvement for ground truth, or MRMC studies is not present.

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

    • Sample Size: Not applicable/Not specified for diagnostic performance tests. The evaluation was primarily based on technical specifications and non-clinical considerations. The statement "There was no significant difference between the images of the Mars1717V-VSI/Mano4343W and those of the predicate device" implies some form of image comparison, but no formal test set size or study methodology is detailed.
    • Data Provenance: Not applicable for diagnostic test set; the document describes a technical and safety comparison.

    AI/ML Overview

    The provided text is a 510(k) summary for the iRay Technology Taicang Ltd. Wireless Digital Flat Panel Detectors (Models Mars1417V-TSI, Mano4336W). This document does not contain details about acceptance criteria, a specific study proving the device meets those criteria, or clinical performance data in the context of diagnostic accuracy. These types of studies (like MRMC or standalone performance evaluations with ground truth) are typically required for AI-powered diagnostic devices, which this is not.

    This document focuses on establishing substantial equivalence to a predicate device (Mars1417XF-CSI, K182551) based on non-clinical performance characteristics, safety, and technological characteristics, rather than clinical performance for diagnostic tasks.

    Therefore, most of the requested information regarding acceptance criteria, study details, sample sizes, expert qualifications, and ground truth establishment for diagnostic accuracy cannot be extracted from this document.

    Here's a breakdown of what can and cannot be answered based on the provided text:

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

    The document does not explicitly state acceptance criteria for diagnostic performance or present a table comparing such criteria to reported diagnostic performance. It focuses on technical specifications and safety standards.

    Biological EvaluationAssured safety (ISO 10993-1)Evaluation results and test results assured safety the same as the predicate device

    2. Sample sized used for the test set and the data provenance (e.g. country of origin of the data, retrospective or prospective)

    This information is not provided in the document. The substantial equivalence argument relies on non-clinical performance and safety testing, not on a clinical test set for diagnostic accuracy with patient data.

    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 provided because there was no clinical diagnostic performance study described. The document is about the technical specifications and safety of the X-ray detector, not an AI or diagnostic algorithm that requires expert ground truth.

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

    This information is not provided as there was no clinical diagnostic performance study described.

    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 such study is mentioned or implied in this 510(k) summary. This device is a digital flat panel detector, a hardware component for X-ray imaging, not an AI-assisted diagnostic software.

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

    No standalone diagnostic algorithm performance study is mentioned. This device is a digital flat panel detector, not a diagnostic algorithm.

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

    Not applicable, as no clinical diagnostic performance study with ground truth was described.

    8. The sample size for the training set

    Not applicable, as this device is a hardware component and not an AI/ML algorithm that requires a training set of imaging data.

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

    Not applicable, as this device is a hardware component and not an AI/ML algorithm that requires a training set with established ground truth.

    In summary: The provided 510(k) summary is for an X-ray detector, a hardware device. The equivalence argument is based on technical specifications, electrical safety, EMC testing, and biological evaluation, comparing it to a legally marketed predicate device. It does not involve AI/ML components or clinical diagnostic accuracy studies that would require the establishment of ground truth by experts from a sample of patient data. Therefore, most of the questions regarding clinical study design for diagnostic performance cannot be answered from this document.

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

    The document does not explicitly present a table of "acceptance criteria" for clinical performance as would be seen for an AI-powered diagnostic device. Instead, it focuses on demonstrating substantial equivalence by comparing the technical specifications of the proposed device to the predicate device. The implicit "acceptance criteria" here are that the performance metrics of the proposed device are comparable to or better than the predicate device, or within acceptable tolerances for the intended use.

    Here's a table focusing on the comparative technical specifications presented, which serve as the "performance" data for establishing equivalence:

    ItemPredicate Device: Mars1417XF-GSI Wireless Digital Flat Panel DetectorProposed Device: Mars1717XF-GSI Wireless Digital Flat Panel Detector
    Functional/Technical Specs

    Performance Metrics
    Image Matrix Size:2336 × 2836 pixels2832 × 2836 pixels
    Pixel Pitch:150μmSame (150μm)
    Effective Imaging Area:350.4 mm × 425.4 mm424.8 mm × 425.4 mm

    Detective Quantum Efficiency (DQE) (RQA5, 3.2µGy)0.22 at 1 lp/mm0.23 at 1 lp/mm
    Power Consumption:Max. 19WMax. 20W
    Dimensions:384 mm × 460 mm × 15 mm460 mm × 460 mm × 15 mm

    Note: The primary difference highlighted and addressed in the document is the "panel dimension" which impacts "Image Matrix Size," "Effective Imaging Area," "MTF," "DQE", "Power Consumption", and "Dimensions". The submission argues that non-clinical information is sufficient to support substantial equivalence despite these changes.

    2. Sample size used for the test set and the data provenance (e.g. country of origin of the data, retrospective or prospective)

    The document describes non-clinical testing rather than a clinical study with a "test set" of patient data in the typical sense of AI/diagnostic device trials (i.e., analyzing images of patients to assess diagnostic accuracy). The "study" here refers to:

    • Electrical Safety and EMC testing: Performed according to IEC/ES 60601-1 and IEC/EN 60601-1-2.
    • Biological Evaluation: Evaluated with ISO 10993-1 for materials contacting operators' skin.
    • Non-clinical Considerations: Performance comparisons, likely quantitative measurements of detector characteristics (MTF, DQE, spatial resolution), and electromagnetic compatibility. This would involve a sample of the manufactured devices, not patient data.
    • Clinical Consideration: The submission states that a clinical consideration (study with patient data) was not necessary because the modification from the predicate device to the proposed device is primarily the "panel dimension." It claims "non-clinical information is sufficient to support the substantial equivalence."

    Therefore, there is no patient-based "test set" sample size or data provenance (country, retrospective/prospective) relevant to clinical performance assessment mentioned because a clinical study was explicitly deemed unnecessary by the manufacturer, and presumably accepted by the FDA for this direct predicate comparison.

    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)

    Since no clinical study with a patient imaging test set was conducted (as per point 2), there were no experts used to establish ground truth for a clinical test set. The ground truth in this submission is established through:

    • Standardized technical measurements: For parameters like MTF, DQE, spatial resolution, which are objective physical properties of the detector.
    • Compliance with international standards: For electrical safety, EMC, and biological compatibility.

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

    Not applicable, as no patient-based clinical "test set" requiring adjudication of diagnoses was used.

    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

    Not applicable. This device is a digital flat panel detector (hardware), not an AI-powered diagnostic software. Its purpose is to capture X-ray images, not to interpret them or assist human readers in diagnosis. Therefore, no MRMC study or AI assistance evaluation was performed.

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

    Not applicable, as this is a hardware device (X-ray detector), not a standalone algorithm.

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

    As explained in point 3, the "ground truth" for the performance evaluation in this 510(k) submission is based on:

    • Objective physical measurements (e.g., MTF, DQE, spatial resolution) using phantoms and calibrated equipment.
    • Adherence to international safety and performance standards (e.g., IEC/ES 60601-1, IEC/EN 60601-1-2, ISO 10993-1).
    • Demonstration of equivalence to a legally marketed predicate device based on these technical and safety characteristics.

    8. The sample size for the training set

    Not applicable. This is a hardware device, not an AI model that requires a training set of data.

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

    Not applicable, as there is no training set for a hardware device.

    Intended Use

    Mars1417XF-CSI Wireless Digital Flat Panel Detector is indicated for digital imaging solution designed for providing general radiographic diagnosis of human anatomy. It is intended to replace radiographic film/screen systems in all general-purpose diagnostic procedures. This device is not intended for mammography or dental applications.

    Device Description

    Mars1417XF-CSI Wireless Digital Flat Panel Detector is a kind of wireless digital flat panel detector. It supports the single frame mode, with the key component of TFT/PD image sensor flat panel of active area: 35.04cm×42.54cm.

    The sensor plate of Mars1417XF-CSI Wireless Digital Flat Panel Detector is direct-deposited with CsI scintillator to achieve the conversion from X-ray to visible photon. The visible photons are transformed to electron signals by diode capacitor array within TFT panel, which are composed and processed by connecting to scanning and readout electronics, consequently to form a panel image by transmitting to PC through the user interface.

    The major function of the Mars1417XF-CSI Wireless Digital Flat Panel Detector is to convert the X-ray to digital image, with the application of high resolution X-ray imaging. This detector is the key component of DR system, enables to complete the digitalization of the medical X-ray imaging with the DR system software.

    AI/ML Overview

    The provided text describes a 510(k) submission for a Wireless Digital Flat Panel Detector (Mars1417XF-CSI). It focuses on establishing substantial equivalence to a predicate device rather than providing acceptance criteria and a detailed study proving the device meets them as a standalone AI/diagnostic device.

    The document outlines performance characteristics of the detector itself (e.g., DQE, MTF, spatial resolution) and a "concurrence study" using phantom images, but this is not a clinical study to validate a diagnostic AI or to show human performance improvement.

    Therefore, for AI/diagnostic device validation, much of the requested information (like specific acceptance criteria for diagnostic performance, details on test set ground truthing by experts, MRMC studies, or training set details) is not present in the provided text, as this device is a hardware component (a digital X-ray detector).

    However, I can extract the relevant information regarding the device's technical specifications and the "concurrence study," and highlight what information isn't available for aspects typically associated with AI/diagnostic device validation.

    Here's the breakdown based on the provided text:


    Device: Wireless Digital Flat Panel Detector (Mars1417XF-CSI)
    Device Type (as per 510(k)): Stationary x-ray system component (Product Code: MQB)
    Purpose: Digital imaging solution for general radiographic diagnosis of human anatomy, replacing film/screen systems. Not an AI diagnostic device.


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

    The document frames "acceptance criteria" through comparison with a predicate device and established technical parameters for X-ray detectors. It doesn't list explicit pass/fail criteria for clinical diagnostic performance but rather demonstrates comparability of technical specifications.

    Notes: The "acceptance criteria" here are implicitly meeting the FDA 510(k) standard of substantial equivalence to a predicate device by demonstrating comparable technical performance and safety. The study is not a diagnostic performance study validating an AI algorithm.


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

    • Test Set Size: 30 images
    • Data Provenance: The images were described as "Phantom images." The origin (country, retrospective/prospective clinical data) is not specified, as this was a technical performance comparison using phantoms, not clinical data.

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

    • This information is not provided as the "concurrence study" used phantom images and focused on the technical image quality comparison, not diagnostic interpretation by human experts to establish ground truth for a diagnostic AI. The statement "No significant difference between the images" implies a qualitative assessment, but details on assessors (number or qualifications) are absent.

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

    • Not applicable / Not provided. Given it was a "concurrence study" of phantom images, detailed adjudication methods for human diagnostic interpretation are not relevant or described.

    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 performed. This device is a digital X-ray detector, not an AI-powered diagnostic tool, so a study comparing human reader performance with and without AI assistance is beyond the scope of this 510(k) submission for a hardware component.

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

    • Not applicable. This submission is for an X-ray detector, not a diagnostic algorithm. Therefore, a standalone algorithm performance study was not conducted.

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

    • The ground truth for the "concurrence study" was based on phantom images and comparison to the predicate device's image output, not clinical ground truth like pathology or patient outcomes. The study aimed to demonstrate technical equivalence in image generation.

    8. The sample size for the training set

    • Not applicable / Not provided. Given this is a hardware device (X-ray detector) and not an AI algorithm, there is no "training set" in the context of machine learning. The device's calibration and manufacturing processes would ensure its performance.

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

    • Not applicable / Not provided. As there is no AI training set, there is no ground truth establishment for such a set.
