Acceptance Criteria and Device Performance

The document describes the Siemens SC2000/X300 Diagnostic Ultrasound System and its various transducers. The acceptance criteria essentially focus on demonstrating substantial equivalence to previously cleared devices. The "reported device performance" is implicitly that the device performs equivalently to the predicate devices and meets safety and performance standards.

1. Table of Acceptance Criteria and Reported Device Performance

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

The document explicitly states: "Since the modified devices use the same technology and principles as existing devices, clinical data is not required." This indicates that no clinical test set with human patients was used specifically for this 510(k) submission. The evaluation was based on nonclinical tests and comparison to predicate devices. Therefore, there is no sample size, country of origin, or information on retrospective/prospective data for a clinical test set.

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

As there was no clinical test set for this 510(k) submission, there is no mention of experts used to establish ground truth for a test set. The review focused on engineering and performance standards, and comparison to previously cleared devices.

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

Not applicable, as no clinical test set 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. The document describes a diagnostic ultrasound system and its transducers, not an AI-assisted diagnostic tool. No MRMC study or AI performance evaluation is mentioned.

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

Not applicable. This device is a diagnostic ultrasound system, not a standalone algorithm.

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

For the nonclinical tests conducted, the "ground truth" would be established by the specifications and performance metrics outlined in the various referenced safety and performance standards (e.g., UL 60601-1, IEC 60601-2-37, etc.). For the substantial equivalence claim, the ground truth is the performance and safety profiles of the predicate devices.

8. The sample size for the training set

Not applicable, as this is a traditional diagnostic ultrasound system, not an AI/ML-based device requiring a training set.

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

Not applicable, as no training set was used.

The ultrasound imaging systems are intended for the following applications: Fetal, Abdominal, Intraoperative, Pediatric, Small Parts, Transcranial, OB/GYN, Cardiac, Pelvic, Neonatal/Adult Cephalic, Vascular, Musculoskeletal, Superficial Musculoskeletal, and Peripheral Vascular applications.

The system also provides the ability to measure anatomical structures {fetal, abdominal, intraoperative, pediatric, small organ, neonatal cephalic, adult cephalic, cardiac, trans-esophageal, transvaginal, peripheral vessel, musculo-skeletal (conventional), musculo-skeletal (superficial) and neonatal cardiac) and calculation packages that provide information to the clinician that may be used adjunctively with other medical data obtained by a physician for clinical diagnosis purposes.

The Arterial Health Package (AHP) software provides the physician with the capability to measure Intima Media Thickness and the option to reference normative tables that have been validated and published in peerreviewed studies. The information is intended to provide the physician with an easily understood tool for communicating with patients regarding state of their cardiovascular system.

This document is a 510(k) Pre-market Notification for a diagnostic ultrasound system. It primarily focuses on demonstrating substantial equivalence to a predicate device rather than presenting a study to prove acceptance criteria for a new AI-based device. Therefore, much of the requested information regarding "acceptance criteria" for AI performance simply isn't present in this type of submission.

However, I can extract information related to the device's technical characteristics and how its equivalence was established.

Analysis of the Provided Text:

The document describes the Acuson S1000, S2000, S3000 Diagnostic Ultrasound Systems manufactured by Siemens Medical Solutions, Inc. The submission aims to demonstrate substantial equivalence to previously cleared versions of the same systems (K132804).

Key Findings relevant to your request, but with caveats:

• No specific "acceptance criteria" are defined for AI/algorithm performance. This submission is for an ultrasound system, not a specific AI algorithm. The closest it comes to a performance claim for a specific component is the "Arterial Health Package (AHP) software," which "provides the physician with the capability to measure Intima Media Thickness and the option to reference normative tables that have been validated in peer-reviewed studies." However, no acceptance criteria for this device's measurement capacity are presented, nor is there a study within this document proving the device meets them. The AHP feature itself relies on external, peer-reviewed studies for its normative tables, not on studies conducted for this 510(k) submission to validate the specific device's measurement accuracy against defined criteria.
• No "study that proves the device meets the acceptance criteria" is included for a novel AI component. The document explicitly states: "Since the S1000, S2000, S3000 systems use the same technology and principles as existing devices, clinical data is not required." This indicates that the submission relies on the established safety and effectiveness of the predicate devices and the underlying technology, not on new clinical trials or performance studies for novel features.
• "Device Performance" is inherently tied to being "substantially equivalent" to the predicate. The performance is deemed acceptable because it is demonstrably similar to a device already on the market.

Here's how I can address your points based on the provided text, heavily noting limitations:

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

As explained above, no specific quantitative acceptance criteria for algorithm performance are presented for this ultrasound system or its features. The core "acceptance criteria" in a 510(k) for a device like this are primarily related to safety, electrical safety, biocompatibility, and functional equivalence to a predicate device.

The "reported device performance" is essentially that it functions equivalently to the predicate device, offering various imaging modes, frequencies, and features, and meets relevant voluntary safety standards.

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

• Not applicable (N/A) for this submission. The document explicitly states: "Since the S1000, S2000, S3000 systems use the same technology and principles as existing devices, clinical data is not required." This implies that no new test set of patient data (clinical or image-based) was used to prove the device's performance against specific acceptance criteria. The submission relies on non-clinical engineering and safety tests and the established equivalence to the predicate device.

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)

• N/A. No test set requiring expert ground truth was described or presented in this 510(k). The clinical data requirement was waived due to substantial equivalence. The "Arterial Health Package (AHP) software" feature mentions "normative tables that have been validated in peer-reviewed studies," implying external expert validation for those tables, but not for its integration into this specific device as part of this submission.

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

• N/A. No test set requiring an adjudication method was described or presented.

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

• N/A. No MRMC study was performed or referenced. This is not an AI-assisted diagnostic device, but a diagnostic ultrasound system. Clinical data, including MRMC studies, was not required.

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

• N/A. This submission is for an ultrasound system, not a standalone algorithm. While it contains software (like the AHP), its performance is not evaluated as a standalone AI given the nature of the submission. The AHP's function is "to provide the physician with the capability to measure" and "reference normative tables," suggesting a human-in-the-loop scenario where the physician retains clinical diagnosis responsibility.

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

• N/A as a primary method for this submission. For establishing the safety and performance of the overall ultrasound system, the ground truth is primarily based on compliance with established engineering and safety standards and the known performance of the predicate device. For the AHP feature, its normative tables were based on "peer-reviewed studies," which would have their own ground truth (likely clinical data, pathology, or outcomes depending on the study) but this is not data directly generated or verified for this 510(k).

8. The sample size for the training set

• N/A. This submission does not describe a machine learning model requiring a training set.

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

• N/A. No training set for a machine learning model is mentioned in this submission.

Summary of the document's approach:

This 510(k) submission for the Acuson S1000, S2000, S3000 Diagnostic Ultrasound Systems relies on demonstrating substantial equivalence to existing, legally marketed predicate devices. This means that:

• The device uses the same technology and principles of operation as previously cleared devices.
• It has the same intended uses as the predicate.
• Any differences in technological characteristics do not raise new questions of safety or effectiveness.
• Non-clinical tests (acoustic output, biocompatibility, cleaning/disinfection, electrical/mechanical/thermal/EM safety, software validation, transducer/wireless performance) confirm compliance with recognized medical device safety standards.
• Clinical data (and thus specific "acceptance criteria" and studies to meet them for novel algorithmic performance) were explicitly deemed not required because the systems utilize established technology and principles.

Therefore, the requested information about acceptance criteria and studies to meet them, particularly concerning AI or complex algorithmic performance, is not present in this type of 510(k) submission which focuses on substantial equivalence for a general diagnostic imaging system.

This 510(k) summary for the ACUSON SC2000 Diagnostic Ultrasound System is a Special 510(k), indicating a minor change to a previously cleared device. Therefore, a comprehensive de novo clinical study demonstrating performance against acceptance criteria for a novel device is not part of this submission. Instead, the performance data section explicitly states: "No performance data required to support this modification, as there is no change to any hardware or software, or method of use."

The submission focuses on demonstrating substantial equivalence to a previously cleared device (K123622) by only renaming three transducers. As such, the typical elements of a study proving a device meets acceptance criteria (like a test set, ground truth, experts, and statistical results) are not provided in this document.

However, I can extract the acceptance criteria implied by this type of submission, which is the determination of substantial equivalence to the predicate device for the specified indications for use.

Here's a breakdown based on the provided document:

1. Table of Acceptance Criteria and Reported Device Performance

The V5Ms Transesophageal Transducer consists of a gastroscope control housing where nosepiece articulation and transducer rotation are controlled. A flexible transesophageal guide tube with a nosepiece containing the acoustic array extends from one end of the control housing and the system cable/connector extends from the other end. The acoustic array has 64 elements and rotates 180 degrees to provide imaging planes from transverse view to inverse transverse view. Rotation is powered by a motor in the control housing and is controlled by the operator using a switch button on the control housing for clockwise and counterclockwise rotation. Nosepiece articulation is achieved by manipulating a vertebrae section adjacent to the nosepiece through a series of control wires attached to knobs on the control housing. The nosepiece can be articulated in both the anterior/posterior and left/right directions.

Here's a breakdown of the requested information, based on the provided document:

Acceptance Criteria and Study Details for V5Ms Transesophageal Transducer

1. Table of Acceptance Criteria and Reported Device Performance

The provided 510(k) submission document does not explicitly state quantitative acceptance criteria or specific device performance metrics in the way one might expect for a new or significantly modified device. Instead, the submission relies heavily on substantial equivalence to a previously cleared predicate device (Siemens V5Ms Transesophageal Transducer, K052021). The key "performance data" presented is that "Performance data is not required for this modification as there is no change to software or hardware." This implies that the device is expected to perform identically to its predicate because the changes are limited to patient contact materials.

Therefore, the acceptance criteria are implicitly met by demonstrating that the modifications do not negatively impact the established performance of the predicate device.

Implicit Acceptance Criteria and Reported Performance (Based on Substantial Equivalence):

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

• Sample Size for Test Set: Not applicable (N/A). The document explicitly states, "Performance data is not required for this modification as there is no change to software or hardware." Therefore, there was no clinical performance test set used. The evaluation centered on non-clinical tests for biocompatibility and asserting substantial equivalence.
• Data Provenance: N/A for clinical performance data. For biocompatibility testing, the data would typically originate from a laboratory (likely in the USA or a facility that adheres to international standards like ISO). The origin is not specified beyond "Nonclinical tests contained in this submission include biocompatibility testing per ISO10993-1 (cytotoxicity, sensitization, irritation)."

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

• N/A. As no clinical performance test set was conducted, there was no need for experts to establish ground truth. The primary "experts" involved in the submission would be Siemens' own regulatory and engineering teams, and subsequently, FDA reviewers.

4. Adjudication Method for the Test Set

• N/A. Since no clinical performance test set was conducted, no adjudication method was used.

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

• No. No MRMC study was conducted. The submission is a 510(k) for substantial equivalence based on minor modifications (patient contact materials) to an existing device, not a new clinical effectiveness study.

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

• N/A. The device is a diagnostic ultrasound transducer, not an AI algorithm. Therefore, the concept of "standalone performance" in the context of an algorithm does not apply.

7. The Type of Ground Truth Used

• N/A for clinical effectiveness. For biocompatibility, the "ground truth" is defined by the ISO10993-1 standard for cytotoxicity, sensitization, and irritation. This involves standardized biological tests.

8. The Sample Size for the Training Set

• N/A. This device is a hardware component (transducer) and does not involve machine learning or AI, and therefore does not have a "training set."

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

• N/A. As there is no training set for this device, this question is not applicable.

Here's an analysis of the provided 510(k) summary regarding the Acuson SC2000™ Diagnostic Ultrasound System, focusing on acceptance criteria and study details.

Important Note: The provided document is a 510(k) Summary, which typically focuses on demonstrating substantial equivalence to a legally marketed predicate device rather than presenting detailed standalone performance studies with specific acceptance criteria and outcome metrics in the way a clinical trial for a new therapeutic device might. The "performance data" section in this type of submission generally refers to engineering verification and validation against internal specifications and relevant safety standards, rather than direct clinical performance in terms of diagnostic accuracy against a ground truth in a clinical setting.

Therefore, the answers below will reflect the information available in this type of regulatory document. Many of the requested details (like sample size for test sets, number of experts for ground truth, adjudication methods, MRMC studies, effect size, and training set information) are explicitly not present in a standard 510(k) premarket notification for an ultrasound system, as this is a device modification submission focusing on safety and technological equivalence.

1. Table of Acceptance Criteria and Reported Device Performance

As this is a 510(k) for a modification to an existing device, the "acceptance criteria" are primarily based on established safety and performance standards for diagnostic ultrasound systems, and the "reported device performance" is the device's demonstrated compliance with these standards and verification of its specifications.

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

The document does not specify a "test set" in the context of clinical performance evaluation (e.g., patient data for diagnostic accuracy). The performance data cited refers to engineering and safety testing. Therefore, there is no information provided regarding sample size for a clinical test set or data provenance (e.g., country of origin, retrospective/prospective clinical data).

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

Not applicable/Not provided. As stated above, this submission focuses on technical safety and performance validation against standards, not a clinical study requiring expert-established ground truth for diagnostic accuracy.

4. Adjudication Method for the Test Set

Not applicable/Not provided. No clinical test set or adjudication method is mentioned in the document.

5. If a Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study was done, and its effect size

No. The document does not mention any MRMC comparative effectiveness study, nor does it provide information on a human readers' improvement with or without AI assistance. This type of study is not common for 510(k) submissions of basic ultrasound system modifications.

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

No. The SC2000™ is a diagnostic ultrasound system, an imaging device operated by a human. It is not an AI algorithm intended for standalone diagnostic performance. The document describes the system's ability to acquire and display ultrasound data, and its "calculation packages" provide information to the clinician for diagnosis, implying human interpretation is always in the loop.

7. The Type of Ground Truth Used

For the safety and performance testing described, the "ground truth" is defined by the technical specifications for the device and the objective criteria outlined in the various international and national safety and performance standards (e.g., acoustic output measurements, electrical safety limits, biocompatibility standards). This is engineering and regulatory compliance ground truth, not clinical ground truth (like pathology results or patient outcomes) for diagnostic accuracy.

8. The Sample Size for the Training Set

Not applicable/Not provided. This submission describes an ultrasound imaging system, not a machine learning model that requires a training set.

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

Not applicable/Not provided. As there is no mention of a machine learning model or training set, the establishment of ground truth for such a set is not relevant to this submission.
