This document describes a 510(k) premarket notification for the DC-8/DC-8 PRO/DC-8 CV/DC-8 EXP/DC-8S Diagnostic Ultrasound System. This type of submission is a statement to the FDA that the device is substantially equivalent to another legally marketed device, not a claim of superior performance or a detailed study of acceptance criteria against novel performance metrics.

Therefore, the provided text does not contain the acceptance criteria or a study proving the device meets those criteria in the context of specific performance metrics for diagnosis or improved human reader performance with AI assistance. Instead, it focuses on demonstrating substantial equivalence to predicate devices and adherence to general safety and performance standards.

Here's an analysis of the provided information relative to your requested points:

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

This information is not provided in the document. The 510(k) summary focuses on demonstrating substantial equivalence to predicate devices and compliance with recognized safety and performance standards, rather than defining specific outcome-based acceptance criteria and reporting performance against them.

2. Sample size 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 as there is no clinical performance study detailed in this 510(k) summary. The document states "DC-8/DC-8 PRO/DC-8 CV/DC-8 EXP/DC-8S Diagnostic Ultrasound System has been evaluated for acoustic output, biocompatibility, cleaning and disinfection effectiveness as well as thermal, electrical and mechanical safety." These are non-clinical hardware tests, not clinical performance studies involving a test set of 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 applicable/not provided. As no clinical performance study is detailed, there's no mention of a test set, ground truth establishment, or experts for that purpose.

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

This information is not applicable/not provided. No clinical performance study or test set requiring adjudication is 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

An MRMC comparative effectiveness study was not done, and there is no mention of AI assistance in this document. The device is a general-purpose diagnostic ultrasound system, not explicitly an AI-powered diagnostic tool. The purpose of this 510(k) is to establish substantial equivalence, not to demonstrate improved human reader performance.

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

This information is not applicable/not provided. The device is a diagnostic ultrasound system, which inherently involves human operation and interpretation. There is no mention of a standalone algorithm or AI performance.

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

This information is not applicable/not provided. Since no clinical performance study with a test set is detailed, there's no mention of the type of ground truth used.

8. The sample size for the training set

This information is not applicable/not provided. The device is an ultrasound system. There is no mention of a "training set" in the context of an algorithm or AI.

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

This information is not applicable/not provided. As there's no training set mentioned in the context of an algorithm or AI, there's no corresponding information on how ground truth would be established for it.

The conclusion states that the "Intended uses and other key features are consistent with traditional clinical practices, FDA guidelines and established methods of patient examination. The design, development and quality process of the manufacturer confirms with 21 CFR 820, ISO 9001 and ISO 13485 quality systems. The device conforms to applicable medical device safety standards. Therefore, the M7/M7T Diagnostic Ultrasound System is substantially equivalent with respect to safety and effectiveness to devices currently cleared for market."

This heavily implies that due to the nature of the device (a general-purpose ultrasound system) and the regulatory pathway chosen (510(k) substantial equivalence), the "study" demonstrating its meeting of acceptance criteria consists of:

• Verification and validation against engineering and safety standards (as listed above).
• Bench testing and performance verification to ensure the device functions as intended (e.g., imaging modes, frequency ranges).
• Comparison of its intended uses and technological characteristics to already cleared predicate devices.

There is no mention of a clinical trial or a study assessing the diagnostic accuracy or efficacy of the M7/M7T Diagnostic Ultrasound System in this summary. Such studies are typically not required for general-purpose ultrasound systems cleared via the 510(k) pathway when substantial equivalence to existing devices is established based on technical and functional similarities and adherence to recognized standards.
