AI/ML Overview

The provided text describes a 510(k) summary for the GE LOGIQ 700 diagnostic ultrasound system, not a study proving device performance against acceptance criteria. A 510(k) submission primarily demonstrates substantial equivalence to a legally marketed predicate device, rather than providing detailed clinical study results with specific acceptance criteria and performance metrics typically seen in studies for novel high-risk devices or AI/ML-driven diagnostics.

Therefore, many of the requested elements for a study proving device performance against acceptance criteria are not available in this document.

However, I can extract information related to the device's intended use and the nature of the submission.

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

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

Not applicable/Not available. This document is a 510(k) summary demonstrating substantial equivalence to a predicate device. It does not contain specific performance metrics with acceptance criteria for a clinical study comparing the device's diagnostic accuracy against a ground truth. The submission confirms the device has been evaluated for "acoustic output, biocompatibility, and thermal, electrical and mechanical safety" and found to conform with applicable medical device safety standards, but no comparative performance data is presented.

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/Not available. No clinical test set or data provenance is mentioned as this is a 510(k) for substantial equivalence, not a performance study.

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/Not available. No ground truth establishment or expert involvement for a test set is discussed in this 510(k) summary.

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

Not applicable/Not available. No test set or adjudication method is discussed.

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/Not available. This device is a diagnostic ultrasound system from 1997, predating widespread AI/ML integration in such systems. No MRMC study or AI assistance is mentioned.

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

Not applicable/Not available. This is a hardware/software system, not an algorithm-only device.

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

Not applicable/Not available. No ground truth is discussed in the context of a performance study for this 510(k) summary.

8. The sample size for the training set

Not applicable/Not available. This document describes a traditional medical device, not an AI/ML system requiring a training set in the modern sense.

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

Not applicable/Not available. See point 8.
