The provided text describes specific features and functionalities of the GE Venue Fit ultrasound system but does not contain information about acceptance criteria, reported device performance, or a specific study proving it meets acceptance criteria as typically outlined for AI/CADe devices.

The document is a 510(k) Premarket Notification Submission for the Venue Fit ultrasound system. It primarily focuses on demonstrating substantial equivalence to a predicate device (K220848 Venue Fit) regarding general imaging capabilities, technological characteristics, safety, and effectiveness.

Here's what can be extracted and what is explicitly stated as not applicable:

1. A table of acceptance criteria and the reported device performance
Not provided in the document. The document focuses on performance testing in the context of safety and effectiveness, rather than specific diagnostic accuracy metrics.

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. The document states, "The subject of this premarket submission, Venue Fit, did not require clinical studies to support substantial equivalence." Therefore, there is no test set in the context of a clinical study for diagnostic performance.

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, as no clinical studies were required.

4. Adjudication method (e.g. 2+1, 3+1, none) for the test set
Not applicable, as no clinical studies were required.

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 document does not describe an AI/CADe device that assists human readers, nor does it present results from an MRMC study.

6. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done
Not applicable. The Venue Fit is a diagnostic ultrasound system, not a standalone algorithm. Its capabilities, like "Auto Volume Flow (AVF)" or "Bladder Volume Tool", are functionalities of the ultrasound system itself, not standalone AI algorithms with reported diagnostic performance metrics.

7. The type of ground truth used (expert consensus, pathology, outcomes data, etc.)
Not applicable, as no clinical studies requiring ground truth establishment were mentioned.

8. The sample size for the training set
Not applicable. The document does not describe a machine learning algorithm that would have a training set. The "Venue Fit" is a general-purpose diagnostic ultrasound system. While it has "semi-automated tools," the document does not detail their development or any AI-specific training sets.

9. How the ground truth for the training set was established
Not applicable, as there is no mention of a training set for an AI algorithm.

Summary of what is present:
