AI/ML Overview

The provided text is a 510(k) Premarket Notification from the FDA, which focuses on demonstrating substantial equivalence to a predicate device rather than presenting a detailed study proving performance against specific acceptance criteria for a new, innovative device.

Therefore, much of the requested information regarding detailed acceptance criteria, specific study design, sample sizes, expert qualifications, and ground truth establishment for performance claims cannot be found in this document.

The document primarily states that the device is "substantially equivalent" to predicate devices, and relies on non-clinical tests (safety, electrical, etc.) and design similarities to justify this claim. It explicitly states: "The subject of this premarket submission, Vivid T9/Vivid T8, did not require clinical studies to support substantial equivalence."

Below is a table summarizing the information that could be extracted from the provided text, and noted where information is explicitly not available or not applicable based on the content.

Study Details

Sample size used for the test set and the data provenance: Not applicable. The document explicitly states: "The subject of this premarket submission, Vivid T9/Vivid T8, did not require clinical studies to support substantial equivalence." Therefore, no "test set" in the context of clinical performance evaluation is described. The non-clinical tests (acoustic, electrical, thermal, etc.) inherently involve testing of the device itself rather than patient data.
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 requiring expert ground truth was performed for substantial equivalence.
Adjudication method (e.g., 2+1, 3+1, none) for the test set: Not applicable, as no clinical test set requiring adjudication was performed.
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 pertains to a general-purpose ultrasound system without specific mention of AI features that would necessitate an MRMC study for improved human reader performance. The "Clarity +" feature is described as "real-time image processing/filtering technique," not an AI-driven diagnostic aid that would directly impact human reader performance in a quantifiable way for this type of submission.
If a standalone (i.e. algorithm only without human-in-the-loop performance) was done: Not applicable. The device is an ultrasound system, not a standalone algorithm. Its "Clarity +" feature is an image processing technique integrated into the system, not a separate diagnostic algorithm.
The type of ground truth used (expert consensus, pathology, outcomes data, etc.): Not applicable for a clinical performance evaluation, as no clinical studies were deemed necessary. For the non-clinical tests (e.g., safety, electrical, acoustic), the "ground truth" is adherence to recognized performance standards and internal quality assurance measures.
The sample size for the training set: Not applicable. As this device did not require clinical studies, there is no mention of a "training set" for algorithm development related to diagnostic performance.
How the ground truth for the training set was established: Not applicable, as no training set for diagnostic algorithm development is mentioned or required in this submission.
