Premarket evidence — what FDA accepted
source quote (p.7)
“The purpose of this Traditional 510(k) Pre-Market Notification is to introduce the change in AutoMeasure V3 software application onto the EPIQ Series Diagnostic Ultrasound Systems and Affiniti Series Diagnostic Ultrasound Systems. Since this is a software-only change and no new hardware was added, no acoustic output, cleaning and disinfectants, thermal, electrical, electromagnetic, and mechanical safety testing were required.”
source quote (p.10)
“Auto Measure is an optional software feature on the EPIQ Series Diagnostic Ultrasound System that provides the end user with semiautomated adult echocardiography 2D, Doppler or M-mode measurements through an AI-algorithm, training via machine-learning techniques. AutoMeasure V3 is created semi-automatically using machine learning algorithm without user interaction. Semi-automated adult echocardiography 2D, Doppler and M-mode measurements are generated using an artificial intelligence (AI) detection algorithm without user interaction.”

Reported performance (0 observations)
FDA source did not state a quantitative performance metric — non-reporting is itself the signal.
Each value carries its own analysis unit and task — never compare or pool across devices. Source: 510(k) summary PDF.

Recall and MAUDE counts are product-code-level (reports aren't reliably attributable to one device). Signals are descriptive observables with sources — never a judgment that the device is unsafe or drifting. Snapshot 2026-07-08.
