IMEXLAB 9100 Diagnostic Ultrasound Device

The provided document is a 510(k) premarket notification approval letter for the IMEXLAB 9100 Diagnostic Ultrasound Device, dated April 15, 1998. It primarily focuses on regulatory approval and indications for use, and does not contain information about specific acceptance criteria or a study proving the device meets those criteria, as typically seen in modern AI/ML device submissions.

Therefore, I cannot provide the requested information in the format of acceptance criteria and reported device performance. The details you're looking for (sample sizes, expert qualifications, adjudication methods, MRMC studies, effect sizes, standalone performance, ground truth types, training set details) are characteristic of recent regulatory submissions for AI-powered medical devices, which involve rigorous performance testing.

The document indicates that the IMEXLAB 9100 was found "substantially equivalent" to legally marketed predicate devices prior to May 28, 1976. This means its regulatory approval relied on demonstrating that it performs as safely and effectively as existing, legally marketed ultrasound devices for its stated indications: "assisting in the detection of peripheral vascular diseases."

No study data, performance metrics, or specific acceptance criteria are detailed in this regulatory approval letter. Such information would typically be found in the manufacturer's 510(k) submission itself, not in the FDA's approval letter, especially for devices cleared via substantial equivalence over two decades ago.
