source quote (p.5)
“The purpose of this Traditional 510(k) Pre-Market Notification is to introduce the Auto ElastQ software feature onto the EPIQ and Affiniti Series Diagnostic Ultrasound Systems.”
AlgorithmThe Auto ElastQ software feature is intended to assist the user in making liver stiffness measurements using 2D-SWE in the liver by recommending specific frames and ROI positions to the user. The system software will select up to three frames that are assessed to be the most stable and present these to the user. The circle ROI will be launched in the locations that are identified to be homogenous and temporally stable.

    recall event 97217 (openFDA)

Recall and MAUDE counts are product-code-level (reports aren't reliably attributable to one device); a recall is shown as device-attributed only when the recall record itself lists this clearance number. Signals are descriptive observables with sources — never a judgment that the device is unsafe or drifting. Snapshot 2026-07-08.

Reimbursement — how devices like this got paid

Not yet tracked — no payment pathway indexed for this clearance (the reimbursement corpus is a growing seed set).

Applicable FDA guidance — what the submission is measured against

FDA guidance documents and guiding principles applicable to 510(k) AI/ML devices in the Radiology panel. A curated reference index, not legal or regulatory advice — each item states its own status, and a draft is never binding.

Applicability is derived from the device's FDA advisory panel and pathway — cross-cutting guidances apply to every AI/ML device; panel-specific ones are flagged. Titles, dates, and links verified against fda.gov as of July 2026.
