Premarket evidence — what FDA accepted

Device typehardware with ml
source quote (p.5)
“The Philips Lumify Diagnostic Ultrasound System (Lumify) is a mobile, durable, and reusable, software-controlled medical device, which is intended to acquire high-resolution ultrasound data and to display the data in B (2D), Pulsed Wave Doppler, Color Doppler, Combined (B+ Color), and M modes. The Expanded B-lines Software Feature, with the updated merged B-line detection feature, uses machine learning as part of the algorithm design.”
Algorithmmachine learning classifier
source quote (p.7)
“The Expanded B-lines Software Feature, with the updated merged B-line detection feature, uses machine learning as part of the algorithm design. Relevant image features extracted from a lung ultrasound cine loop are provided to a machine learning classifier that identifies B-lines and/or merged B-lines in each frame.”
Adaptive (vs locked)No
source quote (p.7)
“The algorithm, that used artificial intelligence/machine learning in its development, is locked (meaning no further adjustments by the algorithm are made and it does not continue to learn once commercialized).”
PCCPNo
Cybersecurity addressedNo

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.
