Koninklijke Philips N.V. Blood Perfusion Imaging Device Patent US12599310B2
Summary
USPTO granted Patent US12599310B2 to Koninklijke Philips N.V. on April 14, 2026, covering a device, method, and systems for imaging blood perfusion by combining widefield imaging and radial imaging to estimate signal source depth. The patent names Willem Verkruijsse, Mark Josephus Henricus van Gastel, and Age Jochem van Dalfsen as inventors, with an application filed December 7, 2021. The technology addresses signal ambiguity in existing photoplethysmography and speckle contrast perfusion imaging systems by providing more accurate combined imaging.

What changed
USPTO granted Patent US12599310B2 to Koninklijke Philips N.V. for a device and system that combines widefield imaging and radial imaging to estimate the source depth of blood perfusion signals, improving accuracy over existing photoplethysmography and speckle contrast techniques. The patent contains 15 claims covering the imaging device, associated systems, and methods for blood perfusion assessment.
Medical device manufacturers and healthcare technology companies developing perfusion monitoring systems should note this patent's claims regarding combined imaging modalities for reduced signal ambiguity. Competitors in the blood perfusion imaging space should review their existing intellectual property portfolios for potential conflicts with the claimed combination of widefield and radial imaging approaches.

Device, method and systems for providing imaging of one or more aspects of blood perfusion

Abstract
The present invention relates to a device (100), systems (500, 500′, 500″) and a method for providing imaging of one or more aspects of blood perfusion induced by cardiac induced blood motion in a skin region (12) of a subject. Current perfusion imaging systems use either photoplethysmography (PPG) or speckle contrast (SC), but a problem of both techniques is that considerable ambiguity exists because the source of the signal (volume pulsatility in PPG or blood flow in SC) is unknown. The present invention is based on the idea of combining two different types of measurement, namely widefield imaging and radial imaging, in order to estimate the source depth (20) of the signal to provide more accurate PPG imaging and SC imaging.
