USPTO Abstract
In one aspect, embodiments disclosed herein relate to multi-sensor imaging systems for generating a pulsatile blood perfusion map, comprising a high accuracy blood flow sensor (702; 802) configured to generate a reference blood volume waveform at a reference site of a patient's body (706; 806), one or more low accuracy blood flow sensors (704; 804) configured to simultaneously generate a second blood volume waveform at any region of interest of the patient's body (708; 808), and a controller. The high accuracy blood flow sensor (702; 802) is a pulse oximeter and the one or more low accuracy blood flow sensors (704; 804) are one or more camera sensors each equipped with an optical filter.
