There is disclosed a system and method for measuring arterial and venous bloodpulsewaveforms (BPWs) of a subject utilizing photoplethysmography (PPG). In anembodiment, thesystem and method comprises: providing a plurality of virtual sensorspositioned to cover adesired field-of-view of the subject, each virtual sensor adapted to detectand measure a BPWsignal from an area of the subject's body and provide a BPW signal output；processing the BPWsignal outputs of the plurality of virtual sensors to compare the BPWs atmultiple areas of thesubject's body to perform spatial perfusion analysis； and displaying at leastone aggregate outputbased on the spatial perfusion analysis. At least one aggregate output mayinclude a visualizationof one or more perfusion patterns overlaid on a photographic image of thesubject, and aggregatestatistics including subject heart rate and breathing rate. The system andmethod may use a signalfrom one of the virtual sensors as a reference waveform for cardiovascularmonitoring in thegeneration of parametric maps for assessing BPW characteristics at variousparts of the bodysimultaneously. The system and method may also include a contactphotoplethysmography(PPG) sensor, which is connected to the DSP and provides a BPW as a referencewaveform forimproved cardiovascular monitoring in the generation of parametric maps forassessing BPWcharacteristics at various parts of the body simultaneously.
