Cardiovascular assessment by imaging photoplethysmography - a review

Biomed Tech (Berl). 2018 Oct 25;63(5):617-634. doi: 10.1515/bmt-2017-0119.


Over the last few years, the contactless acquisition of cardiovascular parameters using cameras has gained immense attention. The technique provides an optical means to acquire cardiovascular information in a very convenient way. This review provides an overview on the technique's background and current realizations. Besides giving detailed information on the most widespread application of the technique, namely the contactless acquisition of heart rate, we outline further concepts and we critically discuss the current state.

Keywords: camera; cardiovascular; heart rate; imaging photoplethysmography; oximetry; perfusion; remote photoplethysmography.
