Clinical applications for imaging photoplethysmography

Abstract Most of the work related to imaging photoplethysmography (iPPG) has its focus on methodological developments. To date, only few investigations addressed clinical applications. This chapter reviews the clinical usability of the iPPG. We present a number of potential applications together with their clinical background and relevant works. Covered applications comprise iPPG's use for patient monitoring and diagnostic applications beyond patient monitoring, particularly based on iPPG's capability for two-dimensional analyses of cutaneous perfusion. Finally, we provide an outlook on future clinical use cases and required developments.
