Imaging PPG (iPPG) focuses on the measurement of volumetric changes in blood flow at distance from the body using imaging devices to capture changes in transmitted or reflected light. Imaging ballistocardiography (iBCG) typically leverages optical flow estimation to track the vertical motion of the head or body from a video sequence.

Imaging photoplethysmography (iPPG) is used to remotely measure the blood volume pulse using a camera. Traditionally, it has been employed to estimate heart and respiratory rates, and recently blood pressure and oxygen saturation.

2022年1月1日 · 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.
