Compared to the conventional finger PPG sensor that is widely used in clinical practice to assess arterial blood oxygen saturation and heart rate, an imaging PPG (IPPG) system can remotely provide multiple contactless measurements across large areas of the body to give valuable vascular and cardiovascular information. The IPPG technique is non-contact and can be a low cost and easy to perform tool for use in medical diagnostics as well as in biological-medical research of the cardiovascular system. The technology and optical modelling with the technique continue to be develop but already IPPG can provide potentially useful information for investigating a number of clinical and physiological conditions. In this chapter, we will overview a range of different IPPG applications, particularly beyond the standard PPG assessments of pulse oximetry and the monitoring of heart and respiratory rates. These applications include the intra-operative monitoring of cerebral microcirculation, the visualization of skin capillary function across the body, assessing the circulatory-system reactivity in response to functional testing, evaluating the functional reserve of cerebral and musculocutaneous vessels, instrumental identification of scleroderma, and the contactless assessment of endothelial function.
