Imaging photoplethysmography (IPPG) is one of the emerging medical imaging modalities to visualise peripheral blood perfusion of a specific tissue. Blood perfusion. defined as the blood volume exchange. can provide numerous information of physiological function for tissue and for cardiac-vascular system. For current IPPG, most published observations are based upon a qualitative nature of blood perfusion. The performance of IPPG is difficult to investigate in these measurements as it is difficult to determine experimentally the effect of changes in the optical properties of segmented biological tissues on the output signals. Thus a representative model for the quantification of this effect is necessary to better understand the underlying principle of the IPPG signal and further improve the applicability of IPPG. This research aims to develop such an appropriate opto-physiological model to quantify IPPG signals with segmented optical properties of tissue. [Continues.]
