A study of opto-physiological modeling to quantify tissue absorbance in imaging photoplethysmography
conference contribution
posted on 2016-08-03, 11:36 authored by Sijung HuSijung Hu, Jia Zheng, Vicente Azorin-PerisThis paper presents an opto-physiological model
(OPM) to quantify the absorbance of multi-layered tissue in
imaging photoplethysmography (IPPG). The approach used to
generate such a model is to revise the path length of the Beer
Lambert law through the Monte Carlo (MC) simulation of
multi-layered tissue. The OPM can mathematically quantify
the effect of optical properties on the absorbance of multilayered
tissue. Subsequently, the absorbance measured from
homogeneous, multi-layered tissue phantoms compares with
model predictions. To this end, the model is validated to predict
the widest range of experimental outcomes while maintaining
the highest possible level of accuracy. This study brings a new
approach to understand the principle of IPPG.
