Abstract

A clinical study of the evolution of the space resolved reflectance with the subcutaneous layers thickness, at rest, on the vastus lateralis, is used to determine convenient sets of muscle and fat optical coefficients at 850 nm. The results are compared to the data available in the literature. When the same study will be completed at 780 nm, these coefficients will be used in 3 layers MC simulations to establish pre-calculated tables of the reflectance as a function of the fat thickness and of the muscle absorption coefficient. The goal of this study is eventually to perform real time inversion during effort in order to determine the muscle oxygenation with this very simple technique (part 2).
