Monte Carlo simulation of transit time dependence of Doppler spectra in dynamic time-resolved tomography

摘要

Abstract: Time-resolved laser tomography is a promising techniquefor noninvasive laser examination of structure andcondition of biotissues. The results of Monte-Carlosimulations discussed in this paper are related withtime-resolved laser Doppler tomography of bloodtransport in the tissues. In this technique thetemporal variations of the optical signal carryinformation about blood transport. By simulating laserlight propagation in a human skin model an opportunityfor in-depth by selecting the photons with short,medium, and long transit times. As an example apossibility for detection of a small blood vesselembedded in dermis is considered. !4
