Abstract

Time gating for laser imaging and tomography of biological tissues is a rapidly developing and promising approach to biomedical diagnostics based on laser probing. There are good reasons to hope that in future the tomography utilizing IR radiation will become competitive with traditional x-ray tomography due to its safety and potentially high resolution. There is also growing interest in retrieving information about functional characteristics of tissues rather than just stationary imaging. In the present paper we consider the results of Monte-Carlo simulations and discuss the opportunities of time-gated laser Doppler flowmetry as a technique providing information about moving components of biotissues. Our main concern is with possible improvements in spectral and spatial resolution characteristics of the laser Doppler flowmeters operating in back-scattered and transmitted light modes.
