| Abstract: | The prospects for developing a new noninvasive medical diagnostic technique, such as optical (laser) tomography of biological tissues largely depend on the feasibility of designing an adequate mathematical model for the reconstruction of images of the spatial structure of objects that are in the highly scattering medium (HSM). The basic difficulty is that it is necessary to effectively describe the physical properties and the propagation pattern of photons of different types in such a medium. This review considers methods for describing the distribution of laser ultrashort pulses in HSM with particular emphasis on a new nonstationary two-flux model of radiation transfer. |
