Optical parameters of embedded abnormalities in tissues as determined by Monte Carlo simulation

Abstract

The backscattered fraction of laser incident beam from the biological tissues depends on their composition, leading to change in their optical properties. The tissue models consist of heart tissue as the base embedded with adipose and spleen tissues at various depths from the tissues surface Monte Carlo simulation is carried out to detect the changes in back-scattered fraction (BSF) at various locations on the tissue surface. The BSF is increased and decreased with the presence of adipose and spleen tissues located at various depths, respectively. The location of these is carried by construction of the BSF images by scanning at various locations. From the variation in images the location and type of abnormality is determined. Thus this study provides the possibility of detection of various changes in tissue composition
