In order to study scattering properties of normal and cancerous tissues from human stomach, we collect images for
human gastric specimens by using phase-contrast microscope. The images were processed by the way of mathematics
morphology. The equivalent particle size distribution of tissues can be obtained. Combining with Mie scattering theory,
the scattering properties of tissues can be calculated. Assume scattering of light in biological tissue can be seen as
separate scattering events by different particles, total scattering properties can be equivalent to as scattering sum of
particles with different diameters. The results suggest that scattering coefficient of the cancerous tissue is significantly
higher than that of normal tissue. The scattering phase function is different especially in the backscattering area. Those
are significant clinical benefits to diagnosis cancerous tissue© (2012) COPYRIGHT Society of Photo-Optical Instrumentation Engineers (SPIE). Downloading of the abstract is permitted for personal use only.
