Absorption coefficient of biological tissue is an important parameter in biomedicine, but its determination remains a challenge. In this paper, we propose a method using focusing photoacoustic imaging technique and internal light irradiation of cylindrical diffusing fiber (CDF) to quantify the target optical absorption coefficient. Absorption coefficients for ink absorbers are firstly determined through...
Determination of light absorption distribution in the prostate tissue irradiated by diffusing light source is important for the treatment planning. In this paper, a three-dimensional (3D) optical model of human prostate is developed, and the light absorption distribution in the prostate tissue is estimated by Monte Carlo simulation method. Light distribution patterns including 3D distributions in...
