Abstract
thermal energy distribution in biological tissue,on the treatment site can serve as an indicator for the effectiveness of a photo-thermal therapy. In this paper, thermal effects of laser irradiance on biological tissue is investigated using bio-heat transfer equation which solved using numerical solution in implicit matlab to give us 2D and 3D simulation for thermal transfer distribution during laser irradiation of biological tissue. To study the thermal energy distribution of laser on tissue, A cylindrical sample of biological tissue its radius 3mm and length 3mm was irradiated by laser beam with 808nm wavelength, from above of the cylindrical axially. The results can be used to control the laser treatment parameters and to optimize the treatment outcome.
