Paper Abstract

Laser prostatectomy is an alternative to conventional surgical resection. However, clinical studies lack sufficient power to determine optimal exposure parameters. This paper describes axi-symmetric and 3D finite element models of heat transport in laser irradiated tissue. These models have been verified with an analytical solution for a laser with a Gaussian beam profile using both stationary, and scanning laser beams. Percent errors between the analytical solutions and the finite elements solutions were less than 7%. Further development of these models will facilitate optimization of laser prostatectomy methods.
