Finite element model of heat flow in biological tissue undergoing laser irradiation.

In this paper we present a numerical method to determine thermal effects in biological tissue undergoing laser irradiation. The scattering and absorption of the laser beam have been analysed. Results are compared with experimental observations.

The finite element method--a new approach to determination of heat flow in the eye shown in an example of cryotherapy--preliminary report.

The finite element algorithm is presented for the determination of heat flow within the partially frozen cornea during cryotherapy. The latent heat involved in phase change was taken into account by virtue of the enthalpy defined as the integral of heat capacity with respect to temperature. The numerical method is used to analyze the freezing process within the cornea in cryotherapy.
