STUDY OF INSTANTANEOUS BIOHEAT TRANSFER IN HUMAN TISSUE DURING CRYOGENIC SURGICAL OPERATION

Abstract

An approximate analytical solution presented by Cooper for predicting the radius of the frozen phase, S, of human tissue during cryosurgical operations has been widely used. Based on consideration of the Stefan number, Ste, another approximate analytical solution for S has been developed in this paper. The new technique has the advantages of simple form, reasonable structure, good accuracy, and quantitative agreement with experimental data.
