A Study of the Thermophysical Properties of Human Prostate Tumor Tissues in the Temperature Range from–160 to +40°C

详细

A differential scanning calorimetry study of the specific isobaric heat capacity, phase-transition enthalpy, moisture content, and cryoscopic temperature for samples of benign and malignant human prostate tumor tissues is reported. Empirical relationships have been obtained that describe the specific isobaric heat capacity of prostate-tissue samples in a wide temperature range and the effect of the moisture contents of the samples on the cryoscopic temperature and the heat of the phase transition, as well as a semi-empirical relationship that describes the effective specific-heat capacity in the subcryoscopic temperature range. The correlations and experimental data presented in this article can be used in mathematical modeling and optimization of heat-exchange processes in cryosurgery.
