[Theoretical simulation of temperature distribution in electromagnetic hyperthermia of tumors].
Combined methods of tumor therapy including electromagnetic hyperthermia are used nowadays in many countries of the world. Ordinary control of temperature at several points of a heated volume by invasive temperature sensitive elements gives approximate evaluation of a temperature profile during a session of hyperthermia. The authors have proposed methods for the calculation of temperature distributions in tissues taking account of the correlation of the blood flow and temperature and its contribution to heat transfer processes in body tissues. It is assumed that the vessels are equally distributed in the body volume sparing a necessity to record each one individually. The rated temperature profiles by the depth of a heated body zone corresponding to different variants of a UHF radiator and a tumor are given. Some conclusions as to the peculiarities of electromagnetic heating of body tissues have been drawn.
