| Abstract |
In the medical world, heat transfer studies can be used as tumor therapy. At a temperature of ≥40oC, a tissue will stop growing and die. One therapy that uses this concept of heat transfer is intersti...tial hyperthermia therapy. The high temperature given will certainly have an impact on the normal tissue around the tumor. Thus, the use of interstitial hyperthermia therapy requires the ability to adjust the right heat source, both based on space, time, and other supporting factors, such as metabolic heat, so that optimal success will be obtained. This study analyzes the influence of metabolic heat on the distribution of temperature in the human hands in interstitial hyperthermia therapy under unsteady conditions. The Pennes bioheat equation and the finite element numerical method are used to determine the value of the temperature distribution. This study was conducted for 600 seconds and variations in metabolic heat values were used in the form of 0 W/m3; 368.1 W/m3; 500 W/m3; 800 W/m3 and 1200 W/m3. In this study, metabolic heat influences temperature distribution that occurs in the interstitial treatment of hyperthermia therapy. This is because metabolic heat will provide heat from the inside so that the temperature in the tissue will increase.show more
