Abstract:
Based on the anatomic data and fractal theory, the vascular tree model of forearms similar to actual vessel was established, and then the 3D heat transfer model of forearms based on the actual vessel anatomic structure was created. The model was analyzed and investigated with finite element method to explore the influential factors such as dimensional distribution of vessel, blood perfusion rate and external heat source for the 3D temperature field. The simulation results were consistent with the experimental data derived from Pennes. The model well reflects the regional difference of tissue temperature caused by the irregular distribution of vessel, and provides temperature guidance for tumor thermotherapy.
