Study on the Method to Create the 3D Arterial Trees of Human Tongue

摘要

Simulation of the 3D temperature field of the organism as the arterial tree is taken as a heat source is an accurate way to calculate the bio-heat transfer. Based on the corrosion casts of real arterial tree of human tongue, a vessel model tree is grown by a stepwise method. Firstly, the profunda lingual artery and the branches of first level were constructed by statistical rule. And then else arteries were modeled based on physical laws and optimization criterion. The arterial tree of human tongue formed by the stepwise method is compared with the corrosion cast of real arterial tree. Result shows that this arterial model tree is in good agreement with the actual structure of arterial tree of human tongue. This method can substitute the vessel cast experiment, and can create arterial trees with different configuration which is the basis to research the process of heat transfer of organism deeply.
