摘　　要：用血管树作为内热源进行生物体三维温度场重构是一种较为精确的生物传热计算方法.以人舌血管铸型为模板,采用数学方法分步建立其血管树.根据统计规律建立形态走向复杂的舌深动脉和一级分支血管,然后依据生理组织结构规律和优化原则生成其它血管.与实际人舌血管铸型进行对比,结果表明:该方法建立的血管树符合人舌血管树的生理结构.用此方法可以替代生物体血管铸型实验,生成具有不同形态特征的血管系统,为深入研究生物体内部的传热特性提供了基础.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.
