在血管树模拟研究的基础上,运用混合生物热传导模型并采用考虑血管和组织间局部传热的血液灌注率,改进了传统的 Pennes 生物传热方程。运用 COMSOL Multiphysics 对其进行仿真,并对改进前后 Pennes 方程求解结果进行比较,结果表明,改进后的 Pennes 方程能够显示出血管树对组织区域温度分布的局部影响,而传统 Pennes 方程则只表述了组织中温度分布的均匀形式。
在血管樹模擬研究的基礎上,運用混閤生物熱傳導模型併採用攷慮血管和組織間跼部傳熱的血液灌註率,改進瞭傳統的 Pennes 生物傳熱方程。運用 COMSOL Multiphysics 對其進行倣真,併對改進前後 Pennes 方程求解結果進行比較,結果錶明,改進後的 Pennes 方程能夠顯示齣血管樹對組織區域溫度分佈的跼部影響,而傳統 Pennes 方程則隻錶述瞭組織中溫度分佈的均勻形式。

Based on the studies of the vascular tree’s simulation and combined with the mixed bio-heat transfer model,the traditional Pennes bio-heat transfer equation was improved by using the blood perfusion considering the local heat transfer between the blood and the tissue. COMSOL Multiphysics was used to simulate,and the results of Pennes equation improved before and after were compared. The results showed that the improved Pennes equation could reflect the local influence of the vascular tree on organization’s regional temperature distribution,while the traditional Pennes equation only described the homogeneous form of tissue temperature distribution.
