摘要
基于正常乳腺的解剖学结构和生理学特征,建立了一个乳腺组织多维热传递模型。该模型考虑了代谢产热、血液灌注和动静脉血管与组织间热的相互作用,采用有限元分析方法求解热传导方程,数值模拟正常乳腺的稳态温度分布,着重研究血液灌注和代谢产热对正常乳腺组织温度分布的影响。研究结果可为乳腺疾病的热图像分析提供重要参考。
A multi-dimension comprehensive thermal model is presented to simulate the steady temperature distribution of breast based on the breast anatomical structure and physiological characteristics. This model takes the metabolic heat generation, blood perfusion and vascular thermal interaction into account. Finite element analysis method is used to solve the heat diffusion equation. The simulated results show that the temperature distribution of breast can be significantly affected by the metabolic heat generation and blood perfusion. Results are valuable for the thermography of breast diseases.
