本文采用真实的三维头部组织结构,基于发展的高效数值算法,研究了脑肿瘤冷冻消融过程中生物组织相变传热机理,并讨论了冷冻探针尺寸、数量及其制冷能力等参数对冷冻消融区域的影响。同时,我们还考察了血液灌注率的热效应。本文研究方法和结果为制定脑肿瘤冷冻消融方案具有重要的临床指导意义。 In this paper, the real three-dimensional head tissue structure is used to study the heat transfer mechanism of biological tissue transformation during brain tumor cryoablation based on the development of efficient numerical algorithm. The effects of freezing probe size, quantity, Effect of ablation zone. At the same time, we also examined the thermal effects of hemoperfusion rates. The research methods and results of this article have important clinical significance for the development of brain tumor cryoablation programs.
