摘要
通过计算机模拟雷诺准则下各种直径的大血管对肝癌微波热场凝固区外边界的影响 ,对各种临界状态 ,即 :大血管位于凝固区外 ,对 5 4℃等温面产生影响的临界距离 ;大血管处于凝固区外边界的临界距离 ;大血管完全位于凝固区内 ,其周围组织均不低于 5 4℃的临界距离的规律进行了探索 ,绘制出各种临界状态下 ,大血管直径、血管
The rule of the impact of large blood vessels on the lesion boundary of invasive microware heat field coagulation for liver tumor was studied for different critical conditions by computer simulation under Reynolods law. The critical conditions are:when the large blood vessels are located out of coagulation lesion; the critical distance when the 54℃ isothermic surface is influence; the critical distance when large blood vessels are located on the outer edge of coagulation lesion; when the large blood vessels are all located within coagulation lesion; and the critical distance when the temperature of their surrouding tissue is not less than 54℃, Curves were rendered for relationship between diameters of large diameter blood vessels and distances-blood vessels under different critical conditions.
