Development of Accistance System for High Accuracy Breast Cancer Radio Frequency Ablation

近年来，射频消融（RFA）治疗作为乳腺癌的微创治疗备受关注。为提高射频消融治疗效果，研制了高精度乳腺癌射频消融治疗支持系统。该系统主要由高精度温度分布模拟器和穿刺工艺优化两部分组成。作为一些体内实验的结果，温度分布模拟器使得实验结果和分析结果之间的温度差在4.0 ℃以内的重复性高。并且，在获得乳腺癌最佳穿刺的过程中，我们开发了最佳穿刺条件。该条件是利用猪乳房内植入的模拟肿瘤进行体外实验而得。

Recently the radio frequency ablation (RFA) treatment is focused on as minimally invasive treatment for breast cancer. In order to improve treatment effect of RFA, we developed the support system of RFA treatment for breast cancer ablation high accurately. Our system mainly consists of high accuracy temperature distribution simulator and optimal process for puncture. As the results of some in vivo experiments, the temperature distribution simulator enable to be high repeatability that the temperature difference between experimental results and analysis results is within 4.0 deg C. And, in obtaining the process of optimal puncture for breast cancer, we developed the optimal puncture condition. This condition was derived from in vitro experiments by using simulant cancer which was implanted in hog breast.
