摘要

用蒙特卡罗法计算了用10-366keV的光子源敷贴治疗时一种简化血管瘤模型中的剂量分布。计算结果表明

临床治疗时

光子能量应选在30keV附近

这样既有很好的治疗效果

又可适当减少对正常组织的照射。用

125

I对30余例混合型、海绵状血管瘤进行的治疗疗效显著

随访中没有发现皮肤溃烂等现象。同时给出了10Gy的瘤体平均剂量对应的各种能量下的光子数。

Abstract

The dose distribution in an angioma treated with a surface photon source was calculated by using Monte Carlo method . The photon energies ranged from 10 to 366keV

The results showed that photon energy should be near 30 keV in actual treatment. This photon energy can result in a good curative effect and is relatively safe for normal tissue under the angioma. Thirty odd cases of angioma with several centimeters was treated with125I and most of them had very good curative effects. No skin ulceration was found.
