摘要

在乳腺癌的体积调制弧线治疗中，靶的外缘是必需的。本研究评估临床和计划目标体积覆盖和表面剂量使用自动皮肤闪法与虚拟丸法比较。模拟20例乳腺癌患者4、8、12 mm的体廓变化。采用自动皮肤闪光法，V95和V90临床靶体积覆盖率和表面剂量的中位数保持在90.1%、98.7%和85.7%以上。自动闪皮法的中位数结果与虚拟丸法接近。

Performance evaluation of a new automated skin flash method for radiotherapy of breast cancer

In volumetric modulated arc therapy of breast cancer, an outer margin for the target is needed. This study evaluated the clinical and planning target volume coverage and surface dose using an automated skin flash method compared to the virtual bolus method. Body outline changes of 4, 8 and 12 mm were simulated in 20 breast cancer patients. Median V₉₅ and V₉₀ clinical target volume coverage and surface dose remained at 90.1 %, 98.7 % and 85.7 % or above with the automated skin flash method. The median results of automated skin flash method were close to virtual bolus method.
