The skin-sparing effect of megavoltage photons is lost to a varying extent when tangential beams are used to irradiate the chest wall. The skin dose for this technique, with and without a bolus, was investigated for 4- and 6-MV photons using film, thermoluminescent dosimeters, and an ionization chamber. Metal/tissue interface effects were observed when a flexible brass fabric material was used as a bolus.
当使用切线野照射胸壁时，兆伏级光子的皮肤 sparing 效应会在不同程度上丧失。使用胶片、热释光剂量计和电离室，研究了这种技术在有和没有 bolus 的情况下，4 兆伏和 6 兆伏光子的皮肤剂量。当使用柔性黄铜织物材料作为 bolus 时，观察到了金属/组织界面效应。
