Radiation therapy of tumors is often performed with high energy electrons. In certain situations air cavities in the irradiation volume can change the dose distribution. The effects of air cavities on the dose distribution are investigated. The results calculated with a therapy planning system and measured in a phantom are described and compared with one another and with the literature.
肿瘤的放射治疗通常采用高能电子束进行。在某些情况下，照射体积内的气腔会改变剂量分布。本文研究了气腔对剂量分布的影响。描述了使用治疗计划系统计算并在体模中测量的结果，并将它们相互之间以及与文献进行了比较。
