对放疗计划的评价,过去虽有一般性原则,但不够精确,具体。本文综合了一些文献报告,并根据临床实践提出以下评价标准。 一、评价项目: 1、靶区剂量: ①最大剂量点的位置。 ②靶区剂量均匀性。 ③靶区体积占高剂量区体积的百分比。 2、体积积分剂量比。 3、靶区外剂量分布与正常组织耐受剂量的关系。 Although there were general principles in the past for evaluation of radiotherapy plans, they were not precise enough and specific. This article synthesizes some literature reports and proposes the following evaluation criteria based on clinical practice. First, the evaluation project: 1, the target area dose: 1 the location of the maximum dose point. 2 Target area dose uniformity. 3 The volume of the target volume as a percentage of the volume of the high dose zone. 2, volume integral dose ratio. 3. The relationship between dose distribution outside the target area and normal tissue tolerated dose.
