摘　　要：介绍治疗计划评估的几种方法,重点探讨参照剂量分布取舍治疗计划的尺度。结果表明,精心设计的治疗计划能使肿瘤区域接受到高的治疗剂量,而周围正常组织和器官接受的剂量最少。In this paper, we briefly introduce 3 methods of evaluation for a treatment plan, and mainly discuss the criteria of the plan's optimization based on dose distribution. The elaboratively-designed treatment plan is capable of having the tumor receive higher dose level while the normal tissues and organs receive minimum dose level.
