适形指数和均匀性指数的临床应用

Clinical applications of conformity index and homogeneity index

随着技术的进步，可以快速地获得多个放射治疗计划。每个计划中与治疗相关的参数很多，分析它们不仅复杂而且耗时，所以，放射肿瘤医师很难在多个治疗计划中做出选择。为了解决这一问题，开发整合这些参数的快速工具适形指数和均匀性指数。本文对适形指数和均匀性指数的种类发展、公式和各公式特点进行综述，期望能为使用者提供参考。

With the development of technology, several treatment plans can be got easily. There are many parameters related to the treatment in each plan and it is not only complex but also timeconsuming to analyze them. So it is difficult for radiation oncologists to choose a plan. In order to solve the problem, a fast tool was developed integrating parameters such as conformity index and homogeneity index. This paper reviewed the type development, formula and features of conformity index and homogeneity index, in order to provide reference for users.
