基于EPID的在体剂量验证研究进展

Research progress in electronic portal imaging device-based in vivo dosimetry verification

在体剂量学方法是目前最直接、最有效的质量保证手段之一.EPID因具有优良的剂量学特性而被用于在体剂量验证.近年来,国内外有很多关于EPID的在体剂量学方法研究.此文目的是对基于EPID的在体剂量学方法研究进行综述,了解其研究现状,为后续运用研究和扩展提供参考.

In vivo dosimetry （IVD） is currently the most direct and effective means of quality assurance.The electronic portal imaging device （EPID） has been widely used for IVD verification owing to its favorable dosimetric properties.In recent years,an increasing number of EPID-based IVD studies have emerged around the world.The purpose of this paper is to give an overview of the present progress in EPID-based IVD studies,and to provide a reference for the subsequent application of EPID in IVD.
