近年来，肿瘤放射治疗在理论和技术上均有重大进展，从而使肿瘤的放疗疗效不断提高，同时也对临床放射剂量学提出了更高的要求。为确保放射治疗计划准确地执行，必须在放射治疗时进行剂量实时测定（ｉｎｖｉｖｏｄｏｓｉｍｅｔｒｙ）［１，２］。１剂量实时测定的必要性多... In recent years, tumor radiotherapy has made great progress both in theory and in technology, so that the efficacy of radiotherapy for cancer has been continuously improved, and higher requirements for clinical radiation dosimetry have also been put forward. In order to ensure the accurate implementation of the radiotherapy plan, real-time dose determination (invivodosimetry) must be performed during radiotherapy [1,2]. 1 dose real-time determination of the need for more ...
