The response of an implantable in vivo dosimetric system based on gallium nitride radioluminescence was investigated for electron beam radiotherapy using ELEKTA SLi and VARIAN Clinac 2100 CD Linear Accelerators. A bi-channel method has been implemented for fibre background rejection. The percentage depth dose (PDD) profiles were measured in polymethyl methacrylate for 6, 12 and 18 MeV electron beams. The PDD results were in excellent agreement with those measured with reference to ionisation chambers.
使用ELEKTA SLi和瓦里安Clinac 2100 CD直线加速器，对基于氮化镓辐射发光的植入式体内剂量测定系统在电子束放射治疗中的响应进行了研究。已采用双通道方法来抑制光纤背景。在聚甲基丙烯酸甲酯中测量了6、12和18 MeV电子束的百分深度剂量（PDD）分布。PDD结果与参照电离室测量的结果高度一致。
