The authors set out the technical innovations which are being used to comply with the three classical aims of endocavitary curietherapy for cervical cancer: the personalization of the irradiation device, protection of staff against exposure risks due to ionizing radiations, planning and control of the irradiation conditions. The personalization of the irradiation device is achieved by preparing a specially shaped vaginal applicator for each patient, and staff protection is ensured by the use of remote-loading techniques and closed circuit television control for in-patients. The planning of the treatments answers to the logic of reproducing the usual curie therapy method with conventional radium-226 sources. In order to control the irradiation conditions, at least the essential part of the treatments must be recognized and expressed: equivalent radium milligrams per hour (MRA h), dose rate (Gy h-1), dimensions of the treated volume and space distribution of the dose.
照射装置的个性化、保护工作人员免受电离辐射的暴露风险、照射条件的规划与控制。照射装置的个性化是通过为每位患者制备特殊形状的阴道施源器来实现的,而工作人员的保护则通过使用远程加载技术和对住院患者的闭路电视控制来确保。治疗规划符合使用传统镭 - 226源重现常规居里治疗方法的逻辑。为了控制照射条件,至少必须识别并表述治疗的基本部分:每小时等效镭毫克数(MRA h)、剂量率(Gy h-1)、治疗体积的尺寸以及剂量的空间分布。
