高剂量率~(60)钴后装腔内治疗方法,是子宫颈癌放射治疗工作中为了克服传统镭疗对工作人员的辐射危害,而逐步发展起来的一项新技术,亦是近年来放疗技术的重要进展之一。后装(Afterloading)技术的设想早在本世纪初即有人提出,但直到50年代核反应堆能生产适宜的放射源之后才成为实际可能。西方国家从60年代初 The high dose rate ~ (60) cobalt posterior intracavitary treatment is a new technology gradually developed in the radiation therapy of cervical cancer in order to overcome the radiation hazard of the traditional radiotherapy to the staff. It is also a radiotherapy One of the important advances in technology. The idea of ​​the afterloading technology was proposed as early as the beginning of this century, but it was not until the 1950s that nuclear reactors were able to produce the right radioactive sources. Western countries from the early 60s
