摘要
介绍了用于宫颈癌腔内热疗的微波辐射器的设计方法和测试结果。这种辐射器与常规微波辐射器不同的是 ,其前部的内导体被一个带有反射罩的锥形螺旋天线所替代。在模拟肌肉组织中 ,我们证实这种辐射器的热场分布向前端偏移 。
A new microwave applicator for intracavitary hyperthermia treatment of uterocervical cancer has been designed and tested. Compared with the traditional microwave applicators, the exposed inner conductor of this applicator is replaced by a cone helical antenna with the reflect shade. We confirm that the heat pattern of the applicator is shifted towards the tip in muscle tissue equivalent phantom material. The result indicates that this new applicator may play an important role in clinical use for treatment.
