近年来,微波热疗技术迅速崛起,并得到推广普及。这是因为微波热疗具有广泛的适应性,尤其是用于治疗癌症,可对肿瘤细胞产生选择性加热,起到杀伤作用,而不伤害正常的细胞。医用微波辐射器是微波治疗设备中的关键部件,其设计与制造难度均较高。目前,国外投入了大量人力物力,对这类部件进行了研究,取得了一定成果,各种 In recent years, microwave hyperthermia technology has rapidly risen and has been popularized. This is because microwave hyperthermia has a wide range of adaptability, especially for the treatment of cancer, can produce selective heating of tumor cells, play a killing effect, without harming normal cells. Medical microwave radiators are the key components in microwave treatment equipment, and their design and manufacture are both more difficult. At present, a lot of manpower and material resources have been invested abroad, and research has been carried out on such components with certain achievements. Various
