The basic study of intracavitary and interstitial hyperthermia was made with the Soft-Heating Method. In this method, a hybrid device composed of non-magnetic metal ring and ferrite rod is used as a heater. Being exposed to external magnetic field, the device produces heat, and its temperature rises to the Curie Temperature of the ferrite rod with self-regulation. The accuracy of the regulation is +/- 0.2 degrees C near the Curie Temperature which can be set up almost freely. In addition to that, the frequency of magnetic field is not so high (20-50 KHz) that there is no damping nor reflection of the field in a human body. Therefore the system seems to be very useful for hyperthermia of deep seated tumor. In this paper, experimental discussion of the possibility of local hyperthermia by the system is made. From the results, it is concluded that the system will be applied to clinical uses.
采用软加热法对腔内和组织间热疗进行了基础研究。在该方法中，一种由非磁性金属环和铁氧体棒组成的混合装置被用作加热器。该装置暴露于外部磁场时会产生热量，其温度会自我调节升高至铁氧体棒的居里温度。在居里温度附近调节精度为±0.2℃，且居里温度几乎可以自由设定。此外，磁场频率不高（20 - 50千赫兹），在人体中不会产生场的阻尼或反射。因此，该系统似乎对深部肿瘤的热疗非常有用。本文对该系统进行局部热疗的可能性进行了实验探讨。从结果得出，该系统将应用于临床。
