| Research Abstract |
The basic study of intracairtary and interstitial hyperthermia with the Soft Heating Method was made. In the method, a hybrid device composed of temperature-sensitive ferrite rod and non-magnetic metal ring is used as a heater. Being exposeded to external magnetic field, the device generates heat, and its temperature rises to the Curie temperature of the ferrite rod with self-regulation. The accuracy of the regulation is 0,2 C rear the Curie temperature which can be set up almost freely. In addition to that, the frequeney of the magnetic field is not so high(20-50KHz) that there is no damping nor reflexion of the field in a human body. Jherefore the system seems to be very useful for hyperthermia of deep seated tumor. In this research, experimental and clinical study of local hyperthermia by the system was made. From the result, it is concluded that the method will be applied to clinicaes.
