Abstract

Hyperthermia is one of cancer thermotherapies and there are several ways of heating. Among them, we have researched the Soft-heating method. In this method, we insert heating elements, which consists of processed thermosensitive magnetic materials, and apply a high frequency magnetic field to them by an excitation coil placed outside the body. With this method, the temperature of the heating elements rises up to the Curie point and therefore, we can cure tumors without overheating them. It has been revealed that magnetic flux density of 3 mT is required at 100 kHz in order to excite the elements sufficiently. Then we have applied the LC booster method, which makes it possible to generate a high current by utilizing the magnetic coupling between two coils. In this method, we connect a primary coil with a power source, and use the excitation coil as a secondary coil. This makes the load on a power source lower and enables the excitation coil to move freely. This study presents the design of a primary coil that can induce a needed current efficiently in excitation coil and examines the effect of the change in the relative distance between the two coils on the excitation current.
