Abstract

Soft heating, where thermosensitive magnetic materials inserted into the tumor as a heater produce heat in a high-frequency magnetic field, has been proposed as one method. Although the heater needs to be implanted in the tumor tissue, soft heating has advantages including easy retreatment, localized tumor heating, and a low degree of invasiveness. We created thermosensitive magnetic powder coated with Ag paste as a heater. As a result, this powder produced a greater amount of heat due to losses through hysteresis and inductive current than the magnetic powder alone, and we could also control the temperature of the heater by using the Curie point.
