Operation of the magnetic micro-machine with the hyperthermia mechanism and its exothermic characteristic

Summary form only given. Among the treatments for cancer tissue, hyperthermia is known as a minimally invasive treatment technique. With this therapy, we propose a ´soft heating´ method, which allows thermosensitive magnetic materials embedded in the body to be heated by the application of the external magnetic field, thus necrotizing the tumor tissues. Our method, a non-contact heating system without the necessity of temperature measurements, uses as a heating element thermosensitive magnetic materials with Curie temperature, sufficient enough not to cause a damage to the rest besides the tumor site. In the paper we have examined a cancer treatment which enables an effective heating of the objective affected area, in combination with a significantly improved hybrid heater for the heating efficiency and a movable magnetic micro-machine in gels utilizing the external magnetic field.
