The use of magnetic nanoparticles to increase the efficiency of magneto-ultrasonic heating.

Hyperthermia treatment is a medical procedure that involves generation of heat between 41˚C and 45˚C. This temperature rise leads to several physiological changes within the tumor tissues causing their weakening. Weaken cells are more susceptible for other cancer therapies. Hyperthermia within the tissue can be applied through different mechanisms. It can be induced by ultrasound sonication, radiowaves or magnetic field. In this work magnetic, ultrasound and novel magneto-ultrasonic source of hyperthermia are discussed. To investigate the magneto-ultrasonic thermal effect tissue mimicking phantom, doped with magnetic nanoparticles, is simultaneously irradiated with the focused ultrasonic wave and the alternating magnetic field. During this magneto-ultrasonic heating even more effective thermal effect can be observed. This novel simultaneous magneto-ultrasonic heating has a big application potential in treating cancer at a lower magnetic particle concentration and in shorter exposure time. The coupling of magnetic and ultrasound hyperthermia gives possibility for developing the new, innovative thermal therapy.
