The phantom plays an important role in hyperthermia as well as in radiation therapy. Uses of the phantom in hyperthermia are as follows : 1) development of heating equipment and thermometers ; 2) experimental verification of absorbed power or temperature distribution obtained by calculation ; 3) prediction of the absorbed power or temperature distribution in the body ; 4) bolus for compensating the absorbed power distribution in the body ; 5) filler for obtaining an impedance which matches that between the applicator and the body ; 6) medium for cooling the surface of the body. In order to discuss the phantom, it is necessary to understand the physical, thermal, ultrasonic, and electrical characteristics of the living body. Therefore we will explain the above characteristics first and then describe the phantoms used for ultrasound and electromagnetic waves in detail.
