Experimental evaluation of UWB applicator prototype for head and neck hyperthermia

The laboratory prototype of an UWB hyperthermia applicator is presented and tested for treatment of tumors in head and neck region. The focusing ability of the presented applicator for treatment of neck tumors has been tested on a homogeneous muscle phantom at 500 MHz. Two tumor positions were investigated: one in the center and one in the side of the mid-transverse plane of the phantom. The captured temperature images show the agreement between the planned and the measured focal spots and acceptable temperature increase in these areas.
