Evaluation of a Patch Antenna Applicator for Time Reversal Hyperthermia

Popis výsledku v původním jazyce

Analysis and evaluation of a new antenna array system for microwave hyperthermia is being described in this paper.This antenna array was evaluated by the focusing method based on the time-reversal principle.Power absorption distributions in a cylindricalhomogeneous and inhomogeneous phantom were calculated for the frequency range 500-900 MHz. Two set-ups with 12 and 16 antennas were analysed by comparing changes in focusing areas enclosed by the 50%, 75% and 90% iso-SAR contours. The sharpest focusingarea in the centre of the phantom, 151mm2 (920mm) (90% iso-SAR), was obtained by using 16 antennas at frequency 900 MHz. The largest focusing area of 280mm2 (1324mm) (90% iso-SAR) was obtained by using 16 antennas at 500 MHz. The conducted study confirmsthe feasibility of the time-reversal-based focusing methods for microwave hyperthermia. The proposed system shows promise and is suitable for further development in the treatment of head and neck tumours, and extremities applicatio
