Breast Cancer Hyperthermia Treatment Based on Slotted Patch Antenna at 2.45 GHz ()
ABSTRACT
The present work proposed a simple model for breast cancer hyperthermia
treatment at 2.45 GHz. The proposed model involves nine-element
antennas alongside a numerical breast comprising multiple tumors. Using a
coupled EM-Thermal simulation in the CST suite, the simulated results for a
single antenna showed a reflection coefficient (S11) better than -47 dB and demonstrated a bandwidth of 78 MHz.
The specific absorption rate (SAR) as a function of input powers was examined
inside the breast tissues, where it exhibited a promising performance higher
than 3 W/kg at the tumor volume when the applied power was
at a reasonable level of 1.5 W whereas it was well attained under the recommend
IEEE level of 1.6 W/kg through the surrounded health tissues. Taking
into consideration nine-element antennas covering the breast containing two
different located tumors, the maximum temperature as a function of treatment
time was presented at which a resulting temperature of 43°C was obtainable
within 10 minutes, favored for hyperthermia purposes. Considering the maximum
power level of 1.5 W, the potential use of applying three-element
antennas, simultaneously with 0.5 W, could be achieved.
