Abstract EN
This paper proposes a hybrid hyperthermia treatment system, utilizing two noninvasive modalities for treating brain tumors.
The proposed system depends on focusing electromagnetic (EM) and ultrasound (US) energies.
The EM hyperthermia subsystem enhances energy localization by incorporating a multichannel wideband setting and coherent-phased-array technique.
A genetic algorithm based optimization tool is developed to enhance the specific absorption rate (SAR) distribution by reducing hotspots and maximizing energy deposition at tumor regions.
The treatment performance is also enhanced by augmenting an ultrasonic subsystem to allow focused energy deposition into deep tumors.
The therapeutic faculty of ultrasonic energy is assessed by examining the control of mechanical alignment of transducer array elements.
A time reversal (TR) approach is then investigated to address challenges in energy focus in both subsystems.
Simulation results of the synergetic effect of both modalities assuming a simplified model of human head phantom demonstrate the feasibility of the proposed hybrid technique as a noninvasive tool for thermal treatment of brain tumors.
