Abstract

This paper reports studies on EM characterization, instrumentation development and proof of concept experimental evaluation of a novel system capable of focused microwave therapy (FMT) at 915 MHz integrated with thermoacoustic imaging (TAI). The combined TAI-FMT prototype assists accurate dielectric property mapping, precise temperature prediction and treatment monitoring through TA thermometry feedback for adaptive beamforming. A 32-element array prototype is simulated and focusing is evaluated through time reversal. Initial experimental results using a 4-element FMT system showed 2°C accuracy in temperature prediction.
