Abstract
Ultrasound-mediated tumor perfusion enhancement offers a promising strategy to overcome treatment resistance. To enable precise therapy, we developed a dual anti-matching layer transducer array capable of simultaneous imaging and power output. Simulation results show a 31% increase in pulse-echo sensitivity and a reduction in -6 dB bandwidth from 61.9% to 55.5%. The fabricated transducer array achieves a -6 dB bandwidth of 56.5%, close to the simulation, with uniform acoustic output suitable for therapeutic use.
