Abstract

The feasibility of using multi-layered transducers for variable frequency interstitial ultrasound thermal therapy was investigated. KLM calculations and experimental measurements evaluated the ability to transmit high intensity ultrasound at multiple frequencies from a single transducer. Heating simulations demonstrated the improved control over lesion depth with this design. Using a quarter wavelength PZT front "mis-matching" layer, two transmission bands at 3.5 and 7.5 MHz were possible, resulting in the ability to control the lesion depth by a factor of 1.5 in tissue.
