Paper Abstract

The development of therapeutic ultrasound requires specially adapted transducers for the generation of high intensity focused beams. New piezocomposite technologies have been developed to take into account the high power requirements and constraints like the high degree of focussing, the capability to withstand thermal shocks, the requirement for safe and reliable transducers, the compatibility with MRI and Ultrasonic imaging systems. This approach enables a wide variety of shapes and the design of array transducers for electronic focusing, scanning and steering of the therapeutic beam. Recent results will be presented on power and efficiency aspects. The feasibility of highly focused transducers with several array structures as well as the combination of these technologies with MRI and Ultrasonic imaging systems will be illustrated through various examples.
