Numerical Modeling and Optimization of Acoustic Fields and Designs for High-Intensity Focused Ultrasound Transducers

Abstract

Recent advances in the fields of physical acoustics, imaging and imaging techniques, piezoelectric materials, and ultrasound transducer designs have led to the emergence of new methods and equipment for ultrasound diagnostics, therapy, and aesthetic medicine, and to the development of traditional and emerging new applications. Ultrasound transducers for medical diagnostic equipment, particularly high-intensity focused ultrasound transducers (HIFU), are one promising use of piezoceramic and composite materials. This work is devoted to the development of mathematical models, numerical modeling, and optimizing acoustic fields and transducers of this type made of porous ferroelectric piezoceramics.
