Finite Element Modeling of an Ultrasonic Transducer

Ultrasonic transducers are integrated into the minimally invasive needles and catheters for medical diagnostic. There is a need for a model that can predict the behavior of the ultrasonic transducer. Many designers employ one dimensional analytic models, however due to certain limitations these models are not adequate to understand the entire performance of an ultrasonic transducer. Nowadays, finite element modeling is being adopted in the design of ultrasonic transducers. The purpose is to get more realistic transducer simulations and to accelerate the design process. In this report, a literature survey is presented in order to model the complete ultrasonic measurement system using the finite element method.
