Ultrasonic transducers are integrated into the minimally invasive needles andcatheters for
medical diagnostic. There is a need for a model that can predict thebehavior of the ultrasonic …

Ultrasonic transducers are the most important part of an ultrasonic testing system which
significantly affect the precision and accuracy of the measurements. Piezoelectric …

Transducers as a heart of ultrasonic heads are one of the most important parts of systems.
Among them, sandwiching, adhesive and screw transducers are more applicable, so the …

Finite element modeling is being adopted in the design of ultrasonic transducers and
imaging arrays. Impetus is accelerated product design cycles and the need to push the …

This paper presents the modeling of the acoustic field of a physiotherapy ultrasonic
transducer by using the finite element method. An ideal emission is presented obtained by …

Computer simulation has been used widely in medical ultrasonic transducer designs. One
could now construct and test an transducer entirely ion a virtual basis. Such a virtual design …

This paper presents a new waveguide-based longitudinal-torsional (L&T) ultrasonic
transducer. For synchronization of both the longitudinal and the torsional vibrations, a new …

This paper presents a study on three types of finite element analyses of high power
ultrasonic transducer by using the finite element commercial software called ANSYS. The …

Ultrasonic instruments and devices are used in an enormous range of activities as well as
biomedicine, and many of them are covered in this book. Its putative raison d'etre is to …

The combination of longitudinal and torsional (LT) vibrations at high frequencies finds many
applications such as ultrasonic drilling, ultrasonic welding, and ultrasonic motors. The LT …
