Ultrasound Transducer Simulation Page
BioSono provides a cyberspace (www.biosono.com) where researchers, engineers, and students can find useful reference and educational materials, conduct acoustic simulation, post questions on design and development, and get answers. The online KLM based transducer acoustic stack simulation, which is currently free, can help you choose piezoelectric, matching and backing material, and a tuning electrical network. The output from the model includes electrical transmit impedance, acoustic receive impedance, and the impulse or pulse-echo response. The ultrasound beam profile simulation provides the calculated transmitted ultrasound pressure field under certain excitation for a given transducer aperture in a number of different geometrical configurations, including circular elements (flat and concave piston), rectangular elements, linear arrays, convex arrays, and 2D arrays. The simulation is based on Field II, which is a free program that utilizes the spatial impulse response method, and has been validated by many researchers for accuracy. In addition to the web based acoustic simulation, we also provide pulse-echo system, transducers, and customized design and develop services.

Hello,

Great website! I am currently investigating the use of focused ultrasound. I was wondering how I could calculate Depth of Focus for a Cylindrical Transducer. The ultrasound calculator has for Concave Piston but not for cylindrical piston. Is there a way of using the calculator to get the depth of focus for a cylindrical piston? I assume the -3db beam width will be the length of the pzt (longitudinal direccion) plus a little more but what i really need to calculate is the depth of focus? Thanks for any help in advance.

Also, is it possible to make your own cylindrical pzt4 or is it quite complicated. Or maybe other piezoelectric compounds can be used that are appropriate for focused ultrasound (composites). Any help appreciated.
