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.

Why need ultrasound?

. Your explanation was cenlriaty the least complicated to fully grasp. I usually get annoyed whenever individuals discuss issues that these people plainly do not know about. You were able to hit the nail on the head and spelled out every thing without complication. Possibly, people could take a sign. Will likely be back to acquire even more. Many thanks

Because Ultrasound is different from sound, it has much higher frequency, and the higher the frequency, the shorter the wavelength. For sound, with frequency is lower than 20kHz, the wavelength is very long, and thus the sound source is relative small compared to the wavelength, and in this way it becomes a point source, the sound wave spread in all the directions equally, no directivity. For ultrasound, for example, at 10MHz, the wavelength is only 0.15mm, and the energy will propagate as a beam, like light from a flash light.
