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.

You are welcome to the ultrasound discussion area. Your questions will be answered if they fall into the following categories:
  • Piezo-electrical material
  • Basic acoustic or ultrasound
  • Ultrasound imaging theory
  • Ultrasound transducer simulation, design and fabrication
  • Ultrasound beamforming architecture, algorithm, and related electronics.
  • Ultrasound transceiver, analog front-end.
  • Ultrasound imaging display algorithm

Hello,

storing new materials into the data base does mostly not work: In much cases, the properties are not stored correctly, but in the new material are properties of another material. Even if i repeat storing the material data, the results are not predictible.

Kudos! What a neat way of thinnkig about it.

In the Table for PZT-5A (mostly used) vL 4445 vS 3970 is it true ? THX

We did several tests on matching, active and backing materials and so far no issue was found. We will continue investigate and inform you if we found anything.
It will be helpful if you give more details.

Thanks for the information
We are going to investigate it.
