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.

Hi, could you please tell me how to calculate the delay time in ultrasound calculator.

e.g. Linear Array
3 Center Frequency: MHz
25 Kerf: um
1 Element Width: mm
3 Element Height: mm
11 Total Element Number
20 Electric Focal Depth: mm

Your results:
Element Accept Angle: 29.426751592356684 deg
F_number: 1.7738359201773836
-3dB Lateral Beam Width: 0.9105691056910569 mm
-3dB Elevation Beam Width: 2.0533333333333332 mm

Delay for all the elements:
No. 1 : 0 ns
No. 2 : 149.52991417904647 ns
No. 3 : 267.0073640105088 ns
No. 4 : 351.56703733347865 ns
No. 5 : 402.56676876729057 ns
No. 6 : 419.6111847002333 ns
No. 7 : 402.56676876729057 ns
No. 8 : 351.56703733347865 ns
No. 9 : 267.0073640105088 ns
No. 10 : 149.52991417904647 ns
No. 11 : 0 ns

thank you!
