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.

SonoLab supports boot loader feature. The latest version of software can be download from here and loaded to the board through the mini-USB port that you usually communicate with PC, by the following steps:

  1. Create a folder under you root directory: "C:\boot"
  2. Right click here and choose "Save Target As.." to download the latest version of software to "C:\boot ", if you don't have it yet
  3. Download the bootloaderto "C:\boot", if you don't have it yet
  4. Find the COM number on your computer:
    • Connect the board to PC throug a USB cable, don't power on!
    • Open your "Device Manager", and show the following screen:
    • COM number is shown followed "USB Serial Port". For example, in the above graph, it will be "COM5".
  5. Run "cmd" to enter command mode from "start":
  6. Type "cd\boot" enter "c:\boot" directory:
  7. Type "BLdr -i COMx -b 115200 Sys.hex ", DO NOT hit enter !
  8. Turn on SonoLab
  9. Hit enter within 5 seconds. Bootloader starts, take up to 15 seconds to finish
  10. The following screen will be shown once is completed:
  11. Congratulations, your software update is completed!
