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 Echo I Specification
  1. Power input
    1. Voltage: 7 - 15V DC
    2. Current: 1A or above
  2. Ultrasound pulse at 50W load
    1. Amplitude: 15 - 100V.
    2. < <
      A 2 MHz pulse with 100 volt peak to peak A 2 MHz pulse with 200 volt peak to peak
      A 5 MHz pulse with 100 volt peak to peak A 10 MHz pulse with 100 volt peak to peak
    3. Burst Length: 1 - 256
    4. Maximal Duty Factor: 2Watt/(Amplitude2 /Load), at 100V amplitude, Duty_Max is 0.01, or 1%.
    5. PRF Max = (Center_frequency) * 2* Load / Amplitude2  /  Burst_length

                                                              i.      For example, at 1MHz, 100V, when burst length is 1, the maximal allowed PRF is 1e6 *2*50/1002  /1 = 10 kHz

                                                            ii.      With above parameters, at 10MHz, the maximal allowed PRF is 100KHz.

                                                          iii.      WARINING: 2Watts may have some unsafe effects on human or animal. If you use it on human or animal experiments, it is your responsibility to check the FDA or other related regulatory standards.

  1. Receiver
    1. Total gain: 0 - 60 dB
    2. Bandwidth: 90 MHz
  2. AD converter
    1. Clock: 100MHz
    2. Width: 8 bit.
    3. Input range: 0 - 1.5V.
  3. Depth control 
    1. Start Depth: AD will start to digitize data when the echo from Start_Depth returns to transducer. The default value is 50mm / Center_frequency (MHz). It is 5mm at 10 MHz.
    2. Stop Depth: AD will stop digitized data when the echo from Stop_Depth returns to transducer. The default value is 500mm  / Center_frequency (MHz). It is 50 mm at 10 MHz.
    3. Effects on PRF: PRF_Max = 1 / (Stop_depth * 2 /C) . C is sound speed, with a default value of 1540m/s.
  4. Serial port control
    1. Baud rate: 115200 bps.
    2. Stop bit: 1
  5. Trigger out: 3.3V, 50ns duration.
  6. Trigger in: 3.3v - 5V, no less than 100ns duration.
  7. Dimensions: length: 8''; width: 5.4''; height: 2''
  8. Environment: 10o C - 30o C
