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 series products provide convenient solutions for non-human use ultrasound application such as education, ultrasound related research, and prototype development. The whole system is on a single PCB board powered by a DC supply, which can be as simple as a commonly used DC adapter with voltage around 7v to 15v, and a current rating above 1A. By connecting to a transducer, which you can make it your own, purchase from us or a third party, you are ready to view ultrasound echo

SonoLab Echo I is designed to support transducers at a center frequency from 1MHz to 10MHz. It transmits square wave burst with predefined peak-to-peak voltage up to 200V and programmable pulse length and pulse repeat frequency (PRF). It has two stages of viable gain amplification with maximal gain of 30dB for each. A trigger output signal is provided through SMA connector and it can be used as an external trigger signal for oscilloscope to display the echo waveform, or a third party high-end data acquisition system to digitize RF data. It also has a SMA trigger-in connector, and the board will transmit ultrasound pulse upon the rising edge of the external trigger (3V to 5V) with a control jumper in the external trigger position.

The echo is digitized at 100MHz, and streamed out at the serial port at 115200 bps. A free Matlab GUI is provided to view the real time echo. Due to the limitation of serial port, a few RF lines will be skipped between the two uploaded RF lines. To increase the line number uploaded per second, the digitizing time window can be adjusted to choose only the interested depth to reduce the data size

Most parameters are predefined in the factory for your convenience and they also can be controlled with a few buttons and a small LCD on the board. All the parameters can also be programmed our free Matlab GUI, the Windows build-in Hyperterminal, or any standard serial port access software. All the control commands are in text format.

The board has a transmitting power safety limit of 2watts. The multiply of transmitting pulse amplitude, pulse length, and PRF is a constant when the load is fixed. So, if you increase one parameter, the maximal allowed value for other two parameters will be lowered automatically.
