Computer model improves design of ultrasound transducer

4 December 2008

Researcher Koos Huijssen of the Delft University of Technology has developed a computer model that can predict the sound transmission of improved designs for ultrasound transducers. It will lead to better imaging for ultrasound scanners.

Erasmus University Medical Centre and Oldelft Ultrasound are now using this model to design a new sonographic transducer.

Over the past ten years, the images produced by ultrasound or sonography have been vastly improved by making partial use of the nonlinear nature of acoustic waves. Thanks to these developments ultrasound can now be used for a larger group of patients.

Further improvements could be realised by refining the sonography equipment, the transducer that generates the ultrasound and the imaging method. However, this requires a computer model that can accurately predict the transmission of ultrasound. With funding from Technology Foundation STW, Huijssen could develop a model which makes calculations over a three-dimensional area that is larger than existing computer models can handle.

The major challenges in producing such a model are the enormous complexity of the problem and dealing with the required storage capacity and processing power. The model was developed in co-operation with VORtech Computing and has an excellent level of performance.
