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.
