Koos Huijssen went in search of a computer model that could predict the behaviour of ultrasonic waves. Over the past ten years, the images produced by ultrasound or sonography have been vastly improved by making partial use of the non-linear 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, Koos 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 the company VORtech Computing and it has an excellent level of performance.
