S.S. Khalafvand, J.D. Voorneveld, H.W. Mulder, A. Haak, F.J.H. Gijsen, J.G. Bosch, N. de Jong, S. Kenjeres (2016), “Numerical modelling of 4D left ventricular blood flow using computed tomography imaging and computational fluid dynamics”, Proceedings of the Virtual physiology hu ...
In this paper, a programmable time-gain-compensation amplifier dedicated to a 2D piezoelectric ultrasound transducer is presented. It uses an open-loop amplifier structure consisting of a voltage-to-current converter and a current-to-voltage converter. The circuit has been design ...
In order to predict the pulsed, nonlinear ultrasound field from medical phased array transducers, a numerical model has been developed that computes this field in a large-scale, three-dimensional configuration. The model is free of an assumed (quasi-plane) directionality in both ...
