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 ...
Predictions of nonlinear ultrasound beams of a medical phased array transducer, steered at 0, 22.5 and 45 degrees, and generated by a forward-wave and a full-wave numerical model are presented. The results from both models show a good agreement in the unsteered situation and in a ...
A full wave 3d time domain algorithm is presented that calculates the nonlinear acoustic wavefield of medical phased array transducers emitting an arbitratily steered, focused apodized beam. The algorithm can be used for computer simulation studies of the occuring second and high ...
A generalized theoretical framework for acoustic, electromagnetic and elastodynamic waves would give fruitful insights into equivalent phenomena in these physical domains and would form a basis to draw up general analytical or numerical solution methods. In this contribution we a ...
