The simulation of realistic medical ultrasound imaging is a computationally intensive task. Although this task may be divided and parallelized, temporal and spatial dependencies make memory bandwidth a bottleneck on performance. In this paper, we report on our implementation of an ultrasound simulator on the Cell Broadband Engine using the Westervelt equation. Our approach divides the simulation region into blocks, and then moves a block along with its surrounding blocks through a number of...[Show more]
