Computer simulation plays a significant role in the development of diagnostic ultrasound sound systems. Traditional calculation methods for continuous wave ultrasound calculations converge slowly when applied to transient wave propagation. Fast and accurate calculation methods are developed and discussed in this thesis to improve the performance of computing transient ultrasound wave propagation. B-mode imaging is widely used in practical diagnostic ultrasound applications. The imaging system is based on the pulse echo model. Transient ultrasound pulse waves are generated from the transducer, and echo signals are received to generate images. Traditional imaging simulation methods use the impulse response method, which requires high sampling frequencies to reach acceptable accuracies. By employing a convolutional simulation model and using fast and accurate transient ultrasound wave calculation methods, the simulation performance can be improved significantly both in image quality and simulation speed.
