Abstract	Three-dimensional (3-D) simulations of ultrasound image formation can be used to investigate quantitative relationships between characteristics of ultrasound images and the microscopic structure of tissue, which can improve tissue characterization methods. However, such simulations involve high computational complexity which limits their use in imaging research. A parallel 3-D ultrasound simulator is presented that uses an efficient numerical method to compute acoustic propagation. The simulator runs on computer clusters and enables accurate 3-D simulations with short running times. Ultrasound images of a tissue-mimicking phantom created using the simulator show realistic 3-D refraction artifacts. The parallel execution time of a simulated image using 20 cluster nodes was 18.61 hours compared to a serial execution time of 357.50 hours.
