Abstract: A model of a medical ultrasound imaging system can be broken into four major subsystems: the transducer, the array, the beamformer, and display system. In this work, each sub- system is modeled separately and combined to simulate the complete system. Transducer elements are modeled as three port systems with two mechanical ports and one electrical port. The array is modeled as a product of a point source array and finite radiating elements. The beamforming system is modeled as a frequency domain beamformer with depth focusing, utilizing a parallel computing architecture. Each of these systems offers flexibility to model a one dimensional linear phased array, a 1.5D array or a two dimensional array, or an array of arbitrary shape. !12
