2D-Array transducers are used in real-time 3D ultrasound imaging. Appropriate design of the received and emitted beam pattern from 2D-Array transducers is the aim of simulation of the beam pattern. In most methods of the simulation of acoustic fields, the far-field approximation was applied in order to increase the speed of the calculation. In this paper a new method that without applying any approximation converts the two dimensional Rayleigh integral over the transducer surface to one dimensional integral expression is used. It has shown proper speed and good accuracy both in near-field and in far-field. So it will be useful in intravascular sonography or low depth imaging, where the desired tissue is very near to the transducer. Also it can be used for optimizing array parameters in designing stage and also for education and research purposes. Simulation results are shown for different parameter settings to evaluate the effects of every parameter on the field of 2-D arrays.
