title: Finite element simulation and modeling of 2-D arrays for 3-D ultrasonic imaging.
abstract: Issues of modeling and design of 2-D arrays in three dimensions with finite element code are discussed. These ultrasonic arrays are used for real time dynamic imaging of the heart. Topics include optimization, sensitivity, and performance and methods to speed up the run times required for computer simulations of large three-dimensional models. Empirical results from 45 x 45 2-D arrays are also presented.
