Abstract
The focusing and steering properties of pulsed 2-D arrays were theoretically investigated to characterize the parameters required for medical imaging, such as element size, spacing, and number of elements. Details of the computational methods employed are presented, and the steered-beam properties of wideband 2-D arrays are discussed. An element-reduction scheme, using a sparse array with elements randomly distributed over a square aperture, is examined
