Abstract
An improved ultrasound transceiver array for permitting improved imaging is taught. The array may be either a two dimensional array for volumetric imaging or a one dimensional array of elements shaped to permit a more precise beam focus for finer resolution imaging. An Nd:YAG laser is used to machine a workpiece from both ends to produce kerfs which taper inwardly from the transceiving side of the array thereby permitting a stronger ultrasound signal and clearer imaging.
