ABSTRACT:
A transducer element alignment structure for use with a two-dimensional transducer to form an ultrasonic three-dimensional image performs a three-dimensional scanning by using the smallest number of elements, wherein a number of transducer elements are aligned on a plurality of concentric circular grids. The first element is aligned at a location on each grid and the other elements are aligned at a respective location so that the circumferential distance between the elements has the same arc length, to thereby construct a simple system and effectively form ultrasonic three-dimensional images.
