Abstract
An ultrasonic imaging array has two independent, interleaved linear subarrays occupying a common array face. The subarrays are independently steerable and focusable in different imaging planes. The subelements making up the elements in of the subarrays is preferably quadrilateral. Adjacent subelements in each element are electrically connected via an interconnect portion such that the interconnect portion connecting each pair of adjacent subelements in each element is substantially linear and is aligned with the diagonals of the adjacent subelements. A preferred acoustic lens is curved in both azimuth and elevation directions, whereby the subarrays are independently focusable. By transmitting in one plane and simultaneously receiving in a different, orthogonal plane, a system including the array can image a 3-D region of interest (ROI). In a volumetric embodiment of the invention two orthogonal B-mode images of a structure within the ROI are displayed simultaneously. The user may then trace the outlines of the images and the system therefrom calculates the volume of the structure.
