Abstract
An ultrasonic 2D array has elements extending in two dimensions which can be individually controlled and operated to form a 2D array for scanning a volumetric region in three dimensions. Individual ones of the elements can also be selected and operated together to form a 1D array for scanning a planar region in two dimensions. The array transmits scanlines to scan the volumetric region and the planar region in a time interleaved manner with the frame rate of the planar region be higher than that of the volumetric region. A spectral display may also be produced of a sample volume located in the planar region.
