Abstract
An ultrasonic imaging method and apparatus are described for electronically scanning a volumetric region using a two dimensional array of transducer elements coupled to a beamformer. Elements of the array are actuated to transmit ultrasonic energy into the volumetric region. Echo signals are received by elements of the array in response to the transmitted ultrasonic energy. Beams are formed which sample the volumetric region that allows choices of size, location and geometry shapes such as in one of a circular and elliptical beam pattern.
