1. A method of driving a two-dimensional array ultrasonic probe comprising the steps of:

  • dividing a first set of N transducers in the two-dimensional array ultrasonic probe into Z (<

    N) groups, in which a second set of transducers lying at the same or approximately the same distance from a first focal spot of an ultrasonic beam are in the same group;

    driving the transducers within the first set on a group-by-group basis; and

    generating a first set of signals by adding, within a matrix switch, a second set of signals obtained from one of the Z groups of transducers.
