1. An ultrasonic imaging apparatus comprising:

  • an ultrasonic probe;

    a plurality of acoustic elements configured and arranged to form a two-dimensional array, said two-dimensional array configured and adapted to fit within the ultrasonic probe wherein said plurality of acoustic elements includes at least two active acoustic elements capable of generating acoustic pulses and/or receiving echo signals; and

    a beam controller coupled to said two-dimensional array, said beam controller capable of driving the at least two active acoustic elements to produce said acoustic pulses originating from the two active acoustic elements for impinging an acoustic target to generate the echo signals, and having associated circuitry configured for controlling directional movement of said acoustic pulses by a combination of tractor treading and beam steering.
