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. An ultrasonic probe containing the inventive array can be quickly switched between two and three dimensional imaging modes to produce both a three dimensional image and a two dimensional image in real time.Other References
