ABSTRACT:
A method for compensating for inoperative transducer elements in an ultrasound transducer. The transmit voltage of the driving signals applied to transducer elements that are adjacent an inoperative element is increased to compensate for the inoperative element. Preferably, a linear interpolation used whereby the power/gain of the signals to be applied to the inoperative element is divided equally among the adjacent operative elements. If an inoperative transducer element is adjacent more than one inoperative element, then the gain of the operative transducer element is increased accordingly for each such inoperative element. In addition, the gain of the echo signals produced by the adjacent transducer elements is increased to compete for the inoperative element.
