ABSTRACT:
An electronic scan type ultrasound diagnostic instrument employing an ultrasound transducer which is constituted by an array of transducer elements in a predetermined direction and adapted to drive a plural number of adjacent located transducer elements in simultaneous or delayed action mode. Arrayed transducer elements are divided into a plural number of transducer assembly units in the arrayed direction. Each one of the transducer elements is provided with a separate electrode which is connected with a signal line separately from other transducer elements, and a common electrode which is connected commonly with one or a plural number of transducer elements. A signal line from a separate electrode of a transducer element is short circuited with a signal line from a transducer element in a different transducer assembly unit and connected together to a single wiring cable.
