Patent ID: 7828736

Claim:
An electronic scan type ultrasound diagnostic instrument comprising: an ultrasound transducer including a linearly or arcuately arranged array of transducer elements, and adapted to make an electronic scan by sequentially driving a plural number of adjacently located transducer elements into interrelated simultaneous or delayed actions, wherein: said transducer elements are divided into a plural number of transducer assembly units in the direction of said transducer array; each one of said transducer elements is provided with a separate electrode connected with an ultrasound signal transmit/reception line separately from other transducer elements and a common electrode connected with a common electrode of one or a plural number of other transducer elements; further comprising a filmy wiring board arranged in three rows of a same number of contact points running longitudinally along opposite side edges to be connected to respective separate electrodes of said transducer elements and along a center line thereof to be connected with separate electrode wiring cables, wherein said filmy wiring board includes a wiring pattern on front and rear sides thereof, said wiring pattern on the rear side being led out onto the front side by conductive parts inlayed through said filmy wiring board; and said wiring pattern including a number of signal lines separately connected to said separate electrodes, each one of said signal lines being short circuited with a signal line from a transducer element in a corresponding position in another transducer assembly unit and connected together to one same wiring cable.
