titleOfInvention Ultrasonic wave energy electronic b-scan imaging apparatus
abstract A transducer (102) comprising a longitudinal bar of piezoelectric material (200) having one longitudinal face substantially covered with a first electrode (202) and the opposite longitudinal face in contact with a predetermined plural number of separate electrodes (204-1, 204-2, ... 204-n) spaced along the length thereof, permits all detected echoes to be processed by a single low input impedance amplifier (206) permanently coupled to the first electrode.
