| titleOfInvention | Ultrasonic probe and ultrasonic diagnostic apparatus |
| abstract | A vibrator composed of a piezoelectric single crystal is driven by a low-voltage bipolar pulse without depolarization, and high penetration is obtained. A plurality of transducers 15 made of a piezoelectric single crystal are arranged in the distal end portion of an ultrasonic probe, and a preamplifier is connected to each transducer. Each transducer 15 is driven by a low-voltage bipolar pulse supplied from the pulser 34 of the ultrasonic observer 12 and generates ultrasonic waves without causing depolarization. The echo signal output when the transducer 15 receives the reflected wave is amplified by the preamplifier 23 and transmitted to the ultrasonic observation device 12, so that it is not affected by the electric capacity of the cable 29 and the penetration is improved. Can be planned. [Selection] Figure 1 |
