摘要： A bias gate part supplies a bias current to a transmission pulse generator. The transmission pulse generator receives the supply of the bias current, amplifies an input voltage, and supplies an output voltage obtained by the amplification to array transducer elements. In accordance with the timing of transmitting ultrasound waves from the array transducer elements and the level of the output voltage supplied to the array transducer elements, the bias gate part supplies the bias current to the transmission pulse generator while changing the timing of supplying the bias current.

摘要： An ultrasound probe and ultrasonic diagnosis apparatus that can maintain surface temperature of an ultrasound probe within a safe range, without reduction in performance. The ultrasound probe includes a casing, a transducer, an electronic circuit, and a heat-transfer construction. Elements of the transducer are aligned at one end of the casing and send out ultrasound waves in accordance with their respective delay times. The electronic circuit, disposed in the casing, includes a delay circuit setting delay times and pulsers for generating pulses in accordance with the delay times, the pulses being sent to the transducer. While the electronic circuit is being energized, the heat-transfer construction disposes a member having a low heat conductivity at least either between the electronic circuit and the casing or between the electronic circuit and the transducer. Thereby, heat from the electronic circuit is conducted to the other end of the casing.

摘要： The present embodiment relates to an ultrasound probe having a first ultrasound vibrator group and a second ultrasound vibrator group, comprising a plurality of matrix switches and an adder. The ultrasound probe has a mode to send ultrasound to a predetermined observation point within a subject by the first ultrasound vibrator group, and to receive ultrasound echoes reflected within the subject by the second ultrasound vibrator group. The plurality of matrix switches extract, based on the distance between the second ultrasound vibrator group and the observation point, a plurality of ultrasound echoes having substantially the same phase from a plurality of ultrasound echoes output by the second ultrasound vibrator group. The adder adds the plurality of ultrasound echoes extracted by the plurality of matrix switches for each of the matrix switches and outputs them.
