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.

摘要： According to one embodiment, an ultrasonic probe includes a probe unit and cooling unit. The probe unit is obtained by arranging, in a housing, a transducer unit which transmits and receives ultrasonic waves with an object to be examined, an electronic circuit unit which is connected to the transducer unit and performs electrical signal processing, and a heat transfer member which is made of a material having a heat transfer coefficient higher than that of the electronic circuit unit, and transfers heat of the electronic circuit unit to a housing surface. The cooling unit is detachably mounted on the housing of the probe unit, and cools the heat transfer member by passing a coolant in a channel formed inside the cooling unit.

摘要： An ultrasonic diagnostic apparatus has an ultrasonic probe for transmitting and receiving an ultrasonic wave at a group of a plurality of ultrasonic vibrators arranged in an array form to and from a subject and incorporating a preamplifier groups for amplifying the resulting weak ultrasonic echo received after obtaining tissue information about the subject. The ultrasonic vibrator group has a first area to which a first amplifier group is to be connected and a second preamplifier group to which a second amplifier group is to be connected. In an operating mode to cease the first preamplifier group from operating, a control circuit switches to supply the bias current being supplied to the first preamplifier group over to the second preamplifier group.
