摘要： A plurality of signal transmitters are respectively configured to produce a pulse current by repeatedly switching the connection state of a switching element. A plurality of ultrasonic transducers are respectively configured to transmit an ultrasonic pulse to a subject to be examined upon receiving said pulse current, and to produce a receiving current upon receiving the reflected wave. A signal receiver is configured to receive said receiving current. A test signal generator is configured to produce a test signal and to output said test signal to a connection point of said signal transmitter, said ultrasonic transducer, and said signal receiver by switching said connection state of said switching element to a state through which said test signal is conducted.

摘要： An ultrasonic diagnostic apparatus includes plural ultrasonic transducers, a catheter signal detection unit and a position detection unit. The plural ultrasonic transducers are arrayed two-dimensionally for transmitting and receiving ultrasonic waves to and from an object. The catheter signal detection unit is configured to acquire a reception signal of a frequency modulated continuous wave from reception signals from at least three of the plural ultrasonic transducers. The frequency modulated continuous wave is transmitted from a catheter inserted in the object. The position detection unit is configured to detect a position of the catheter based on the acquired reception signal of the frequency modulated continuous wave.

摘要： Real-time display of a three-dimensional ultrasonic image in which there is little time delay, power required for transmission of an ultrasonic wave is reduced, and heterogeneousness of received beams is almost solved is performed by executing multi-beam reception while performing frequency demodulation of a reflected wave obtained as a result of transmission of a frequency-modulated continuous ultrasonic wave to the subject body. As a demodulation method, for example, a multi-phase demodulation method of obtaining the distance resolution in multi-beam reception by performing (multi-phase) demodulation while changing the phases of transmission modulation and reception modulation for every range in the range direction (beam direction).

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.
