Abstract: An ultrasound diagnostic apparatus includes a signal generation unit, amplitude adjustment units and a control unit. The signal generation unit generates a pulse signal with a predetermined voltage amplitude. The amplitude adjustment units individually change the voltage amplitude of the pulse signal so as to output pulse signals with individual voltage amplitudes to their respective transducers. The control unit controls change amounts of the voltage amplitude made by the amplitude adjustment units. Each amplitude adjustment unit includes resistive elements and switching units which change a conductive state of their respective resistive elements. The control unit outputs a control signal to set a combination of ON and/or OFF of the switching units to change a load of the amplitude adjustment unit so as to apply to the transducer a voltage for an amplitude of ultrasound which is transmitted from each of the transducers.

Abstract: An ultrasound diagnostic apparatus includes the following. A deflection controller generates delay time information to make phases of reception signals input to channels uniform according to a deflection angle. A channel selector selects a channel in which the reception signal is turned on or off so that the phases of the reception signals input to channels are different and which generates channel selection information. A reception delay interrupter provides the delay amount to the reception signal and which turns on or off the reception signal. An adder adds the plurality of reception signals which are provided with the delay amount and turned on.
