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 image diagnostic apparatus includes: a power source control section that supplies power to a power source section which performs supply of power to each part of the ultrasound image diagnostic apparatus; a battery that supplies the power to the power source control section: an external power supply section that supplies, to the power source control section, the power supplied from outside of the ultrasound image diagnostic apparatus; and a power supply control section that controls supply of power from the battery and the external power supply section to the power source control section based on an operation state of the ultrasound image diagnostic apparatus and the presence or absence of the power supplied from the external power supply section.

Abstract: Control device 10 of an ultrasound diagnostic apparatus includes a hardware processor that sets, among a plurality of operation modes in which pulse waveforms of ultrasound pulses to be transmitted are different from one another, at least first and second operation modes for which observation results are to be simultaneously displayed on a screen, sets at least one operation type that defines transmission timing of ultrasound pulses, and sets a switching frequency of a switching signal.
