Abstract:
1. An ultrasonic diagnostic apparatus comprising: a plurality of transducers for transmitting and receiving an ultrasonic wave; transmission pulse generators for generating pulses that allow the transducers to transmit the ultrasonic wave; a transmission power source for supplying power to the transmission pulse generators; and an output side capacitor for stabilizing a voltage of the transmission power source, the transmission power source including: a plurality of mode-specific step-up power sources for outputting a voltage corresponding to each of a plurality of signal processing modes; a power source side capacitor connected to an output side of each of the mode-specific step-up power sources for stabilizing the voltage; and a mode changeover switch provided between the output side of the mode-specific step-up power sources and the output side capacitor for switching between the mode-specific step-up power sources that supply power to the transmission pulse generators, wherein the transmission power source further includes: a power supplying power source connected to an input side of the mode-specific step-up power sources for supplying power; and a power regeneration capacitor with a larger capacity than that of the output side capacitor, one electrode terminal of which is connected to a connection point between the power supplying power source and the input side of the mode-specific step-up power sources and the mode changeover switch, and the other electrode terminal of which is connected to ground, and the mode changeover switch is capable of connecting the power regeneration capacitor, instead of the output side of each of the mode-specific step-up power sources, to the output side capacitor.
