Abstract
A small ultrasound diagnostic device is provided at a low cost that enables the appropriate control by a single power supply unit so as to give a predetermined transmission power to a driving waveform different for each mode without excess or deficiency and without affecting properties of the driving waveform. The ultrasound diagnostic device includes: an ultrasound generation unit () that transmits ultrasound; a waveform generation unit () that generates a single pulse or a burst pulse whose duty factor is variable in units of a time that is a period corresponding to a frequency outside a frequency band of the ultrasound generation unit () so as to drive the ultrasound generation unit (); and a single power supply unit () that determines an amplitude of a driving waveform generated by the waveform generation unit (). Thereby, an acoustic power of the transmitted ultrasound can be controlled without making the transmission amplitude variable.
