Abstract: An ultrasound diagnostic apparatus configured in a manner connectable to an ultrasound probe includes a transmission unit configured to control supply of a transmission electric signal to transmit ultrasound from the ultrasound probe to a subject, a reception unit configured to acquire a reception signal which is based on reflected ultrasound received by the ultrasound probe, an ultrasound image generation unit configured to generate tomographic image data of the subject based on the reception signal, a movement reception unit configured to acquire movement information of the subject, a dynamic schematic view data generation unit configured to generate, based on the movement information, schematic view image data illustrating a movement of the subject in a schematic view, and a display processing unit configured to generate composite image data in which the tomographic image data and the dynamic schematic view image data are compounded based on time information.

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 (1) that transmits ultrasound; a waveform generation unit (2) 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 (1) so as to drive the ultrasound generation unit (1); and a single power supply unit (3) that determines an amplitude of a driving waveform generated by the waveform generation unit (2). Thereby, an acoustic power of the transmitted ultrasound can be controlled without making the transmission amplitude variable.
