摘要： 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.

摘要： There is provided first storage means (3) for storing digital reception beam data converted from a reception beam formed from an ultrasonic received signal; first control means (2) for controlling reading and writing of data from/in the first storage means; a filter coefficient calculation portion (5) for calculating a filter coefficient based on information on the reception beam, the information including a positional relationship between the reception beam and a transmission beam; and a first spatial filter operation portion (4) for subjecting each of a plurality of the reception beam data including data of beams received in parallel from a single transmission beam to filtering processing for reducing a difference in image quality between adjacent beams based on the filter coefficient. Image data output from the first spatial filter operation portion are converted into scanning of a display monitor (8) so as to display an image on the display monitor. In an ultrasonic diagnosis apparatus having a parallel reception function, it is possible to display a high-quality ultrasonic image in which stripes are generated less in a direction in which acoustic lines are arranged and that is well defined in detail.
