Abstract
An ultrasound diagnostic apparatus includes an ultrasound probe, a transmission unit for transmitting an ultrasound signal to an object to be examined via the ultrasound probe, a reception unit for processing a signal received by the ultrasound probe, and an image generating unit for generating an image on the basis of the received signal processed by the reception unit, wherein the transmission unit has a function of transmitting the ultrasound signals with varying frequency plural times in an identical direction at predetermined time intervals. The ultrasound signal transmitted plural times includes a first waveform in which the frequency increases and a second waveform in which the frequency decreases, and the reception unit has a function of phasing and adding received signals respectively corresponding to the first waveform and the second waveform, whereby, in tissue harmonic imaging, the penetration is improved, while the resolution is maintained.
