Abstract
Disclosed is an ultrasound diagnostic imaging apparatus including an ultrasound probe which outputs transmission ultrasound toward a subject due to a pulse signal being input and which outputs a received signal by receiving reflected ultrasound from the subject, and a transmission unit which makes the ultrasound probe generate the transmission ultrasound by outputting a pulse signal whose drive waveform is formed of rectangular waves. The frequency power spectrum of the pulse signal has intensity peaks in a frequency band included in a transmission frequency band at −20 dB of the ultrasound probe on a low frequency side and a high frequency side of a center frequency of the transmission frequency band, respectively, and intensity of a frequency region between the intensity peaks is −20 dB or greater with a maximum value of intensity among the intensity peaks being a reference.
