A diagnostic ultrasound imaging device is connectable to an ultrasound probe which has a piezoelectric element. The diagnostic ultrasound imaging device includes an image generation unit, a display unit, a touch panel and a control unit. The image generation unit generates an ultrasound image on the basis of a reception signal obtained from received reflected ultrasound from a subject. The display unit displays the generated ultrasound image on a display screen. The touch panel detects an operation on the display screen. When the touch panel detects on the displayed ultrasound image an end of a cursor movement operation to move a cursor, the control unit displays near the moved cursor an operation button to activate a predetermined function.
