Abstract
An ultrasound diagnostic apparatus includes a transmitting device having an ultrasound probe. The transmitting device operates for transmitting a ultrasound pulse beam from the ultrasound probe into a body. A receiving device includes the ultrasound probe. The receiving device operates for receiving an ultrasound echo beam caused in the body, and converting the received ultrasound echo beam into a corresponding electric echo signal via the ultrasound probe. A delay controlling device is operative for controlling an acoustic line direction of transmission and reception of the ultrasound pulse beam and the ultrasound echo beam. A phase detection device is operative for subjecting the electric echo signal to phase detection to generate a phase-detection result signal. A tissue velocity calculating device operates for calculating a velocity of a tissue in the body from the phase-detection result signal. A display device is operative for indicating the calculated velocity of the tissue. The delay controlling device is operative for changing the acoustic line direction of transmission and reception of the ultrasound pulse beam and the ultrasound echo beam with respect to a same object.
