Ultrasound diagnostic apparatus
First Claim
1. An ultrasound diagnostic apparatus comprising:
- transmitting means including an ultrasound probe for transmitting a ultrasound pulse beam from the ultrasound probe into a body;
receiving means including the ultrasound probe 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;
delay controlling means for controlling an acoustic line direction of transmission and reception of the ultrasound pulse beam and the ultrasound echo beam;
phase detection means for subjecting the electric echo signal to phase detection to generate a phase-detection result signal;
tissue velocity calculating means for calculating a velocity of a tissue in the body from the phase-detection result signal; and
display means for indicating the calculated velocity of the tissue;
wherein the delay controlling means comprises means 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.

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.

10. An ultrasound diagnostic apparatus comprising:
-
first means for transmitting a first ultrasound pulse beam into a body toward an object within the body along a first direction;
second means for receiving a first ultrasound echo beam caused by reflection of the first ultrasound pulse beam at the object and coming from the object along the first direction;
third means for transmitting a second ultrasound pulse beam into the body toward the object within the body along a second direction angularly different from the first direction;
fourth means for receiving a second ultrasound echo beam caused by reflection of the second ultrasound pulse beam at the object and coming from the object along the second direction;
fifth means for calculating a velocity of the object along the first direction from the first ultrasound echo beam received by the second means; and
sixth means for calculating a velocity of the object along the second direction from the second ultrasound echo beam received by the fourth means. - View Dependent Claims (11, 12)
