Ultrasound diagnostic apparatus and method for tracing movement of tissue
First Claim
1. An ultrasound diagnostic apparatus comprising:
- a transmitting and receiving unit configured to transmit an ultrasound wave to a target object in sequence and to receive the ultrasound wave as ultrasound data reflected from a certain region of the target object including a short axis direction blood vessel in sequence;
a first memory unit configured to store the received ultrasound data in sequence;
an image generation unit configured to generate an ultrasound image as a sectional image of the short axis direction blood vessel based on the received ultrasound data;
a display unit configured to display the ultrasound image generated by the image generation unit;
a region of interest setting unit configured to set a plurality of regions of interest on an inner wall and an outer wall of the blood vessel in the ultrasound image displayed by the display unit at a designated time, wherein the regions of interest are generated from the ultrasound data stored in the first memory unit;
a tracing unit configured to trace movement of tissue in the target object corresponding to the regions of interest set in the ultrasound image from the designated time to sequentially following thereafter; and
a second memory unit configured to store information of the movement of the tissue for a predetermined duration based on the movement of tissue traced by the tracing unit.

Abstract
An ultrasound diagnostic apparatus includes a transmitting and receiving unit that transmits an ultrasound wave to a target object in sequence and receives the ultrasound wave as ultrasound data reflected from the target object including a blood vessel. A first memory unit stores the received ultrasound data. An image generation unit generates an ultrasound image as a sectional image of the blood vessel. A display unit displays the ultrasound image. A region of interest (ROI) setting unit sets a plurality of ROIs on an inner wall and an outer wall of the blood vessel at a designated time. The ROIs are generated from the ultrasound data. A tracing unit traces movement of tissue in the target object corresponding to the ROIs set from the designated time to sequentially following thereafter. A second memory unit stores information of the movement of the tissue for a predetermined duration.

20. A method for tracing movement of tissue, the method comprising:
-
transmitting an ultrasound wave to a target object in sequence; receiving the ultrasound wave as ultrasound data reflected from a certain region of the target object including a short axis direction blood vessel in sequence; storing the received ultrasound data in sequence; generating an ultrasound image as a sectional image of the short axis direction blood vessel based on the received ultrasound data; displaying the ultrasound image; setting a plurality of regions of interest on an inner wall and an outer wall of the blood vessel in the displayed ultrasound image at a designated time; tracing movement of tissue in the target object corresponding to the regions of interest set in the ultrasound image from the designated time to sequentially following thereafter; and storing information of the movement of the tissue for a predetermined duration based on the traced movement of tissue.
