Abstract:
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.
