Abstract
The present invention relates to an apparatus for estimating and compensating a motion in forming an ultrasound synthetic image. The apparatus includes a transmit/receive control unit, an auto correlation unit and an image motion estimation and compensation unit. The transmit/receive control unit may set a plurality of scan lines, define sequential indices upon the scan lines, and set a transmit order of a transmit beam for the scan lines in a non-sequential manner in which increment and decrement of the indices of the scan lines are repeated. Then, the transmit/receive control unit may transmit the transmit beam to a target object based on the set transmit order to obtain a plurality of receive beams in response to each transmission of the transmit beam. The auto correlation unit may group the receive beams to an increment group corresponding to an increment direction and a decrement group corresponding to a decrement direction and perform auto correlation upon the receive beams. The auto correlation unit may apply weights to the auto correlation results and sum the weight-applied auto correlation results to there provide phase information. The image motion estimation and compensation unit may estimate and compensate a motion of a target object based on the phase information.
