摘要:
A method, a system, and a computer-readable medium are provided which perform motion correction of image data. A first set of data and a second set of data of k-space data of an object to be imaged are received. The first set of data and the second set of data include a plurality of phase encoded lines that encompass the object to be imaged. The first set of data correlates with the second set of data. A cross-correlation is calculated by multiplying the first set of data and the second set of data in k-space. A value of the motion of the object to be imaged that occurred between acquisition of the first set of data and acquisition of the second set of data is calculated using the cross-correlation. The second set of data is corrected using the calculated value to remove the motion. The correction process is repeated until the k-space data is completely processed.
