Abstract
Provided is an apparatus for processing a magnetic resonance (MR) image, including: an image acquisition unit configured to acquire a plurality of MR images by performing MR imaging on a moving object during temporally consecutive time intervals; a controller configured to sequentially compare two adjacent MR images from among the plurality of MR images to thereby detect an interval during which motion occurs; an image processor configured to calculate a transformation matrix for performing motion correction on at least one MR image corresponding to the detected interval and obtain a motion-corrected MR image by applying the transformation matrix to the at least one MR image; and an output unit configured to display the motion-corrected MR image.

An apparatus for processing a magnetic resonance (MR) image, the apparatus comprising:
- an image acquisition unit configured to acquire a plurality of MR images by performing MR imaging on a moving object during temporally consecutive time intervals;
- a controller configured to sequentially compare two adjacent MR images from among the plurality of MR images to detect an interval during which motion occurs;
- an image processor configured to calculate a transformation matrix for performing motion correction on at least one MR image corresponding to the detected interval and obtain a motion-corrected MR image by applying the transformation matrix to the at least one MR image;
- and
- an output unit configured to display the motion-corrected MR image.
A method of processing a magnetic resonance (MR) image, the method comprising:
- acquiring a plurality of MR images by performing MR imaging on a moving object during temporally consecutive time intervals;
- sequentially comparing two adjacent MR images from among the plurality of MR images to detect an interval during which motion occurs;
- calculating a transformation matrix for performing motion correction on at least one MR image corresponding to the detected interval;
- obtaining a motion-corrected MR image by applying the transformation matrix to the at least one MR image;
- and
- displaying the motion-corrected MR image.
A non-transitory computer-readable medium method including program code that, when executed by one or more processors, causes a magnetic resonance (MR) image processing apparatus to:
- acquire a plurality of MR images from MR imaging performed on a moving object during temporally consecutive time intervals;
- sequentially compare two adjacent MR images from among the plurality of MR images to detect an interval during which motion occurs;
- calculate a transformation matrix for performing motion correction on at least one MR image corresponding to the detected interval;
- obtain a motion-corrected MR image by applying the transformation matrix to the at least one MR image;
- and
- output the motion-corrected MR image.
