Abstract
Provided is a method for compensating for tissue motion during magnetic resonance (MR) imaging, and an apparatus for use thereof. The method includes acquiring a plurality of short-time MR scan images; selecting a reference scan image from the acquired plurality of short-time MR scan images; defining a set of transformation images based on the acquired plurality of short-time MR scan images other than the selected reference scan image; registering the reference scan image and the defined set of transformation images; calculating an average of aligned, registered images of the defined set of transformation images; and generating a motion-corrected image based on the calculated average.

A method for compensating for tissue motion during magnetic resonance (MR) imaging, the method comprising:
- acquiring a plurality of short-time MR scan images;
- selecting a reference scan image from the acquired plurality of short-time MR scan images;
- defining a set of transformation images based on the acquired plurality of short-time MR scan images other than the selected reference scan image;
- registering the reference scan image and the defined set of transformation images;
- calculating an average of aligned, registered images of the defined set of transformation images;
- and
- generating a motion-corrected image based on the calculated average.
A method for compensating for tissue motion during magnetic resonance (MR) imaging, the method comprising:
- acquiring a plurality of short-time MR scan images;
- selecting a reference scan image from the acquired plurality of short-time MR scan images;
- defining, using a first registration process, a first set of transformation images based on the acquired plurality of short-time MR scan images other than the selected reference scan image;
- defining, using a second registration process, a second set of transformation images based on the acquired plurality of short-time MR scan images other than the selected reference scan image;
- registering the reference scan image and the defined first and second sets of transformation images using the first registration process and the second registration process;
- calculating an average of aligned, registered images of the defined first and second sets of transformation images;
- generating first and second motion-corrected images based on the calculated average;
- and
- comparing the first and second motion-corrected images.
