1. A method for performing motion compensation in a series of magnetic resonance (MR) images, comprising:
- acquiring a set of MR image frames spanning different points along an MR recovery curve;
generating a motion-free synthetic image for each of the acquired MR image frames using prior knowledge pertaining to an MR recovery curve;
registering each of the acquired MR images to its corresponding generated synthetic image; and
correcting motion within each of the acquired MR image frames based on its corresponding generated synthetic image that has been registered thereto.

Abstract
A method for performing motion compensation in a series of magnetic resonance (MR) images includes acquiring a set of MR image frames spanning different points along an MR recovery curve. A motion-free synthetic image is generated for each of the acquired MR image frames using prior knowledge pertaining to an MR recovery curve. Each of the acquired MR images is registered to its corresponding generated synthetic images. Motion within each of the acquired MR image is corrected based on its corresponding generated synthetic image that has been registered thereto.
