1. A method for acquiring a motion corrected image with a magnetic resonance imaging (MRI) system, the steps comprising: a) acquiring a k-space data set by repeating an imaging pulse sequence with the MRI system to sample k-space as a series of k-space segments; b) reconstructing a series of tracking images from the corresponding series of acquired k-space segments; c) calculating the movement of point objects in the subject during the acquisition of each k-space segment by detecting the movement of corresponding point spread objects in each tracking image; d) calculating a corrective phase shift for each k-space segment based on the detected movement during the acquisition of each k-space segment; and e) reconstructing an image using the corrected k-space segments.
