Abstract
A method for compensation for object motion during scan, especially an magnetic resonance imaging (MRI) scan is provided. The method involves taking a first data set corresponding to a first focussed image and adding a number of data points to form a sligthly higher resolution image. The first data set is then used to predict what the next data points would be. The prediction can be performed in k-space, image space or in a hybrid space. The predicted data points arm then compared with the actual data points acquired as a means of determining any displacements. The displacements may be determined by comparing the phases of the actual and predicted data points and the k-space data corrected to compensate for any detected motion.
