Abstract
Apparatus and method for generating and displaying undistorted images of a field of view containing undesirable motion and/or time varying magnetic field inhomogeneities, uses a time series of magnetic resonance (MR) image signals, corresponding to a time series of MR images, generated by a single-shot imaging technique without shot-to-shot phase encoding. Signals are stored and analyzed to identify missing and/or deteriorated images (including image portions, image lines or image line segments). Identified missing and/or deteriorated images are compensated for by replacement, repair or otherwise. MR image signals representative of a specified time series are selected. Then, selected signals of corresponding portions of the field of view are averaged. The invention may be used to present: a continuously updated time series of images; a time series of images with only a specified portions of the image updated in each display; or an entire time series of images re-created in any desired sequence.
