Abstract
A method of imaging a patient with an MRI scanner (10) includes imaging a region of interest of the patient with the MRI scanner (10) and acquiring image data resulting from the imaging. An image of the region of interest is reconstructed from the image data. The method also includes generating navigator echos during the imaging, collecting the navigator echos and deriving, from each navigator echo, a measurement of patient motion experience during the imaging. A historical record of the measurements is maintained. Parameters for the acquisition of image data are selected to compensate for motion, or specific image data is selected for reconstruction, based on the historical record.
