Method software and apparatus for acquiring MR-image data pertaining to a moving organ

A method for acquiring MR image data pertaining an organ, moving between a first extreme and a second extreme position such as in motion due to breathing of the patient to be examined. A scout film is registered of the organ concurrently with the registration of a signal that is indicative for the position of such organ. Real-time MR image data are acquired in at least one scan-plane of said organ, and the scan-plane is adjusted depending on the concurrently measured signal estimating the position of said organ. Several scan-planes are employed. For each individual scan-plane of said plurality of scan-planes, its position as a function of time is defined in relation to pre-selected organ-positions is measured with the scout-film. During the acquisition of the real-time MR image data the respective scan-positions are each individually adjusted, each scan-plane position thereby depending on the signal indicative for the position of the organ. In particular the invention is used in cardiac MR-imaging.
