1. Method for acquiring MR image data pertaining to a moving organ, said organ executing motion between a first extreme and a second extreme position, said method comprising the steps of: registering a scout film of the organ concurrently with the registration of at least one signal that is indicative for the position of such organ as measured with the scout-film acquiring real-time MR image data in at least one scan-plane of said organ, whereby the position of said scan-plane is adjusted depending on the concurrently measured signal estimating the position of said organ between its extreme positions, characterized in that a plurality of scan-planes are employed whereby 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 as measured with the scout-film; and that 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.
