Abstract
An MR system acquires, over multiple heart cycles, image datasets representing multiple image slices of an anatomical region of interest of a patient. In the device, an RF signal generator and a magnetic field gradient generator provides an RF pulse and magnetic field gradient sequence for RF signal excitation of the region of interest and for acquiring RF data following the signal excitation. The sequence comprises, a first sequence occurring substantially immediately after the acquisition of image data using a readout magnetic field gradient. The first sequence includes an RF pulse with a predetermined flip angle followed by a magnetic field gradient pulse for reducing field magnetization to substantially zero. The first sequence is preceded by a dummy acquisition sequence comprising the elements of the first sequence except substantially without acquisition of data.
