Abstract:
In a method and apparatus for producing respiration-corrected MR images of an examination volume containing the heart of a patient during respiratory movement of MR signals are recorded continuously during multiple cardiac cycles, each cardiac cycle having multiple time segments. One 2D navigator image data record per cardiac cycle is recorded during a time segment of that cardiac cycle, with k-space being filled along a Cartesian trajectory such that a spatial resolution is achieved in two spatial directions of the examination volume. Also, multiple 3D image data records are recorded in the other time segments of that cardiac cycle, with Cartesian filling of raw data space such that a spatial resolution is achieved in all three spatial directions of the examination volume. The respiratory movement is then determined from these navigator data records. The determined respiratory movement is corrected in the recorded MR signals.
