Method for operating a magnetic resonance tomography apparatus wherein the location coding is adapted to a positional change of the examination subject

摘要

In a method for the operation of a magnetic resonance tomography apparatus having a gradient system and a radio-frequency system that, among other things, serve for location coding, a region to be imaged in an examination subject is placed in an imaging volume of the apparatus. Image datasets of at least parts of the region to be imaged are generated in a time sequence. A positional change of at least a part of the region to be imaged with respect to the imaging volume is determined by a comparison of at least a first image dataset to a second image dataset that have been generated in chronological succession. A location coding is adapted corresponding to the identified positional change for at least one image dataset that is generated following the compared image datasets in time.
