A process for the correction of distortions by means of a magnetic resonance apparatus, in the recorded image data sets, as well as a computer program, image processing unit and magnetic resonance apparatus for carrying out the method

摘要

The method according to the invention is calculated local displacement of image elements in a charged image data set with the use of known exposure parameters, with a magnetic resonance apparatus has been received. In this case, for the calculation of the local shifting the known exposure parameters, and known local deviations of a bias magnetic field of the magnetic resonance device in a measuring volume of the magnetic resonance apparatus used. On the basis of the calculated displacements and of the charged image data set is created, a corrected image data set. This is finally korigierte image data set is displayed and / or stored.In addition, a computer program product, an image processing unit and a magnetic resonance apparatus for carrying out the method claimed.
