Abstract
A method of correcting distortions in magnetic resonance (MR) data is described. The method comprises providing distorted MR data of an object of interest and distortion parameters for one or more generic objects, determining transformation parameters correlating the object of interest and one or more of the generic objects, and processing the distorted MR data taking into account the distortion parameters and the transformation parameters to obtain corrected MR data.

A method of correcting distortions in magnetic resonance (MR) data, comprising:
- a) providing distorted MR data of an object of interest and distortion parameters for one or more generic objects;
- b) determining transformation parameters correlating the object of interest and one or more of the generic objects;
- and
- c) processing the distorted MR data taking into account the distortion parameters and the transformation parameters to obtain corrected MR data.
An apparatus for correcting distortions in magnetic resonance (MR) data, comprising:
- a common database or separate databases for at least temporarily storing distorted MR data of a object of interest and distortion parameters for one or more generic objects;
- a unit for generating transformation parameters correlating the object of interest and one or more of the generic objects;
- and
- a unit for processing the distorted MR data taking into account the distortion parameters and the transformation parameters to obtain corrected MR data.
