Method for correction of distortion in image data records recorded by means of a magnetic resonance scanner, as well as a computer program, image processing unit and magnetic resonance scanner for carrying out the method
A method is disclosed which calculates local shifts of image elements in a loaded image data record which has been recorded by a magnetic resonance scanner using known recording parameters. In at least one embodiment, the known recording parameters and known local discrepancies of a basic magnetic field of the magnetic resonance scanner in a measurement volume of the magnetic resonance scanner are used to calculate the local shifts. A corrected image data record is created on the basis of the calculated shifts and the loaded image data record. This corrected image data record is finally displayed and/or stored. Furthermore, a computer program, an image processing unit and a magnetic resonance scanner for carrying out the method are disclosed.
