Automatic determination of a correction factor for generating magnetic resonance images, magnetic resonance systems and computer program products

摘要

The invention relates to a method for automatically determining a correction factor for generating magnetic resonance images, the method comprising: outputting a first reading gradient along a readout dimension, reading out a first MR signal of an examination subject while outputting the first reading gradient, presetting a second reading gradient with a theoretically the same gradient moment as the first read gradient, - a time profile being specified for the second read gradient that is different from a time profile of the first read gradient, - output of the second read gradient along the readout dimension, - readout of a second MR signal of the Examination subject during the output of the second reading gradient, determination of a first extent of an image of the examination subject on the basis of the first MR signal, determination of a second extent of an image of the examination subject on the basis of the second MR-Si gnals- Determination of a correction factor on the basis of a ratio between the first and the second expansion.
