Abstract

In a method and apparatus to detect incorrect MR data in k-space representing MR signals acquired from an examination subject with at least two acquisition coils, MR data are acquired to generate at least one raw data set with each of the at least two acquisition coils and a check is made, for at least one k-space point, as to whether the MR data acquired for this k-space point should be replaced or not. In the event that the check yields that the MR data acquired for the at least one k-space point should be replaced, the MR data are replaced with reconstructed MR data that are based on at least two of the acquired raw data sets.
