Avoidance of artifacts as part of an acquisition of measurement data using magnetic resonance technology

摘要

In a method according to the invention for avoiding artifacts in the acquisition of MR data of an examination object, a first and a second subsampled data record are recorded, wherein the measurement data of the first data set and the measurement data of the second data set are selected such that artifacts in the first data record a have different phase than in the second data record and wherein the measured data recorded in the first data record and in the second data record also together correspond to a Nyquist subsampled data record. The recorded subsampled data sets are supplemented by means of a supplementary kernel of a parallel acquisition method to supplemented data records on the basis of a combined, artifact-free data set is created. By recording the measurement data recorded in the first data record and in the second data record in such a way that a data record subsampled according to Nyquist is taken together, the measurement time is reduced both compared to a conventional PAT averaging method and to a recording without the use of a parallel acquisition method ,
