Scanning pattern for iterative mr - reconstruction methods

摘要

The present invention relates to a method for the production of mr - images of an examination subject comprising the steps of:– Detection of mr - signals with a plurality of coils at the same time, wherein each coil has a separate coils characteristic, wherein in the detection of the mr - signals a raw data space (70 – 120) incompletely filled with mr - signals, wherein the raw data space in a central raw data area (71 – 121) with a coherent receiving pattern is sub-sampled, which is composed of a spatially repeating amount of raw data points, wherein the raw data space outside of the central raw data region with an incoherent receiving pattern is scanned,– Reconstruction of the mr - image with the aid of the detected mr - signals, wherein the mr - image with an iterative reconstruction method starting from an input estimate stepwise with the use of a reconstruction matrix a, it is possible to reconstruct, wherein the reconstruction matrix a information about the coils has characteristics, with which the mr - signals are detected.
