From: Common artefacts encountered on images acquired with combined compressed sensing and SENSE
Type of artefact | Strategy for artefact correction |
---|---|
Type-A streaks | The reconstruction voxel must be at least the same size as the acquisition voxel |
Type-B streaks | Repetition of sequence |
Type-C streaks | a rest slab has to be placed directly adjacent to the object scanned without any gap and an oversampling rate of 10% has to be added |
Wax-layer artefact | Repetition of sequence |
Starry-sky artefact | Repetition of sequence |
