Direct Signal Control can be used for improving signal uniformity for TSE based 3D-FLAIR imaging at 7T by using dynamic RF shimming through the echo train. The need to calibrate and optimize on a subject-specific basis can be a workflow issue. In this work we evaluate generic solutions that are calculated in advance, in comparison with individual subject-specific optimizations.
