要旨:
To make use of the full capacity of fMRI applications in ultra-high field strengths, an excellent B0 shimming is inevitable. Usually these applications suffer from major distortions and signal drop-outs in the frontal cortex area. This work presents a modified approach of B0 shimming, which enables the restoration of signal in the frontal cortex and therefore renders fMRI applications in the frontal cortex possible.
