Zusammenfassung:
The homogenization of static magnetic field (B0) is necessary for MR imaging. The unwanted B0 inhomogeneity becomes more pronounced in ultra high field, and the scanner's inbuilt shim setup can not compensate the B0 fluctuation as is needed. Here we propose to use combined setup of the multi-coil approach and the scanner's shim setup to achieve higher homogeneity of B0 field. We employed custom-built multi-coil for slice-wise shimming in combination with the scanner's shim setup for global shimming. The results show improvement about 50 compare to dynamic shimming alone in the most of the slices.
