Lessons Learned in Applying Efficient B1 Shimming Techniques at UHF

Daniel K. Stough¹, Tamer Ibrahim

The improvement of MR coil signal at UHF requires a gamut of solutions to overcome hindrances. B₁ shimming provides a straight forward mechanism for RF optimization, but can be tricky to implement in practice. The learning experiences encountered in the implementation of shimming for multi-transmit 7T coils will discussed as well as background material for real-time computation, as learned in the development of a shimming optimization software program.
