Abstract
Lipid suppression in magnetic resonance imaging ('MRI') is provided on a slice-by-slice basis using tailored local field control that is configured for lipid control for each slice in a planned slice prescription. Only those lipid voxels that fall within the bandwidth of the concurrent RF excitation pulse are targeted. Switched Boffset fields are used to improve lipid suppression pulse performance by pushing water and lipids apart in the frequency domain. Multi-coil Bshim arrays with rapidly switchable output currents that can be turned on during the lipid suppression pulse may be used. A convex optimization may be used to jointly solve for the shim currents and the lipid suppression pulse center frequency and bandwidth to optimize lipid suppression while minimizing water signal loss.
