Field-based spatial self-registration of multi-coil hardware for B0 field control

Year: 2024

Type: conference-paper

Abstract: Motivation: Successful multi-coil B0 field control relies on reproducible hardware placement. Goal(s): Our goal was to detect hardware misplacements from MC-generated field patterns alone (i.e. without field probes) to allow spatial transformations for correction. Approach: We co-registered unique field maps before and after hardware displacements to derive the underlying translation and rotation parameters. Results: In simulation and preliminary scanner validation, hardware misplacements were detected with sub-millimeter/sub-degree precision. Impact: Field-based spatial self-registration for multi-coil field inserts is expected to allow optimal B0 field control even with differences in hardware placement, thus preserving the best shim performance.
