Synopsis

Keywords: Shims, High-Field MRIWe present a new method for passive shimming based on 3D printed ferromagnetic inks that are fully compatible with the scanner RF coils. We show simulated B0 shim performance for designs that are optimized to shim the human brain for both a subject-specific passive shim insert and a robust general insert.
