摘要

We present a highly scalable and versatile family of dipole magnet designs suitable for high-resolution magnetic resonance imaging (MRI), constructed entirely from cylindrical permanent magnet rods of two distinct radii. The multiplicity, N, of the main set of rods (which dominate the generated field) can vary from 10 to 26. For each such N, we present several designs that produce magnetic fields ...
