Magnetic susceptibility variation leads to B0 field inhomogeneity and causes artifacts including line broadening, signal dropout and image distortions. We present a novel method to choose the magnetic susceptibility and dimensions of shim elements in the design of a cylindrical shim insert and validate our technique using simulation.
