摘要：
A magnetic resonance apparatus which may include: a body portion having a cavity with a first and second ends and at least one opening situated at one of the first and second ends. The cavity may define a longitudinal axis (LA) extending between the first and second ends. At least one main magnet may generate a main magnetic field having a substantially homogenous magnetic field within the cavity. A center shim (CS) which may be formed from a ring having opposed edges and which may extend along a length of the longitudinal axis of the cavity. One or more discrete shims (DSs) may be situated between the CS and at least one of the first and second ends.
