Abstract
A magnet resonance imaging system is described having an open solenoidal magnet structure that provides a remote region of background field homogeneity for imaging that is open and accessible. The system includes spatial encoding gradient coils and a rf coil. The open magnet structure has a pair of primary solenoidal coils and a bias coil system located within the primary coil geometry. The primary and bias coils emit a total additive flux in an imaging region to generate a resulting background magnetic field profile that provides a remote region of substantial field homogeneity with open geometry for easy accessibility to a patient.
