Abstract:
A planar MRI system having an open magnet configuration that produces a magnetic field having a remote region of substantial magnetic field homogeneity, spatial encoding gradient coils and a rf coil, the open magnet configuration comprising:a first magnet system having a first ferromagnetic core and a first longitudinal axis with a first pair of coils around the first ferromagnetic core and spaced apart along the first longitudinal axis, the first pair of coils providing first pairs of separated current wires of the same polarity; and a second magnet system having a second ferromagnetic core and a second longitudinal axis with a second pair of coils around the second ferromagnetic core and spaced apart along the second longitudinal axis, the second pair of coils providing second pairs of separated current wires of the same polarity; wherein the first magnet system and the second magnet system are orthogonal to each other in substantially the same plane.
