Abstract:
1. An open magnetic resonance imaging (MRI) device, comprising: a main coil configured to generate a magnetic field to image a volume, wherein the main coil comprises a first axis, a first radius, and a first axial distance from the volume; a plurality of shaping coils comprising second axes, second radii, and second axial distances from the volume, wherein the second radii are smaller than the first radius of the main coil, and wherein the second axial distances are greater than or equal to the first axial distance of the main coil to shape the magnetic field in the volume; a substantially cylindrical support comprising a third axis and a third radius, wherein the first, second, and third axes are generally aligned with one another, wherein the substantially cylindrical support is disposed radially between and completely separating the main coil and from the plurality of shaping coils; and a pressure vessel disposed about the main coil, the plurality of shaping coils, and the substantially cylindrical support.
