An apparatus for magnetic resonance imaging is described having a casing
with an inner bore which in some embodiments is substantially
frustoconical shape for receiving a subject. The apparatus contains
devices disposed in the casing to create a uniform field within an inner
bore. The apparatus employs dual access since the inner bore has a first
and second end at the outer edge of the casing for which the part of the
subject's body would travel so as to be imaged. Further, in some
embodiments, the apparatus provides one or more recesses for inserting at
least one gradient coils into position about an inner bore. The MRI
system induces resonance in selected dipoles in an examination region
created along an inner bore of a casing housing in a magnetic resonance
imaging system such that the selected dipoles generate magnetic resonance
signals to create an image representation of the part of the subject's
body.
