Abstract:
A magnet for magnetic resonance imaging apparatus comprising:(1) A ferromagnetic frame including:(a) a pair of opposed ferromagnetic pole supports spaced apart from one another;(b) a pair of ferromagnetic poles connected to said pole supports, said poles projecting from said pole supports toward one another along a polar axis, said poles having distal ends spaced apart from said pole supports, said distal ends confronting one another and being spaced apart from one another by a gap distance so as to define a patient-receiving gap therebetween;(c) one or more connecting elements extending between said pole supports, said connecting elements being remote from said poles in a direction or direction transverse to said polar axis; and(2) a source of magnetic flux adapted to direct flux through said frame so that said flux passes between said distal ends of said poles through said gap and returns through said pole supports and said connecting elements,said magnet defining a working space within said ferromagnetic frame alongside of said poles sufficient to accommodate one or more physicians, whereby a physician in said working space can have access to a patient disposed in said gap.
