Abstract:
Magnetic resonance scanning apparatus comprising:a magnet comprising a pair of opposed ferromagnetic pole surfaces disposed facing each other and defining therebetween a patient-receiving gap for receiving a patient to be studied by magnetic resonance, a magnetic flux return circuit for magnetic flux which passes from one pole surface to the other through the patient-receiving gap, said magnet generating magnetic flux flowing from one to the other of said pole surfaces through the patient-receiving gap; anda room having a floor, wherein said pole surfaces are within said room and above said floor, said magnetic flux return circuit extends to the exterior of said room, said pole surfaces are spaced apart from one another in a horizontal direction above said floor, and magnetic resonance studies are carried out with said magnet on a patient positioned between said pair of opposed ferromagnetic pole surfaces, said room having dimensions sufficient to accommodate one or more medical personnel within said room, supported on said floor.
