Abstract:
A magnetic resonance imaging system for generating an image of a patient, comprising:a lower body having a flat upper surface, said lower body having a first magnetic pole provided therein, said lower body rests on a floor surface, said patient rests on said lower body;an upper body having a lower surface disposed in opposed relation to said upper surface of said lower body, said upper body having a second magnetic pole provided therein; anda pair of support posts provided outside said lower body and connected to said lower body, said pair of support posts support said upper body,wherein said upper body have at least a front portion of a lower peripheral edge thereof as being chamfered,wherein said upper body being positioned relative to said lower body in a manner such that access to said patient resting on said lower body is not obstructed by said upper body,wherein said first and second magnetic poles produce a magnetic field which is used to generate said image,wherein said lower body is provided with an outer peripheral surface, and a bed connecting portion formed to project before said outer peripheral surface,wherein said upper body have at least a front side formed in a circular arc shape, an outer peripheral surface formed vertically to said lower surface and concentric with a circular arc of said lower surface to have a diameter larger than that of said circular arc, and said front portion being formed as an oblique surface between said lower surface and said outer peripheral surface,wherein a space is formed between said lower body and said upper body,wherein said pair of support posts is connected to each side surface of said lower and upper bodies and disposed symmetrically in right and left directions with respect to said lower and upper bodies, andwherein said pair of support posts have a recess formed at said space side of each of said pair of support posts in an area of said space, and each front surface of said pair of support posts formed substantially vertical to said side surface, each front surface of said pair of support posts being connected to said outer peripheral surface of said lower body, and said front surface of said lower body projecting at a connecting position thereof.
