Patent ID: 7906967

Claim:
A magnetic resonance imaging apparatus comprising: a bore tube inside which an imaging space is formed to place a subject; a static field generating section which is placed outside the bore tube and generates a static field in the imaging space; a gradient field generating section which is placed between the bore tube and the static field generating section and generates a gradient field to superimpose on the static field; at least one sealing cover which is mounted to at least one side end of the static field generating section and which forms a vacuum space in a surrounding of the gradient field generating section together with the bore tube and the static field generating section, wherein the sealing cover is fixed by a fixation part thereof to the static field generating section and configured to direct an air pressure load caused by reduced air pressure in said vacuum space to be applied on the sealing cover at a part different from the fixation part and to be received by the static field generating section.
