PURPOSE:To obtain a good image and mitigate the pain of a person to be checked under MRI diagnosis by optionally moving the person to be checked in the gantry opening and matching the photographing portion with the magnetic field center. CONSTITUTION:A lever 10 is fitted to the rear of the top plate 6 of a bed 8, the top plate 6 is movable only in the arrow 12 direction, a support plate 9 fitted with it is movable in the arrow 11 direction of the body axis direction, thus the top 6 is movable in two arrow directions 11 and 12. Rollers 16 provide the smooth movement of the top plate 6 in the direction perpendicular to the body axis. Seals 80 are stuck to the bed 8 and the top plate 6 to indicate the stroke center. A person to be checked 50 is mounted on the top plate 6, a high- frequency receiving coil 52 is set on the shoulder of the person to be checked 50. The photographing portion is matched with a positioning light 51 incorporated in a gantry 5, the top plate 6 is moved, the center of the coil 52 is matched, the top plate 6 is fed into the gantry by the preset quantity so that this position is matched with the magnetic field center in the gantry for photographing. |
