Abstract: A radiation imaging apparatus includes an arm configured to support a radiation generating unit that generates radiation, a post configured to support the arm, a movable portion configured to support the post and to be movable on a floor, and a supporting foot portion that is rotatable with respect to the movable portion. The supporting foot portion and the arm are operable to be placed in an open state and a closed state. In a state where the supporting foot portion and the arm are closed, the supporting foot portion covers the radiation generating unit.

Abstract: A radiation generating apparatus includes a support structure that supports a radiation generating unit that generates radiation; and a base frame that supports the support structure and includes a plurality of leg portions configured to be arranged in a predetermined manner in accordance with an imaging state or storage state of the radiation generating apparatus.

Abstract: A radiation generation apparatus and a radiographic apparatus that can be easily transported and whose radiation generation unit can be installed according to the radiographing region of the object include a supporting mechanism (supporting column, arm) that supports a radiation generation unit that generates radiation, and a supporting base that supports the supporting mechanism. The supporting mechanism is removable from the supporting base together with a power source unit that supplies power to the radiation generation unit.

Abstract: A magnetic resonance imaging apparatus capable of suppressing noise caused by vibration of a gradient magnetic field coil and improving image quality includes a large number of ferromagnetic shims disposed in a large number of holes formed in a shim tray, and vibration dampers disposed in holes formed in the shim tray to reduce noise generated by vibration of a gradient magnetic field generating coil.

Abstract: A magnetic resonance imaging apparatus capable of suppressing noise caused by vibration of a gradient magnetic field coil and improving image quality is realized. A shim tray 22 is disposed between a static magnetic field generating magnet 4 and a gradient magnetic field generating coil 13. A large number of ferromagnetic shims are disposed in a large number of holes (screw holes) 24 formed in the shim tray 22. Vibration dampers 23 are disposed in holes formed in the shim tray 22 to reduce noise generated by vibration of the gradient magnetic field generating coil 13, which is propagated to the static magnetic field generating magnet through solid bodies and shakes the static magnetic field generating magnet, etc. It is hence possible to secure areas for arrangement of two means, i.e.
