摘要： The MRI apparatus has ring-shaped superconducting coils arranged to vertically oppose each other. The superconducting coils are installed in ring-shaped cooling containers. The cooling containers are accommodated in radiation shield plates. The radiation shield plates are accommodated in vacuum vessels. The cooling containers are connected together at at least two locations. Support members are arranged between an outer wall surface of the lower cooling container and an inner wall surface of the lower vacuum vessel to support the lower cooling container on the lower vacuum vessel. The upper cooling container is free, supported only by the connecting tubes connecting the upper and lower cooling containers.

摘要： The present invention relates to a magnetic resonance imaging apparatus, which includes a floor surface, a static magnetic field generator, two pieces of which are placed opposite each other vertically across an image pickup space, and a plurality of support legs for supporting a weight of the resonance imaging apparatus, the support legs being elastically deformed in a direction in which the weight is to be applied, and being arranged between the floor surface and a floor. Furthermore, each of the support legs has a spring constant which is set to absorb a displacement between the floor surface and the floor, while bearing the weight. This MRI apparatus has the simple structure enabling the efficient damping of the vibrations which may cause the deterioration of magnetic resonance images.

摘要： An MRI apparatus having a configuration that reduces vibration of a static magnetic field generating source is provided. A closed vessel 2 of the static magnetic field generating source is provided with a rigid structure 4 for preventing transmission of vibration generated from a gradient magnetic field generating part 21 to other members via the closed vessel 2. The rigid structure 4 uses, for example, a connecting part 4 that connects a face 25 on the imaging space side and a face 26 confronting it. The rigidity of the closed vessel is thereby increased, and therefore vibration transmitted from the gradient magnetic field generating part can be reduced. The connecting part can have a through-hole structure, and in such a case, internal space of through-hole can be used for drawing cables.
