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.

A magnetic resonance imaging device is also provided. The electromagnet device comprises a first coil (31) through which a first circular current (J1) circulates forward, a second coil (32) through which a second circular current (J2) circulates reversely, and a coil group (30) through which a plurality of circular currents (J3-J6) circulate alternately forward and reversely. The first coil (30), the second coil (32) and the coil group (30) are arranged in this order to increase the angle of elevation θ (θ1

摘要： A vehicle surrounding-area monitoring apparatus that, when recognizing an obstacle, allows for easy determination of the positional relationship between the obstacle and scenery included in a video image of the area surrounding the vehicle, generates a narrow view-field region that is a part of the video image as a notable video image, and if an obstacle region that is a region of the recognized obstacle in the video image is located outside of the narrow view-field region and if the obstacle region is contained in an image region that is partially overlapping with the narrow view-field region and is a part of the video image, generates the image region as a notable obstacle image so as to generate a surrounding-area monitoring display image comprised of the notable video image and the notable obstacle image.
