Abstract: In a magnetic resonance imaging apparatus and a method for shimming such an apparatus, at each of mirror-symmetrical assemblies respectively disposed at opposite faces of a static magnetic field generator, that each include a shimming ring, an additional shimming ring is provided that is adjustable in position relative to the other shimming ring to shim the static magnetic field. Additionally or alternatively, at each face of the static magnetic field generator, a permanently magnetic arrangement is provided that is divided into a number of permanently magnetic columns respectively having different energy levels. Additionally or alternatively, magnetic bolts, such as magnetically conducting bolts or permanently magnetic bolts can be symmetrically inserted into either of the mirror-symmetric assemblies, or the permanently magnetic columns, for additionally shimming adjustment.

Abstract: An air pressure fixed coil for magnetic resonance imaging has a surface on which an air pressure fixing device is arranged. The air pressure fixing device is in communication with a control switch, that is operable to actuate the air pressure fixing device to generate a negative pressure or to restore a normal air pressure, so that the air pressure fixing device is suctioned and fixed onto an object, or is released from the object. Since the coil is fixed in place by using air pressure, the coil can be fixed onto a patient bed without arranging any fixing structure on the patient bed, and therefore the coil can be positioned and fixed at any place on the patient bed for carrying out a scanning operation according to needs. At the same time, since there is no need to pre-arrange any fixing structure on the patient bed, such as slots, holes etc., the structural strength of the patient bed will not be affected, and the appearance of the patient bed can be kept simple, clean and neat.

Additionally, or alternatively, the circumferences of the magnetic field generating sources (5, 51) are arranged with adjusting bars (71, 81) which can move perpendicular to the pole plates. As an advantage of the present invention, the magnetic field can be shimmed conveniently quickly, and accurately to improve the imaging quality.
