Abstract
A magnetic resonance imaging apparatus includes a main magnet having a frame (19) with two magnetic elements (1) arranged thereon. The magnetic elements (1) have substantially parallel faces (3) that face each other so as to define a gap (5) between the magnetic elements. The magnetic elements (1) have magnetic poles of opposite polarities for generating a static magnetic field in the gap (5). A patient support (45) is provided for supporting a patient (47) so that a part of the patient that is to be examined is located in the gap (5). In order to improve the accessibility of the patient (47) without increasing the width of the gap (5), a supporting member (37) is arranged so as to support the frame (19) in such a position that the normals (41) to the planes of the substantially parallel faces (3) of the magnetic elements (1) extend in a direction that encloses an angle between 30.degree. and 60.degree. with the vertical direction.
