Claim 0:
1. A magnetic resonance imaging (MRI) device comprising:
a field generator configured to provide a magnetic field in an imaging volume of the MRI device, the field generator including at least one magnet that confines the imaging volume in at least one spatial direction, wherein:
the at least one magnet is curved such that a perpendicular distance between a line oriented along a direction of access to the imaging volume and a surface directed towards the imaging volume of the at least one magnet varies in the direction of access to the imaging volume,
the at least one magnet is configured to enclose at least a part of the imaging volume along at least a part of the line oriented along the direction of access to the imaging volume, the direction of access to the imaging volume being oriented in parallel to a main direction of magnetic field lines within the imaging volume, and
the at least one magnet is arranged such that a minimum perpendicular distance between the line oriented along the direction of access to the imaging volume and the surface directed towards the imaging volume of the at least one magnet is located at a center of the imaging volume.
