Claim 3:
4. 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,
wherein the at least one magnet is configured as a gradient magnet comprising a set of gradient coils configured to generate a magnetic gradient field in the imaging volume, and
wherein 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.
