Claim 10:
11. 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 a first magnet and a second magnet that confine the imaging volume in two spatial directions oriented at an angle of 180° to one another, the first magnet and the second magnet being arranged asymmetrically with respect to the imaging volume and being arranged to provide an access to the imaging volume along at least two perpendicular spatial directions, wherein:
a smallest distance between the first magnet and a center of the imaging volume is unequal to a smallest distance between the second magnet and the center of the imaging volume,
the first 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 first magnet varies in the direction of access to the imaging volume, and
the direction of access to the imaging volume along each of the at least two perpendicular spatial directions is angled with respect to a main direction of magnetic field lines within the imaging volume.
