1. A magnetic resonance imaging device, comprising:
a field generation unit configured to provide a magnetic field in an imaging volume of the magnetic resonance imaging device, and comprising at least one magnet,
wherein a surface of the field generation unit directed towards the imaging volume of the at least one magnet comprises a concave shape, and a direction of access to the imaging volume is oriented essentially perpendicular to a main direction of magnetic field lines in the imaging volume, and
wherein the at least one magnet is configured to accommodate a patient in a sitting position on the surface directed towards the imaging volume, and the at least one magnet comprises at least one recess configured to accommodate a leg of the patient positioned in the sitting position.
