Abstract
A magnetic resonance apparatus for examinations having a local gradient coil unit (insert gradient coils) has a driven support mechanism (patient bed) with which the examination subject can be introduced into the examination space of the magnetic resonance apparatus, and a coupling device with which a gradient coil unit can be coupled to the patient bed and can be moved into the examination space by the driven patient bed. The gradient coil unit is positioned in the examination space by the patient bed and does not required its own drive.
Claims8
A magnetic resonance apparatus comprising:
- a magnetic resonance scanner having an interior examination space;
- a patient bed mechanism, adapted to receive an examination subject thereon, which is movable into and out of said examination space;
- a gradient coil unit which is movable into and out of said examination space;
- and
- a coupling unit for coupling said gradient coil unit to said patient bed mechanism for moving said gradient coil unit relative to said examination space with said patient bed mechanism, said coupling device automatically firmly joining said gradient coil unit to said patient bed mechanism when said patient bed mechanism moves toward and contacts said gradient coil unit in a movement direction, and releases said gradient coil unit from said patient bed mechanism when said patient bed mechanism again moves in said movement direction.
