A mechanism for transporting a patient to a magnetic resonance unit. A coil seat is mounted on the upper surface of a lower bed and the lower bed is mounted for movement relative to a magnet. An upper bed is mounted for movement on the lower bed. In the positioning stage, the coil is located outside of the magnet and the upper bed carrying a patient is moved relative to the lower bed to position the patient in registry with the coil, such that a desired anatomical area is brought into the imaging area of the coil. This is followed by pushing the upper and lower beds as a unit into the bore of the magnet. As various coils can be positioned on the lower bed at a common positioning location, it is possible to employ a common electric connection to eliminate the need for separately attachable cables.
A magnetic resonance unit, comprising a supporting structure, a magnet mounted on the supporting structure and having a central bore, a lower bed, a coil assembly mounted in fixed relation to the upper surface of said lower bed, means for mounting said lower bed for movement relative to said supporting structure from a first location where the coil assembly is outside of said bore to a second location where the coil assembly is located within the bore of a magnet, an upper bed to support a patient, means for mounting the upper bed for movement relative to the upper surface of the lower bed whereby the upper bed can be moved relative to the lower bed when the lower bed is in the first location to position the patient in registry with the coil assembly, and means for moving the lower bed with the associated coil assembly along with the upper bed and the patient supported thereon in unison to the second location in the bore of the magnet.
A method of transporting a patient to a magnetic resonance unit, comprising the steps of supporting a patient on an upper movable bed, moving the upper bed to a lower bed relative to a coil mounted on said lower bed to position the patient in registry with the coil, and moving the upper bed and the lower bed in conjunction to position the coil and the patient in the bore of a magnet of a magnetic resonance unit.
