Abstract: A dividing wall made from at least one first wall material for delimitation of a patient positioning region from an antenna structure of a magnetic resonance tomography apparatus has at least one region at which a specific sub-structure of the antenna structure is located on the side of the dividing wall facing away from the patient positioning region, at which the dividing wall has a wall part made from a second wall material with a dielectric constant that is lower than the dielectric constant of the first wall material.

Abstract: A device to install and remove a structural component in and from a medical large device has a guide system that simplifies the difficult handling of the structural component due to the size or the weight of the structural component. The guide system has a first guide rail that can be positioned on a height-adjustable patient bed of the large device, and a guide groove which is arranged on the structural component. Additionally, another second guide rail can be attached to the medical large device, which forms an extension of the first guide rail when the patient bed is correspondingly positioned. With this device the structural component can be easily raised and lowered with the aid of the height-adjustable patient bed, and can easily be slid into and out of the large device when the first and second rails are at the same height.

Abstract: Magnetic resonance scanner has a radio-frequency system with transmission/reception antennas, and possibly a radio-frequency shield as well, and guides for a movable patient bed arranged in a basic field system and in a gradient system, with the electrical components of the radio-frequency system being embedded in a cylindrical, rigid carrier tube that penetrates the basic field system and the gradient system in the axial direction and which simultaneously serves as a carrier for the guides for the patient bed. The carrier tube is introducible as structural unit into the basic field and gradient system.
