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.
