摘要： A radio-frequency antenna for a magnetic resonance system has a number of antenna rods and two end rings. The antenna rods are regularly arranged around an antenna axis and are connected at their respective rod ends to the end rings. When the antenna rods proceed essentially parallel to the antenna axis, they have a rod spacing in their middle region from the antenna axis that is smaller than a end ring spacing that at least one of the end rings exhibits from the antenna axis. When the antenna rods form an angle of inclination with the antenna axis, they have a rod spacing from the antenna axis at their end lying closer to the antenna axis that is smaller than an end ring spacing exhibited by the end ring that is connected to that rod end. In both version, rod spacing lies between 25 and 35 cm and is between 5 and 15 mm smaller than the end ring spacing.

摘要： A radio-frequency shield for a diagnostic magnetic resonance apparatus has a hollow-cylindrical carrier composed of a dielectric, a first electrically conductive coating arranged at an inside of the carrier and provided with axially aligned separating slots, and A second electrically conductive coating arranged at an outside of the carrier and provided with axially aligned separating slots. The separating slots in the first and second coatings, respectively, are offset relative to one another in a circumferential direction. The first coating has slotted end regions at the ends of the carrier and at least one slofted middle region between the end regions. The separating slots arranged in the end regions are transverse slots that are arranged at axially inwardly disposed ends of the separating slots.

摘要： 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.
