摘要： A detector unit for arrangement in a field generating unit of a magnetic resonance device has an RF transmission/reception system for transmitting RF pulses into, or receiving magnetic resonance signals from, an examination volume of the field generation unit. The RF transmission/reception system surrounds a patient tunnel at a radial distance from a tunnel axis thereof, and is divided into two sub-systems located at a distance from each other along the direction of the tunnel axis, so as to form a substantially annular cavity or interstice therebetween.

摘要： A connecting device for a magnetic system of an imaging system includes a holding element for connection of the connecting device to a power supply connection of the magnetic system, and a connecting element for connection of the connecting device to a power supply cable for operation of the magnetic system. The connecting device also includes an oscillation damping device having a spring element. The oscillation damping device is operable to dampen oscillations of the magnetic system that act on the connecting device by way of the holding element, with respect to the connecting element.

摘要： In a computerized, automated method to determine the conductor structure of a gradient coil of a magnetic resonance device, the conductor structure is determined depending on the theoretical oscillation response of at least one metallic structure of the magnetic resonance device that is arranged adjacent to the gradient coil at the installation point, with the oscillation response of the metallic structure being determined dependent on theoretical eddy currents generated in the structure by the gradient coil.

摘要： In an arrangement of a basic field magnet and a gradient coil of a magnetic resonance apparatus, the basic field magnet includes superconducting coils that are arranged in a reservoir with liquid helium for cooling. The helium reservoir is surrounded by a further reservoir, designated as an outer vacuum chamber. A vacuum exists between the outer vacuum chamber and the helium reservoir. A cryoshield is arranged between the outer vacuum chamber and the helium reservoir. The gradient coil is arranged in the inner chamber of the basic field magnet. The cryoshield has additional structure for reinforcement that counteract vibrations of the cryoshield.
