Description

Technical Field

[0001] The utility model relates to the technical field of medical imaging, in particular to a magnetic resonance device.

[0002] Regardless of the grammatical gender of a particular term, persons with both masculine and feminine identities are included. Background Art

[0003] In a magnetic resonance examination, magnetic resonance data and / or magnetic resonance signals are detected by means of local radio frequency coils. These local radio frequency coils are preferably arranged around the area of ​​the patient to be examined. In this case, the local radio frequency coils can differ in the examination area and / or be adapted to the area of ​​the patient to be examined, for example in the form of a head radio frequency coil or a knee radio frequency coil or the like.

[0004] For data transmission of detected magnetic resonance signals and / or for controlling the local radio frequency coil, the examination bed preferably has so-called plug contacts, into which the plug elements of the local radio frequency coil are inserted for data exchange and / or data transmission. These plug contacts are connected to the evaluation unit and / or the control unit for data exchange. For this purpose, the magnetic resonance device has a coil cable. In this case, the coil cable must have a certain length to compensate for the movement of the examination bed, especially in the patient accommodation area.

[0005] Until now, it has been known that coil cables for compensating for the movement of the examination table are stored inside the examination table. However, in order to avoid interference, a large number of surface wave traps need to be integrated into the coil cables. However, such a solution is particularly cost-intensive.

[0006] Another solution for storing the coil cable is to lead the coil cable out through the back opening of the patient accommodation area and to provide a cable storage device at the back side of the magnetic resonance device to accommodate the excess coil cable. However, this solution requires a larger space requirement at the back side of the magnetic resonance device.

[0007] Furthermore, magnetic resonance systems are known which additionally comprise a local transmission coil, for example magnetic resonance systems with a very high basic field strength, for example a basic field strength of 7 T. Such transmission coils are connected to relatively thick coil cables which have only low bending properties, so that a high space requirement must be applied to maintain such coil cables.
