摘要： An RF antenna arrangement of a combined MR/PET system is disclosed. In at least one embodiment, the RF antenna arrangement includes a first part installed in the examination tunnel in a fashion fixed to the system such that it is arranged underneath the couch board when the latter is introduced, and a second part, which can be placed onto the couch board and be introduced into and withdrawn from the examination tunnel together with the couch board. In at least one embodiment, the second part is of dimensionally stable design and has a clear cross section that is adapted to the object to be examined. Consequently, the time outlay for applying the RF antenna is reduced, and the fixed position of the RF antenna enables a correction of the attenuation of gamma rays. Furthermore, a number of second parts having various diameters can be provided.

摘要： A whole-body antenna for a magnetic resonance apparatus has an antenna structure composed of a number of antenna rods extending in a rod direction between first and second ends of the antenna structure. The antenna rods are distributed around a central axis of the antenna structure, forming an examination region for an examination subject in a magnetic resonance examination. The antenna rods are coupled to each other at their first ends by a ferrule. Each of the rods is a hollow rod, and each rod is connected at its second end to ground via a hollow ring. Conductors are routed in the interior of the hollow rods, and can be routed through the hollow ring to the exterior of the antenna structure.

摘要： A patient positioning couch includes an illumination apparatus having at least one light source that is arranged in the patient positioning couch. The patient positioning couch is capable of being placed in an examination area of a medical device. Through the arrangement of the at least one light source of the illumination apparatus of the patient positioning couch, it is always ensured that the illumination does not lose its location relative to a patient or another object positioned on the patient positioning couch, even if the position of the patient positioning couch changes, e.g. if the patient positioning couch is moved into or out of the examination area. At the same time an especially space-saving illumination of the examination area can thus be achieved.

摘要： An antenna unit for a PET/MRI scanner is disclosed, including a supporting tube in which at least one antenna for MR signals is arranged. In at least one embodiment, the supporting tube has at least one permeable section and one impermeable section, the permeable section of which has a greater permeability to PET quanta than the impermeable section. The antenna unit further includes a screen for radio-frequency signals which is arranged outside of the supporting tube and surrounds the latter. In at least one embodiment, an intermediate layer is arranged between the supporting tube and the screen and, in the region of the permeable section of the supporting tube, is composed of, at least in part, a material which has a permeability to PET quanta comparable to the permeable section.
