摘要： A multiple examination arrangement has a number of imaging systems that are arranged at one location such that a patient lying on a movable patient support table can be examined in each of the imaging systems without changing beds. One of the imaging systems is a magnetic resonance system having an actively shielded magnet, another is a radiographic angio system, preferably offset laterally relative to the z-axis of the magnet. Selected components of the angio system have a soft-magnetic covering as shielding against the static stray field of the MR system.

摘要： In a method and X-ray device for the pickup of X-ray images in an examination of a vessel or organ that moves substantially rhythmically, particularly for the determination of deposits in a vessel, such as a coronary vessel, the X-ray pickup system of an X-ray device is slowly moved along a circular orbit at an angular velocity of less than 6° per second, during which a number of digital X-ray images are picked up, with the image pickup being triggered by the vessel motion or organ motion acquired during the system movement or by an organ motion that causes the vessel motion, and a 3D image is reconstructed on the basis of the individual images, after the image pickup has ensued.

摘要： A device for detachably securing a collimator to a radiation detector, comprising a first and second annular grooves secured to the radiation detector and the collimator respectively, a split ring having a first and second ring ends and being received in the first annular groove, and a ring diameter control system. The latter one includes a rotating hub and a first and second lever systems connected between the first and second ring ends and the rotating hub. By rotating the hub the ring ends are spread by the lever systems between a first position, where the split ring is alone positioned in the first annular groove, and a second position, where the split ring is arranged in both the first and second annular grooves, thereby attaching the collimator to the radiation detector.
