Abstract: 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.

Abstract: A method and device are used for automatized dose planning in stereotactic radiosurgery. The method comprises the steps of: inputting into a computer location data on the target volume to be irradiated; positioning in the dose plan a number of shots having a preliminary weight, in certain preliminary positions in the target volume; and by an iterative minimizing method, minimizing the dose plan with respect to shot positions and shot weights.
