摘要： A method for monitoring a radiation dose applied to a patient being exposed or having been exposed to radiation from a medical imaging system, the medical imaging system comprising an X-ray source, the X-ray source describing a trajectory in a coordinate system of reference of the medical imaging system having an origin, the method comprising determining the current coordinates, in the coordinate system of reference of the medical imaging system, of a current region being exposed or having been exposed to radiation from the X-ray source, of an envelope of a patient model, in relation to a current position of the X-ray source, determining, from the current coordinates, a current coordinate system of reference having as origin the current position of the X-ray source, the current coordinate system of reference being centered on the current region, and displaying a representation of the current region centered on the current coordinate system of reference.

摘要： The embodiments relate to a method for adapting at least one radiation parameter of a beam source in an x-ray device, wherein the beam source is activated according to the radiation parameter for providing x-radiation, wherein, as long as the filter element is not being moved, the radiation parameter is specified based on image data acquired in a transillumination region by the beam detector, wherein at least one interim image is recorded at least partially within a movement interval during which the filter element is moved, after which the radiation parameter is specified independently of the image data of the interim image or after which exclusively image data of the interim image that are acquired in an overlapping region of the beam detector that lies within the transillumination region during the entire recording interval are taken into account in the determination of the radiation parameter.
