Abstract
Data of an examination object comprises a volume-data record and a plurality of two-dimensional projection images. The volume-data record includes voxels where each voxel is assigned to a location in three-dimensional space. Each projection image includes pixels where each pixel is assigned to a location in a two-dimensional-projection plane and has a value. Each pixel is assigned a projection volume, this being specified in that it is mapped by the radioscopy onto the pixel to which it is assigned. A sub-volume of the volume-data record is selected. The projection images are registered in relation to the volume-data record. A functional parameter of the examination object is specified for the pixels of the projection images, depending on their values. For each pixel, when specifying the functional parameter, consideration is given to the locations and/or the number of those voxels which are positioned both within the sub-volume and within the projection volume.
