Abstract

In an X-ray imaging system with a C-arm which exhibits mechanical instability and changes the radiation geometry, the image reconstruction ensues with a calculation of the coordinates of the individual voxels being forgone. A voxel-driven back projection ensues without the calculation of positional coordinates and physical focus position and detector position.
