| titleOfInvention | Medical x-ray device and method for an energy calibration |
| abstract | The invention relates to a medical x-ray device (1) having a first x-ray source (2) and a first counting x-ray detector (4). According to the invention, a. the first x-ray source (2) emits a beam bundle (7) with x-ray photons (8), b. the first counting x-ray detector (4) has a detection surface (11), wherein an angle (14) between the surface normal (13) of the detection surface (11) and a central beam (12) of the beam bundle (7) can be adjusted such that the central beam (12) of the beam bundle (7) does not run normal to the detection surface (11) in a calibration operation, and c. a calibration target (6) can be positioned such that calibration photons (9) are triggered in the calibration target (6) by means of the x-ray photons (8), and the calibration photons (9) are incident on at least one sub-region (15) of the detection surface (11). The sub-region (15) of the detection surface (11) is substantially shielded from x-ray photons (8). |
