X-ray system with modular two-layer detector

An X-ray imaging system, comprising:

• a detection system that comprises:
• a first detector configured to detect X-ray radiation of the X-ray imaging system impinging onto a first detection area of the first detector;
• a second detector configured to detect X-ray radiation of the X-ray imaging system impinging onto a second detection area of the second detector;
• wherein the detection system is configured to adjust a position of at least one of the first detector and the second detector with respect to the other of the first detector and the second detector;
• wherein the detection system is configured to position the first detection area of the first detector and the second detection area of the second detector at least partially one behind the other with respect to a direction of the X-ray radiation impinging onto the first detection area and the second detection area;
• wherein a size of the second detection area of the second detector differs from a size of the first detection area of the first detector;
• at least one processor configured to reconstruct an X-ray image based on X-ray radiation that is detected by the first detector and the second detector;
• wherein the reconstructed X-ray image comprises a first region and a second region, wherein the first region is reconstructed based on X-ray radiation that is detected by both the first detector and the second detector, wherein the second region is reconstructed based on X-ray radiation that is detected by one of the first detector and the second detector, and wherein at least one image characteristic of the X-ray image is better in the first region than in the second region;
• and
• an X-ray source.

A computer-implemented method for imaging a subject using an X-ray imaging system, comprising:
