Device having a C-arm and X-ray imager

An x-ray imager comprising:

• a C-arm comprising a main body having a cross-sectional profile with a double H-shape, an outer wall, an inner wall, and two side walls of the main body providing a rectangular cavity;
• running wires arranged on the main body of the C-arm;
• running wire carriers, wherein the running wires are arranged in or on the running wire carriers;
• running rollers, on which the C-arm is movably mounted, configured to roll on the running wires;
• an x-ray source arranged at a first end of the C-arm;
• and
• an x-ray detector arranged at a second, opposite end of the C-arm,
• wherein the outer wall and the inner wall extend beyond the rectangular cavity and forming on each side of the main body two projecting legs and each leg forming with a side wall of the two side walls an edge running in a longitudinal direction of the main body, and
• wherein the running wire carriers are arranged along the edges formed by each leg and the side walls and are positioned such that at least 50 percent of mounting forces acting on the running wires due to the running rollers is introduced into the side walls of the main body.
