The image capturing apparatus according to claim 10, wherein the image capturing apparatus comprises at least one shielding element arranged between the screen and one of the plurality of cameras so that the at least one of the plurality of cameras is entirely arranged behind the shielding element with respect to the screen, wherein the at least one shielding element is configured to absorb X-ray energy of 200 keV or more, wherein at least one other of the plurality of cameras is arranged behind the at least one shielding element. 12. The image capturing apparatus according to claim 1, wherein the image capturing apparatus comprises a plurality of radiation-protection glasses arranged between the plurality of mirrors and the plurality of cameras. 13. The image capturing apparatus according to claim 1, wherein the plurality of cameras captures the respective portion of the screen via exactly one of the multitude of mirrors, respectively. 14. The image capturing apparatus according to claim 1, wherein a number of the mirrors is equal to a number of the cameras. 15. The image capturing apparatus according to claim 1, wherein the screen is a scintillator. 16. The image capturing apparatus according to claim 1, wherein the plurality of mirrors and a plurality of cameras are arranged such that the plurality of cameras captures at least partially differing portions of the screen. 17. The image capturing apparatus according to claim 1, wherein the plurality of camera/optic combinations comprises a Scheimpflug arrangement;wherein the plurality of mirrors and the plurality of cameras are arranged such that the plurality of cameras each captures the respective portion of the screen under Scheimpflug conditions via the respective mirrors. 18. The image capturing apparatus according to claim 1, wherein imaging the screen takes place in parallel to a normal of the screen. 19. The image capturing apparatus according to claim 1, wherein imaging the screen takes place obliquely to a normal of the screen. 20. The image capturing apparatus according to claim 1, wherein the screen comprises an area, and wherein a predetermined total resolution is provided for the optical capturing of the screen, wherein each of the plurality of cameras is configured to capture the respective portion of the screen, which comprises a partial area of the screen area, with an individual resolution that is higher than the total resolution. 21. The image capturing apparatus according to claim 20, wherein the image capturing apparatus comprises an image processor for processing individual images of the plurality of cameras, wherein the image processor is configured to melt the individual images of the plurality of cameras into a total image that represents the optical capturing of the screen with the predetermined total resolution. 22. The image capturing apparatus according to claim 21, wherein the image processor is configured to compute each pixel of the total image by weighted summing up of locally corresponding pixels of the digital individual images. 23. A method for capturing a screen, comprising:capturing the screen with a plurality of cameras via a plurality of mirrors;wherein the plurality of mirrors and the plurality of cameras are arranged such that the plurality of cameras each capture a portion of the screen via a respective one of the plurality of mirrors, respectively, andwherein the plurality of cameras is arranged obliquely with respect to the screen;wherein the multitude of cameras is arranged with respect to the screen such that angles between capturing directions of the plurality of cameras and a screen plane are between 5° and 85°;wherein the screen is a scintillator screen,wherein the capturing directions are perpendicular to objective planes of the plurality of cameras. 24.
