An apparatus for detecting an image, comprising: an image source; a mirror arrangement for deflecting radiation which may be generated by the image source; and a detector for receiving radiation deflected by the mirror arrangement, the mirror arrangement comprising: a first mirror arranged to reflect the radiation generated by the image source; a second mirror arranged to reflect radiation reflected by the first mirror, the first mirror and the second mirror being spaced apart from one another and being parallel to one another or forming an angle of less than 90° between them, a third mirror and a fourth mirror, the first mirror being arranged to reflect only such radiation to a sensitive detector region which comes from a first subregion of the image source, the third mirror being arranged to reflect only such radiation to a sensitive detector region which comes from a second subregion of the image source, the first subregion differing from the second subregion, and the fourth mirror being arranged to reflect radiation reflected by the third mirror, the third mirror being arranged on a rear side of the second mirror, characterized in that an X-ray absorber material is arranged between the second mirror and the third mirror, the second mirror and the third mirror are configured on different sides of a support material absorbing X-rays. an image source; a mirror arrangement for deflecting radiation which may be generated by the image source; and a detector for receiving radiation deflected by the mirror arrangement, the mirror arrangement comprising: a first mirror arranged to reflect the radiation generated by the image source; a second mirror arranged to reflect radiation reflected by the first mirror, the first mirror and the second mirror being spaced apart from one another and being parallel to one another or forming an angle of less than 90° between them, a third mirror and a fourth mirror, the first mirror being arranged to reflect only such radiation to a sensitive detector region which comes from a first subregion of the image source, the third mirror being arranged to reflect only such radiation to a sensitive detector region which comes from a second subregion of the image source, the first subregion differing from the second subregion, and the fourth mirror being arranged to reflect radiation reflected by the third mirror, the third mirror being arranged on a rear side of the second mirror, a first mirror arranged to reflect the radiation generated by the image source; a second mirror arranged to reflect radiation reflected by the first mirror, the first mirror and the second mirror being spaced apart from one another and being parallel to one another or forming an angle of less than 90° between them, a third mirror and a fourth mirror, the first mirror being arranged to reflect only such radiation to a sensitive detector region which comes from a first subregion of the image source, the third mirror being arranged to reflect only such radiation to a sensitive detector region which comes from a second subregion of the image source, the first subregion differing from the second subregion, and the fourth mirror being arranged to reflect radiation reflected by the third mirror, the third mirror being arranged on a rear side of the second mirror, characterized in that an X-ray absorber material is arranged between the second mirror and the third mirror, the second mirror and the third mirror are configured on different sides of a support material absorbing X-rays. an X-ray absorber material is arranged between the second mirror and the third mirror, the second mirror and the third mirror are configured on different sides of a support material absorbing X-rays.
