Method for producing scattering ray raster or collimator with ray absorption material

[0031] A typical situation during the radiographing of an object 3 is schematically depicted in FIG. 1 . The object 3 is located between an x-ray tube focus 1 which can be regarded as a point x-ray source and a detection surface 7 . The x-ray beam 2 emitted by the focal point 1 of the x-ray source spreads linearly in the direction of the x-ray detector 7 and passes through the object 3 there. The primary ray 2a emitted by the X-ray focal point 1 passing through the object 3 and impinging on the detection surface 7 produces a spatially resolvable attenuation value distribution on the detection surface 7 due to the object 3 . A part of the x-rays 2 emitted by the x-ray focus 1 is scattered in the object 3 . The resulting scattered radiation 2 b has a negative effect on the desired image information and significantly deteriorates the signal-to-noise ratio when impinging on the detector 7 . To improve the image quality, a scattered radiation grid is then arranged upstream of the...
