Abstract
In a method for correction of scatter radiation errors in radiography and computer tomography, using flat panel detectors, initially an estimation of a scatter radiation distribution Sr(y,z) is undertaken, and a standard correction term δpis subsequently calculated. Noise filtering of the standard correction term δpwith F(δp) is implemented and subsequently the noise-filtered standard correction term F(δp) is added to the logarithmized measured total projection data p. The noise filtering can be implemented adaptively dependent on a previously-determined local noise variance. The method can be implemented in a radiography system and/or by a computer for generation and/or processing of projective and/or tomographic exposures, with a memory containing program codes causing the computer in operation to execute the steps of the method.
