Intra-detector scatter correction methods to improve X-ray images. The method of correcting an X-ray image includes: receiving an original two-dimensional X-ray image; calculating a theoretical scattered image for a array of detector pixels by generating a theoretical point spread (TPS) function of a single pixel for a single line array of detector pixels, based on a system parameter; aggregating the TPS function into a full rotation of line arrays, so as to generating a TPS function for a 2-dimensional array of pixels; and applying the TPS function for a 2-dimensional array of pixels to a plurality of pixels in the detector; and then subtracting the theoretical scattered image from the original two-dimensional X-ray image, so as to create an improved X-ray image.
