Numerical results on X-ray small-angle scattering imaging. (a) An image collected with a high collimation aspect and a small object-detector distance (2.5 cm), (b) an image with a low collimation aspect and a small object-detector distance (2.5 cm), (c) an image with a low collimation aspect and a large object-detector distance (17.5 cm), (d) the difference between (a) and (b), and (e) the difference between (b) and (c).
