1. A method for using in an X-ray image device, comprising:
forming a modulated X-ray image, comprising:
acquiring X-rays through a collimator module and an imaged object in sequence to generate an X-ray image group including a plurality of X-ray images;
wherein the collimator module includes one or more pairs of collimators each of which includes collimators arranged within a distance in a first direction and the acquisition is performed during a movement of the collimator module in the first direction; and
determining the modulated X-ray image based on the plurality of X-ray images, the modulated X-ray image including dark stripes and bright stripes.
