Abstract
A method is provided for processing a dual-energy CT scan image, which includes filtering the pixels in a dual-energy CT scan image to obtain pixels to be grouped; grouping the pixels to be grouped into a plurality of pixel groups based on the positions of the pixels to be grouped in the dual-energy CT scan image; performing material decomposition on the pixels in each pixel group; and determining the object corresponding to each pixel group based on the results of material decomposition. By using the method, the scan time and the X-ray dose radiated to a target (e.g., a user to be diagnosed) are reduced.
