1. A method implemented on a computing device including a processor and a storage media, the method comprising:
obtaining first image data of a subject related to a first scan of the subject, the first scan being of a first type of scan;
reconstructing a first image of the subject based on the first image data;
generating a dose plan of a second scan based on the first image, the second scan being of a second type of scan; and
obtaining second image data of the subject related to the second scan of the subject, the second scan being performed according to the dose plan, wherein the generating a dose plan of a second scan based on the first image comprises:
identifying at least one region of interest (ROI) in the first image;
determining the dose plan of the second scan based on the at least one ROI, the dose plan including a first dose corresponding to the ROI and a second dose corresponding to a region outside the ROI, and the first dose being higher than the second dose, the second image data corresponding to the ROI and the region outside the ROI;
reconstructing a second image of the subject based on the second image data; and
performing an attenuation correction on the first image based on the second image.
