1. A system configured to process projection data, comprising:
at least one non-transitory storage medium including a set of instructions; and
at least one processor in communication with the at least one non-transitory storage medium, wherein when executing the set of instructions, the at least one processor is configured to direct the system to:
obtain first projection data corresponding to a first area of a subject;
obtain second projection data corresponding to a second area of the subject, the first area at least partially overlapping with the second area in an overlapping area;
determine registered first projection data by registering the first projection data to the second projection data with respect to the overlapping area, wherein the registration of the first projection data to the second projection data is a two-dimensional registration;
determine a scatter component based on the registered first projection data and the second projection data, the scatter component representing a scatter distribution related to the second projection data; and
determine corrected second projection data based on the scatter component and the second projection data.
