1. A system, comprising:
at least one storage device including a set of instructions; and
at least one processor configured to communicate with the at least one storage device, wherein when executing the set of instructions, the at least one processor is configured to direct the system to perform operations including:
obtaining a preliminary image and scanning data of a subject acquired using a scanner;
determining a regularization parameter for a regularization item of an objective function based at least in part on the scanning data, wherein the regularization parameter includes a component characterizing a feature of the subject; and
generating an image of the subject by reconstructing the preliminary image based on the objective function, wherein the component of the regularization parameter relates to attenuation information and boundary information of the subject, and the attenuation information is combined with a spatial sensitivity of the scanner via a spatial sensitivity map that includes the spatial sensitivity of the scanner and the attenuation information of the subject.
