Claim 15:
16. A method implemented on a computing device having a processor and a computer-readable storage device, the method comprising:
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.
