1. A method implemented on a computing device having at least one processor, at least one computer-readable storage medium, and a communication port connected to an imaging device, the method comprising:
obtaining image data, wherein the image data includes projection data and is generated by the imaging device;
determining an objective function associated with a target image based on the image data, the objective function including a difference model, wherein the difference model represents a difference between a projection of the target image and the image data, wherein the difference model is determined based on a weighting matrix, and the weighting matrix is determined based on an extended Tam window; and
reconstructing the target image by performing a plurality of iterations based on the objective function.
