1. A system for reconstructing an image of an object, comprising:
a memory that stores a plurality of instructions; and
a processor assembly coupled to the memory and configured to execute the plurality of instructions to:
provide projection data of the object acquired by using an imaging system comprising an imaging field of view (FOV);
generate estimated image data indicative of a part of the object located outside the imaging FOV based on the provided projection data;
estimate virtual projection data, wherein the virtual projection data is estimated by forward projecting the estimated image data based on virtual settings of a virtual imaging system, wherein the virtual imaging system comprises a virtual FOV, wherein the part of the object located outside the imaging FOV is located inside the virtual FOV;
determine an imaging FOV slice thickness corresponding to the slice thickness of the projection data in the imaging FOV;
determine a virtual FOV slice thickness corresponding to the slice thickness of the virtual projection data in the virtual FOV, wherein the imaging FOV slice thickness is smaller than the virtual FOV slice thickness;
fuse the provided projection data that corresponds to the imaging FOV slice thickness with the virtual projection data that corresponds to the virtual FOV slice thickness; and
reconstruct a final image of the object based on the fused projection data.
