11. A system, comprising:
at least one storage medium including a set of instructions; and
at least one processor configured to communicate with the at least one storage medium, wherein when executing the set of instructions, the system is configured to:
determine functional statuses of a plurality of detector subunits of an imaging device;
divide the plurality of detector subunits into a first group and a second group based on the functional status of the respective detector subunits, wherein the functional status of the detector subunits in the first group is functional, and the functional status of the detector subunits in the second group is non-functional;
generate reconstruction data based on scan data collected by the detector subunits in the first group; and
reconstruct an image based on the reconstruction data.
