1. A method for image reconstruction, comprising:
determining an image matrix corresponding to a scanned region;
dividing the image matrix into a plurality of sub-image matrixes, each sub-image matrix corresponding to a sub-scanned region of the scanned region;
determining a main computing node and a plurality of subordinate computing nodes;
transforming at least a portion of the image matrix to generate at least one transformed matrix, wherein a size of the at least one transformed matrix is smaller than a size of the image matrix before transforming, the image matrix corresponds to a pair of imaging modules of an imaging device, and the imaging device includes a plurality of imaging modules arranged along an axis of the imaging device;
reconstructing the image matrix based on the at least one transformed matrix; and
for each of the at least one sub-image matrix, assigning a subordinate computing node of the plurality of subordinate computing nodes to the sub-image matrix, wherein:
each subordinate computing node is configured to reconstruct the corresponding sub-image matrix;
the main computing node is configured to generate the reconstructed image matrix based on the reconstructed sub-image matrixes generated by the subordinate computing nodes.
