Abstract
A spectral computed tomography (CT) ordered subsets (OS) reconstruction method using two sets of projection data having a different number of views is provided. The method includes obtaining a first set of projection data that includes single-energy CT data for a first number of views, obtaining a second set of projection data that includes spectral CT data for a second number of views, wherein the first and second numbers are integers and the second number is smaller than the first number, partitioning the first set of projection data into N equal-sized subsets of projection data, including the second set of projection data in each of the N subsets of projection data to generate N expanded subsets of projection data, and performing OS reconstruction with the N expanded subsets of projection data to generate a reconstructed CT image.
