Patent ID: 8121248

Claim:
A non-transitory computer readable medium having a computer program stored thereon and representing a set of instructions that when executed by a computer causes the computer to: cause an x-ray source to emit x-rays toward different portions of an x-ray detector, wherein one portion of the x-ray detector comprises a plurality of detector cells having a first spectral property, and wherein another portion of the x-ray detector comprises a plurality of detector cells having a second spectral property; acquire two sets of projection data of a given plane from the two different portions of the x-ray detector during a common rotation of the x-ray detector; cause the x-ray source to emit x-rays in an alternating pattern between a detector cell of the first spectral property and a detector cell of the second spectral property along a length of the x-ray detector; and create an image from the two sets of projection data, wherein the detector cells of the first spectral property and the detector cells of the second spectral property are interleaved along the length of the x-ray detector.
