Abstract
A CT scanner for multiple energy CT scanning of a subject having an X-Ray source adapted to rotate about the subject; and a detector array, having a plurality of detector elements, adapted to acquire attenuation data for X-Rays that have been attenuated by a subject disposed between said X-Ray source and said detector array, said detector array comprising at least two types of detector element, which are differ by their spectral response. The scanner is adapted to generate images associated with the different X-Ray energy spectra.

A CT scanner for multiple energy CT scanning of a subject comprising:
- an X-Ray source configured to rotate about the subject;
- a detector array having a plurality of detector elements, said detector array is configured to acquire attenuation data for X-Rays that have been attenuated by the subject disposed between said X-Ray source and said detector array, said detector array comprising:
- at least one region of detector elements having a first spectral response;
- and
- at least one region of detector elements having a second spectral response;
- and
- a controller configured to axially increment the position of the subject respective to said X-Ray source and said detector array such that at least some voxels in the subject that were on lines from said X-Ray source to said detector elements having first spectral response move to lines from said X-Ray source to said detector elements having second spectral response.
