Abstract:
1. A system for generating a sinogram, comprising: a plurality of X-ray source points arranged around a scanning region; a first set of detectors arranged to detect X-rays transmitted through the scanning region; a second set of detectors arranged to detect X rays scattered from the scanning region; and a processing system for receiving unattenuated X-ray beam intensity data from the plurality of X-ray source points, for receiving attenuated X-ray beam intensity data from the first set of detectors, and for generating said sinogram from a function of said unattenuated X-ray beam intensity data and attenuated X-ray beam intensity data, wherein said sinogram comprises data arranged in an array with a pixel number along one axis and a source angle, corresponding to one of said plurality of X-ray source points, along a second axis.
