Correction of CT attenuation data using fan beam reprojections
In an x-ray computed tomography system which acquire x-ray attenuation data using a fan beam of radiation, corrections for beam hardening are made by reprojecting the CT image data. The reprojection computations are reduced by rotating and warping the CT image data, and then performing a parallel re...

| description | In an x-ray computed tomography system which acquire x-ray attenuation data using a fan beam of radiation, corrections for beam hardening are made by reprojecting the CT image data. The reprojection computations are reduced by rotating and warping the CT image data, and then performing a parallel reprojection along columns of data. |
