摘要： A method of scanning a subject to be imaged is presented. The method includes acquiring projection data from a first region of a pixel, where the first region has a first area. Additionally, the method includes acquiring projection data from a second region of the pixel, where the second region has a second area. The method also includes combining projection data from the first and second regions to obtain composite projection data for the pixel. Computer-readable medium and systems that afford functionality of the type defined by this method are also contemplated in conjunction with the present technique.

摘要： A method for reconstructing image data from measured sinogram data acquired from a CT system is provided. The CT system is configured for industrial imaging. The method includes pre-processing the measured sinogram data. The pre-processing includes performing a beam hardening correction on the measured sinogram data and performing a detector point spread function (PSF) correction and a detector lag correction on the measured sinogram data. The pre-processed sinogram data is reconstructed to generate the image data.
