Abstract
A computed tomography imaging scanner () acquires helical cone beam projection data for a volume of interest () using at least two source trajectory helices. A reconstruction processor () reconstructs the projection data for each helix to generate a corresponding time skewed image representation. A voxel time processor () computes an acquisition time for each voxel in each time skewed image representation. A voxel interpolator () computes an interpolated voxel value for each voxel based on values of the voxel in the time skewed image representations and corresponding voxel acquisition times. In an electronic embodiment, the computed tomography scanner () includes an x-ray source () with an axially oriented cylindrical anode (), an electron source () irradiating the cylindrical anode () to produce an x-ray beam (), and an electron beam deflector () that deflects the electron beam along the anode () to axially sweep the x-ray beam.
