摘要
Embodiments of methods and/or apparatus for 3-D volume image reconstruction of a subject, executed at least in part on a computer for use with a digital radiographic apparatus can obtain image data for 2-D projection images over a range of scan angles. For each of the plurality of projection images, an enhanced projection image can be generated. In one embodiment, through the application of a resolution increasing interpolator, a prescribed CBCT routine scanning mode with preset binning can increase a spatial resolution, Nyquist frequency or MTF.
