15. A method for processing X-ray data, comprising:
identifying, from the X-ray data, regions having required information and regions not having required information;
calibrating the X-ray data based only on regions having the identified information and not on the regions not having required information;
processing the calibrated X-ray data into one or more processed X-ray images; and
issuing instructions to a scan engine to modify a spatial resolution of a scan based upon the X-ray data, wherein the spatial resolution is modified by generating a first spatial resolution in a scan direction and a second spatial resolution in a scan plane, the first spatial resolution being different than the second spatial resolution.
