A computed tomography (CT) system can generate an image of an object based on a partial scan over a range of angles. Some embodiments of a CT system can determine a partial- scan orientation based at least in part on image data obtained from a preliminary and/or surface scan of the object. The partial-scan orientation can include a range of angles over which the CT system will perform the CT scan. In some embodiments, the range of angles is comprised of one contiguous range of angles. In some embodiments, the range of angles can comprise two or more noncontiguous ranges of angles. In certain embodiments, the image generated has a higher spatial resolution than an image corresponding to a partial scan over a different range that is similarly sized as, but differently oriented from, the first range. |
