X‐ray scatter correction algorithm for cone beam CT imaging
Abstract
Developing and optimizing an x‐ray scatter control and reduction technique is one of the major challenges for cone beam computed tomography (CBCT) because CBCT will be much less immune to scatter than fan‐beam CT. X‐ray scatter reduces image contrast, increases image noise and introduces reconstruction error into CBCT. To reduce scatter interference, a practical algorithm that is based upon the beam stop array technique and image sequence processing has been developed on a flat panel detector‐based CBCT prototype scanner. This paper presents a beam stop array‐based scatter correction algorithm and the evaluation results through phantom studies. The results indicate that the beam stop array‐based scatter correction algorithm is practical and effective to reduce and correct x‐ray scatter for a CBCT imaging task.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
