постобработка 3D изображения

One of three stages of CBCT reconstruction, which consists of two distinct steps, HU correction and ring correction, and that applies to 3D images. The HU mapping provides a linear mapping of the arbitrary units of the raw CT numbers, which are the standard intensity scale used in computed tomography (air = -1000 HU and water = 0 HU). Ring correction is performed with a similar approach to that used by Sijbers and Postnov (Phys. Med. Biol. 49:14 (2004) but with an enhancement to account for partial or nonuniform rings. See also CBCT reconstruction.
