There is an increasing interest in iterative reconstruction (IR) as a key tool to improve quality
and increase applicability of x-ray CT imaging. IR has the ability to significantly reduce …

Since scattered radiation in cone‐beam volume CT implies severe degradation of CT
images by quantification errors, artifacts, and noise increase, scatter suppression is one of …

Accurate scatter correction is required to produce high-quality reconstructions of x-ray cone-
beam computed tomography (CBCT) scans. This paper describes new scatter kernel …

X-ray scatter is a major cause of image quality degradation in dimensional CT. Especially, in
case of highly attenuating components scatter-to-primary ratios may easily be higher than 1 …

Purpose X‐ray scattering leads to CT images with a reduced contrast, inaccurate CT values
as well as streak and cupping artifacts. Therefore, scatter correction is crucial to maintain the …

X-ray computed tomography (XCT) is increasingly being used for evaluating quality and
conformance of complex products, including assemblies and additively manufactured parts …

The main components of scatter correction procedures are scatter estimation and a scatter
compensation algorithm. This paper completes a previous paper where a general …

A new method is proposed for scatter-correction of cone-beam CT images. A coarse
reconstruction is used in initial iteration steps. Modelling of the x-ray tube spectra and …

Purpose Scatter is a major factor degrading the image quality of cone beam computed
tomography (CBCT). Conventional scatter correction strategies require handcrafted …

Purpose: Applications of cone‐beam CT (CBCT) to image‐guided radiation therapy (IGRT)
are hampered by shading artifacts in the reconstructed images. These artifacts are mainly …
