The obesity epidemic in the adult and pediatric populations affects all aspects of health care,
including diagnostic imaging. With the increasing prevalence of obese and morbidly obese …

X-ray computed tomography (CT) imaging of patients with metallic implants usually suffers
from streaking metal artifacts. In this paper, we propose a new projection completion metal …

Ring artifacts in cone beam computed tomography (CBCT) images are caused by pixel gain
variations using flat-panel detectors, and may lead to structured non-uniformities and …

Most small-animal X-ray computed tomography (CT) scanners are based on cone-beam
geometry with a flat-panel detector orbiting in a circular trajectory. Image reconstruction in …

We introduce an efficient ring artifact correction method for a cone-beam computed
tomography (CT). In the first step, we correct the defective pixels whose values are close to …

The reconstructed slice quality of flat-detector computed tomography (CT) is often disturbed
by concentric-ring artifacts. Since concentric rings in CT slices appear as straight stripes …

The development of energy-resolving photon-counting detectors provides a new approach
for obtaining spectral information in computed tomography. However, the responses of …

Background In x‐ray computed tomography (CT), the gain inconsistency of detector units
leads to ring artifacts in the reconstructed images, seriously destroys the image structure …

Ring artifacts can occur in reconstructed images from x-ray Computerized Tomography (CT)
as full or partial concentric rings superimposed on the scanned structures. Due to the data …

Ring artifacts in computed tomography (CT) images degrade image quality and obscure the
true shapes of objects. While several correction methods have been developed, their …
