Artefacts are common in today's cone beam CT (CBCT). They are induced by discrepancies
between the mathematical modelling and the actual physical imaging process. Since …

Methods to overcome metal artifacts in computed tomography (CT) images have been
researched and developed for nearly 40 years. When X-rays pass through a metal object …

In this paper, we present a semi-supervised deep learning approach to accurately recover
high-resolution (HR) CT images from low-resolution (LR) counterparts. Specifically, with the …

In the presence of metal implants, metal artifacts are introduced to x-ray computed
tomography CT images. Although a large number of metal artifact reduction (MAR) methods …

Computed tomography (CT) has been widely used for medical diagnosis, assessment, and
therapy planning and guidance. In reality, CT images may be affected adversely in the …

Purpose: While modern clinical CT scanners under normal circumstances produce high
quality images, severe artifacts degrade the image quality and the diagnostic value if metal …

Despite universal consensus that computed tomography (CT) overwhelmingly benefits
patients when used for appropriate indications, concerns have been raised regarding the …

Objectives: To briefly review the mathematical background of beam‐hardening artifacts in
cone‐beam computed tomography (CBCT)‐reconstruction and to investigate geometrical …

Scoliosis is a common disease of the spine and requires regular monitoring due to its
progressive properties. A preferred indicator to assess scoliosis is by the Cobb angle, which …

Metal streak artifacts are an important problem in X-ray computed tomography. A high-
resolution 2D fan-beam computed tomography simulator is presented. Several potential …
