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 …

Graphics processing units (GPUs) are used today in a wide range of applications, mainly
because they can dramatically accelerate parallel computing, are affordable and energy …

An iterative algorithm, based on recent work in compressive sensing, is developed for
volume image reconstruction from a circular cone-beam scan. The algorithm minimizes the …

Purpose To assess the relationship between radiation dose and change in a set of
mathematical intensity-and texture-based features and to determine the ability of texture …

High radiation dose in computed tomography (CT) scans increases the lifetime risk of cancer
and has become a major clinical concern. Recently, iterative reconstruction algorithms with …

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

This book really shows how registration works: the flip-book appearing at the top right
corners shows a registration of a human knee from bent to straight position (kee** bones …

Spatial resolution is one of the most important parameters objectively defining image quality,
particularly in dental imaging, where fine details often have to be depicted. Here, we review …

The graphics processing unit (GPU) has emerged as a competitive platform for computing
massively parallel problems. Many computing applications in medical physics can be …

Background and purpose The use of cone beam computed tomography (CBCT) for
performing dose calculations in radiation therapy has been widely investigated as it could …
