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 …

CT imaging is widely used in medical science over the last decades. The process of CT
image reconstruction depends on many physical measurements such as radiation dose …

We report here on recent developments and advances in pore-scale X-ray tomographic
imaging of subsurface porous media. Our particular focus is on immiscible multi-phase fluid …

The rapid increase in the performance of graphics hardware, coupled with recent
improvements in its programmability, have made graphics hardware a compelling platform …

This revised and updated second edition–now with two new chapters-is the only book to
give a comprehensive overview of computer algorithms for image reconstruction. It covers …

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 …

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

In this work, we present a survey of the different parallel programming models and tools
available today with special consideration to their suitability for high-performance …

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 …

Sparse-view CT reconstruction algorithms via total variation (TV) optimize the data iteratively
on the basis of a noise-and artifact-reducing model, resulting in significant radiation dose …
