This paper presents a mathematical characterization and analysis of beam-hardening artefacts in X-ray computed tomography (CT). In the field of dental and medical radiography, metal artefact reduction in CT is becoming increasingly important as artificial prostheses and metallic implants become more widespread in ageing populations. Metal artefacts are mainly caused by the beam-hardening of pol...

Anthropomorphized, or human-like artefacts, have been used in teaching and training of medical skills for a long time. The most famous artefact used today is probably the Resusci ® Anne CPR training manikin, which is used for training of resuscitation skills. However, what has changed over the lifespan of these artefacts is the level of human-like features in them. All around the globe, highly ...

In recent years, the clinical importance of cardiac magnetic resonance (CMR) imaging has increased dramatically. As a consequence, more clinicians need to become familiar with this imaging modality, including its technical challenges. MR images are obtained through a physical process of proton excitation and the reception of resonating signals. Besides these physical principles, the motion of t...

Overview and Motivation Due to the rising demand for individualised software products and software-intensive systems (e.g., mobile phone or automotive software), organizations are faced with the challenge to provide a diversity of software systems at low costs, in short time, and with high quality. Software product line engineering is the approach for tackling this challenge and has proven its ...
