Introduction

Since the discovery of X-rays by Wilhelm Conrad Röntgen in 1895, medicine has lived a revolution that influenced all of its disciplines. The sudden possibility to have a glimpse inside of the human body without incising it opened new ways in medical examining and diagnostics. Today, modern medicine without imaging has become unthinkable. Radiological methods are used to perform diagnosis, to prepare surgical interventions, to follow the state of a patient and even for treatment in the context of radiotherapy and angiographic interventions.
