    X-ray/CT Technique - Introduction

     Learn the most important basics about the X-ray and CT technique in understandable language, with a special focus on physics. Various CT techniques are discussed, including the latest CT development 'Photon-Counting Detector CT' (operational in hospitals since 2021).

    It is particularly recommended that you read this module before you start with the specific lectures on the various X-ray examinations (for example X-Shoulder) and CT examinations (for example CT Abdomen General).
    If you want to know more about the dangers of ionizing radiation, the Ionizing Radiation module may be interesting to read.
