Computed Tomography: Fundamentals, System Technology, Image Quality, Applications
This book provides a comprehensive and user-friendly description of the theoretical and technical essentials of computed tomography (CT) for a wide readership. It treats in detail all characteristic parameters relevant for image quality and all performance features significant for clinical applications. Readers will thus be informed how to optimally use a CT system depending on their different diagnostic requirements. This includes a detailed discussion about the dose required and about dose measurement as well as how to reduce dose in CT.
This book is intended for all those who work daily, regularly or even only occasionally with CT: doctors, technologists, engineers, service technicians and physicists.
A glossary describes all the important technical terms in alphabetical order.
