Computed Tomography by
The book offers a comprehensive and user-oriented description of the theoretical and technical system fundamentals of computed tomography (CT) for a wide readership, from conventional single-slice acquisitions to volume acquisition with multi-slice and cone-beam spiral CT. It covers in detail all characteristic parameters relevant for image quality and all performance features significant for clinical application. Readers will thus be informed how to use a CT system to an optimum depending on the different diagnostic requirements. This includes a detailed discussion about the dose required and about dose measurements as well as how to reduce dose in CT. All considerations pay special attention to spiral CT and to new developments towards advanced multi-slice and cone-beam CT. For the third edition most of the contents have been updated and latest topics like dual source CT, dual energy CT, flat detector CT and interventional CT have been added. The enclosed CD-ROM again offers copies of all figures in the book and attractive case studies, including many examples from the most recent 64-slice acquisitions, and interactive exercises for image viewing and manipulation. This book is intended for all those who work daily, regularly or even only occasionally with CT: physicians, radiographers, engineers, technicians and physicists. A glossary describes all the important technical terms in alphabetical order.

Computed Tomography for Technologists: a Comprehensive Text by
Covering only what CT technologists need to know, this all-in-one solution helps students develop the knowledge and decision-making skills they need for clinical practice while preparing them for the ARRT registry exam. Organized around the four major ARRT content categories (patient care, safety, image production, and procedures), the fully updated 2nd Edition takes an easy-to-understand approach that combines real-world scenarios, and proven pedagogy to help students master the content of the course. NEW ! The latest ARRT and ASRT standards are incorporated to fully prepare students for the registry exam. NEW! Up-to-date content on patient radiation dosing includes methods to reduce doses, such as adaptive statistical iterative reconstruction (ASIR) and factors associated with expanded MDCT that contribute to the dose. EXPANDED! The book's robust online student resources now include new audio flashcards, a new audio glossary, and new animations, as well as an image bank and exam simulator. Clinical Application boxes use real-life scenarios to illustrate and explain concepts. In-text learning aids , including key terms, key concepts boxes, review questions, an end-of-the book glossary, and recommended readings, reinforce learning. Examples of Exam Protocols summarize appropriate protocols and procedures for examining major anatomical areas. CT Cross-Sectional Slices, accompanied by shaded diagrams and a reference image, appear in the Cross-Sectional Anatomy section. eBook available for purchase. Fast, smart, and convenient, today's eBooks can transform learning. These interactive, fully searchable tools offer 24/7 access on multiple devices, the ability to highlight and share notes, and more
Computed tomography: approaches, applications, and operations by
This book offers a comprehensive and topical depiction of advances in CT imaging. CT has become a leading medical imaging modality, thanks to its superb spatial and temporal resolution to depict anatomical details. New advances have further extended the technology to provide physiological information, enabling a wide and expanding range of clinical applications. The text covers the latest advancements in CT technology and clinical applications for a variety of CT types and imaging methods. The content is presented in seven parts to offer a structure across a board coverage of CT: CT Systems, CT Performance, CT Practice, Spectral CT, Quantitative CT, Functional CT, and Special Purpose CT. Each contain chapters written by leading experts in the field, covering CT hardware and software innovations, CT operation, CT performance characterization, functional and quantitative applications, and CT systems devised for specific anatomical applications. This book is an ideal resource for practitioners of CT applications in medicine, including physicians, trainees, engineers, and scientists.
