The Physics of CT Dosimetry: Ctdi and Beyond

This book explores the physics of CT dosimetry and provides practical guidance on best practice for medical researchers and practitioners. A rigorous description of the basic physics of CT dosimetry is presented and illustrates flaws of the current methodology.

It also contains helpful (and rigorous) shortcuts to reduce the measurement workload for medical physicists. The mathematical rigor is accompanied by easily-understood physical explanations and numerous illustrative figures.

Features:

• Authored by a recognised expert in the field and award-winning teacher
• Includes derivations for tube current modulation and variable pitch as well as stationary table techniques
• Explores abnormalities present in dose-tracking software based on CTDI and presents methods to correct them

Robert L. Dixon, Ph.D, FACR, FAAPM is Professor Emeritus in the Department of Radiology, Wake ForestUniversity School of Medicine, USA and holds a Ph.D. in Nuclear Physics.

He has taught physics and medical physics for decades, and is a recipient of the Radiology Department’s Teaching Excellence Award. He is also a past president of the American Association of Physicists in Medicine (AAPM) as well as past Chairman of the AAPM Science Council and CT Committee; and is a past Vice President of RSNA. He has published many papers on CT dosimetry in the journal Medical Physics and is a five-time winner of the SEAAPM Best Publication Award.

Prof. Dixon is a member of the IEC MT30 CT committee; is a designated US CT Expert (ANSI); and has been an invited keynote speaker at multiple International Conferences. He has also been a member of the Governing Board and the Executive Committee of the American Institute of Physics (AIP), and has received the Distinguished Service Award and the Lifetime Achievement Award of the American Board of Radiology (ABR).

He was also an airshow performer (1991-2006) flying former military aircraft including an ex- Soviet Air Force jet.
