内容説明
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
