Book Description
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.

Book Description
Comprehensive medical imaging physics notes aimed at those sitting the first FRCR physics exam in the UK and covering the scope of the Royal College of Radiologists syllabus. Written by Radiologists, the notes are concise and clearly organised with 100's of beautiful diagrams to aid understanding. The notes cover all of radiology physics, including basic science, x-ray imaging, CT, ultrasound, MRI, molecular imaging, and radiation dosimetry, protection and legislation. Although aimed at UK radiology trainees, it is also suitable for international residents taking similar examinations, postgraduate medical physics students and radiographers. The notes provide an excellent overview for anyone interested in the physics of radiology or just refreshing their knowledge. This third edition includes updates to reflect new legislation and many new illustrations, added sections, and removal of content no longer relevent to the FRCR physics exam. This edition has gone through strict critique and evaluation by physicists and other specialists to provide an accurate, understandable and up-to-date resource. The book summarises and pulls together content from the FRCR Physics Notes at Radiology Cafe and delivers it as a paperback or eBook for you to keep and read anytime. There are 7 main chapters, which are further subdivided into 60 sub-chapters so topics are easy to find. There is a comprehensive appendix and index at the back of the book.

Book Description
After reading this book, imagers and CT technologists should better understand the capabilities of modern multidector CT scanners. Imagers and technologists must understand how their scanners operate in order to take advantage of new capabilities for optimizing protocols that minimize patient dose. In addition, the reader will be better prepared to recognize the pitfalls and artifacts that appear on CT imaging. Some of these are unfamiliar to most imagers and are the product of the large detector arrays offered on new CT scanners.

Book Description
This publication supports an interim solution to the dosimetric problems caused by modern computed tomography (CT) equipment, particular with respect to the wide X ray beam angles increasing seen in clinical practice. It reviews the development of current CT dose formalisms up to the current International Electrotechnical Commission (IEC) methodologies and presents practical measurement guidance in the implementation of new dosimetric methods needed with wide beam CT. Additional items of discussions are current approaches of the American Association of Physicists in Medicine in the USA to CT dosimetry as well as calibration aspects of CT dosimetric instrumentation. A summary describes the present status of CT dosimetry and provides recommendations for future action.

Book Description
This book addresses radiation protection of patients having digital radiography and computed tomography (CT) examinations. The literature on radiation doses to patients from these two modalities have reported that the doses to patients are high. As a result, the radiology community has focused on methods and procedures to keep these doses as low as reasonably achievable (ALARA) without compromising the diagnostic image quality. This book outlines the motivation for dose optimization in radiology, identifies and describes the ICRP principle of optimization, outlines the factors affecting the dose in digital radiography and in CT, and identifies and describes strategies used in digital radiography and in CT for dose optimization. This book is intended for all those working in digital radiography and CT environments including radiological technologists, and radiographers, radiologists, biomedical engineering technologists, and student medical physicists. It is best used as a supplement to radiologic science textbooks, and in particular, radiation protection textbooks. Furthermore, this book lays the foundations for students and practitioners engaged in research on dose reduction and dose optimization in radiology. · Provides practical and useful methods for optimization of doses from digital radiography and CT · Describes the International Commission on Radiological Protection (ICRP) principle of optimization · Outlines the factors affecting the dose in digital radiography and in computed tomography

Book Description
COMPUTED TOMOGRAPHY: PHYSICS AND TECHNOLOGY In the newly updated second edition of Computed Tomography: Physics and Technology A Self Assessment Guide, distinguished computed tomography (CT) educator Euclid Seeram delivers a completely revised and expanded collection of multiple-choice questions covering all relevant technological advances, including the use of artificial intelligence, in the field of CT. In the book, readers will find a focused emphasis on physics and technology — an area where students of this discipline have traditionally struggled. The questions are presented in a format similar to those found on the certification examinations of the American Registry of Radiologic Technologists (ARRT), the Canadian Association of Medical Radiation Technologists (CAMRT), and other professional medical imaging organizations around the world. The author has also included true-false questions, short answer questions, and relevant learning outcomes to aid students in their study of the subject. Readers will also find brief notes on: An introduction to computed tomography, including an overview of the field and a historical perspective Digital image processing and the physics of computed tomography Data acquisition principles and technology and image reconstruction fundamentals Deep learning image reconstruction, the major equipment components of a computed tomography scanner, and image post-processing and visualization Multislice CT: Principles and Technology Image quality considerations CT Dosimetry and dose optimization strategies Quality control Perfect for radiological technology and diagnostic radiography students and practitioners, Computed Tomography: Physics and Technology A Self Assessment Guide, will also earn a place in the libraries of biomedical engineering students and radiology residents in training.
