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.

Euclid Seeram was formerly the Program Head of the Medical Imaging Degree at the British Columbia Institute of Technology, British Columbia, Canada.

Euclid is an active member of the Canadian Radiation Protection Association

Currently serves as adjunct associate professor at Monash University; adjunct professor at Charles Sturt University; and Adjunct Associate Professor, University of Canberra; in Australia. He is also a regular guest lecturer in Radiographic Sciences; Computed Tomography Physics and Technology for VCA Education Solutions for Health Professionals; Toronto, Ontario, Canada.

Euclid has published more than 62 papers in peer-reviewed radiologic technology journals and has had 27 textbooks published on computed tomography, computers in radiology, radiographic instrumentation, digital radiography, and radiation protection.

He is a founding member of the Journal of Medical Imaging and Radiation Sciences and is now on several international editorial boards for 5 Journals of Medical Imaging

Euclid was recently awarded the Charles Sturt University 2022 Alumni of the year for professional achievement. This award "recognizes alumni who are professionally making a significant and positive impact on their communities, their industry, or the world."

Euclid's current research interests are related to radiation dose optimization in computed tomography and digital radiography imaging systems, as well as in radiation protection related to diagnostic imaging.
