Foreword
Dr Euclid Seeram is a recognized educator in the field of radiographic sciences, including computed tomography (CT) physics and instrumentation for radiologic technologists/radiographers. He has published over 22 textbooks on various topics related to these two subjects. His textbooks can be found in universities and colleges around the world that offer medical imaging and radiographic science programs. He has a very well‐developed approach in all his textbooks that allows the reader to understand complex topics.
Dr Seeram has decades of experience in the teaching radiographic sciences and CT. Euclid is also a highly regarded researcher in this field, gaining a PhD in digital radiography and radiation dose management strategies. He has continued to work and research in this area. Euclid is also a highly sought‐after speaker and provides highly engaging talks and presentations on radiographic sciences and CT. The impact of Euclid's texts, journal articles, and presentations has had on radiologic technologists/radiographers, other related individuals, and medical physicists in their understanding of radiographic sciences and CT, cannot be understated.
The development of the technologies that underpin radiological science continues to grow rapidly and at an increasing rate. Students need to understand these technologies and the implications of these technologies in clinical practice. The approach undertaken by Dr Seeram in this text, A Comprehensive Guide to Radiographic Sciences and Technology, is to provide readers with clearly defined chapters on several related topics. The chapters and sections of this book are logically structured so the readers/learners can progress their understanding. Of growing importance in radiographic sciences, and often misunderstood, is the understanding of the radiation dose/image quality relationship of digital radiography. This area has a strong focus in this textbook. Furthermore, the knowledge gained from studying the subject matter covered in this book will benefit technologists/radiographers in clinical practice in order to provide tangible benefits to their patients.
I have been fortunate to know Dr Seeram for over 20 years, initially as his PhD supervisor, and now as a coresearcher, colleague, and friend/mate. Euclid continues to amaze me on his dedication and passion to educate radiologic technologists/radiographers and his drive to continue writing. Euclid must be commended for his continued efforts in making radiographic sciences, and CT knowledge easy to understand by students and practitioners.

Preface
Radiographic sciences and technology include a wide range of topics essential for radiography/radiological technology curriculum offered by educational institutions (colleges, universities, and institutes of technology) around the world. Additionally, radiography/radiological technology/medical imaging professional organizations for radiographer/technologist education and training, such as, for example, the American Association of Radiologic Technologists (ASRT) and the Canadian Association of Medical Radiation Technologists (CAMRT) offer curriculum guidelines for educational institutions to use as guiding principles for core clinical competencies. More details of related activities are highlighted in Chapter 1.
This book includes 13 chapters organized into 6 sections as follows:
Section 1: Chapters 1 and 2
Section 2: Basic Radiographic Sciences and Technology
Section 3: Computed Tomography: Basic Physics and Technology
Section 4: Continuous Quality Improvement
Section 5: Picture Archiving and Communications Systems (PACS) and Imaging Informatics
