This volume serves as a study guide and revision resource for postgraduate students preparing for examinations in diagnostic imaging. The problems and solutions presented reflect the typical syllabi adopted by universities and training programmes worldwide. This invaluable study guide should be used in conjunction with other key textbooks in the field to provide additional learning opportunities.

Since the publication of the first edition, diagnostic imaging has continued to advance rapidly, with significant developments in computed tomography, artificial intelligence and radiomics. In response to these developments, the second edition has been carefully reviewed and updated. Existing problems have been refined, solutions have been strengthened and expanded where appropriate, and selected content has been revised to better reflect current clinical practice and evolving standards.

One hundred and sixty-two solved problems are presented across ten chapters covering core topics, including X-Ray Production, Digital Radiography, Image Quality, Computed Tomography, Magnetic Resonance Imaging, Ultrasound, Radiation Protection, Radiobiology, Artificial Intelligence and Radiomics. The problems are designed to illustrate and augment the underlying theory, while reinforcing fundamental principles to enhance learning and information retention.

This book forms part of a four-volume set of medical physics problems and solutions. The companion volumes address radiotherapy physics, nuclear medicine physics and radiation protection.

Features:

• Consolidates concepts and assists in the understanding and applications of theoretical concepts in medical physics
• Suitable as a revision tool for postgraduate students sitting medical physics, radiation oncology and radiology science examinations
• Each chapter provides examples, notes and references for further reading to enhance understanding.

Professor Ng has served as a consultant to the International Atomic Energy Agency (IAEA) and as an expert consultant to the International Commission on Non-Ionizing Radiation Protection (ICNIRP). Professor Ng is the founding and emeritus president of the South East Asian Federation of Organizations for Medical Physics (SEAFOMP), a past president of the Asia-Oceania Federation of Organizations for Medical Physics (AFOMP), and the founder of the ASEAN College of Medical Physics (ACOMP), where he currently serves as the director.

Jeannie Hsiu Ding Wong, PhD, DIMPCB, is a Professor in the Faculty of Medicine at Universiti Malaya and Manager of the Medical Physics Centre at Universiti Malaya Medical Centre. Trained in biomedical engineering and medical physics at Universiti Malaya and the University of Wollongong, she has devoted her career to advancing radiation dosimetry and the safe, optimised use of medical imaging technologies. Her work reflects a sustained commitment to scientific innovation and patient safety. In recognition of her prominent contributions, Professor Wong received the SEAFOMP Young Leader Award in 2019 and holds Fellowships from the Malaysian Institute of Physics and the Malaysian Association of Medical Physics. Her scholarly output includes over 100 peer-reviewed papers, several book chapters, and a co-authored textbook. She has secured RM 2.4 million in research grants and delivered over 50 invited lectures worldwide.

Beyond scholarship, Professor Wong is deeply engaged in mentoring, education, and professional formation. As a long-standing educator and former coordinator of the Master of Medical Physics Programme, she has supervised over 70 postgraduate candidates. She has organised numerous workshops on radiation dosimetry and scientific writing, nurturing generations of medical physicists. Her research leadership spans breast radiomics, artificial intelligence, and interventional radiology safety.

Professor Wong has served as a Principal Investigator for the International Atomic Energy Agency (IAEA). She is actively involved in regional leadership as a Scientific Committee Member for the Asia-Oceania Federation of Organizations for Medical Physics (AFOMP) and Secretary of the Institute of Physics Malaysia, Medical Physics Division.

Geoffrey D. Clarke, PhD, FACR, FAAPM, is Professor of Radiology at the University of Texas at San Antonio’s (UTSA) Long School of Medicine. He is also the Associate Director and Chief of the MRI Division at the Research Imaging Institute at UTSA. Dr. Clarke is a Fellow of the American College of Radiology (ACR), American Association of Physicists in Medicine (AAPM), and the American College of Medical Physics (ACMP).
