This volume serves as a study guide and revision resource for postgraduate students preparing for examinations in radiotherapy physics. 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, radiotherapy has continued to advance rapidly, with significant developments in treatment delivery technologies, imaging for radiotherapy, treatment planning methodologies, dosimetry techniques and quality assurance practices. 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 forty-seven solved problems are presented across ten chapters covering core topics, including External Beam Therapy Equipment, Photon Beam Physics, Radiation Dosimetry, Treatment Planning for External Beam Radiotherapy, and External Beam Commissioning and Quality Assurance. 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 diagnostic imaging physics, nuclear medicine physics and radiation protection. Features:Consolidates concepts and assists in the understanding and applications of theoretical concepts in medical physicsSuitable as a revision tool for postgraduate students sitting medical physics, radiation oncology and radiology science examinationsEach chapter provides examples, notes and references for further reading to enhance understanding.
