註釋 Radioactive Isotopes in the Localization of Tumours covers the proceedings of the 1967 International Nuclear Medicine Symposium, held at the Imperial College of Science and Technology, London, organized by the Institute of Cancer Research in association with the Royal Marsden Hospital. This book is composed of three parts encompassing 40 chapters. After an introduction to the principles of scanning and physical problems, this book goes on describing the physical aspects of mechanical scanning systems, collimators, cameras, autofluorescope, and photoscanner. The second part reviews the radioactive materials for tumor localization. This part specifically examines the technique of regional oxygenation, mercury-197 chlormerodrin, and TRIGA reactor. The third part is devoted to the clinical aspects of tumor diagnosis. This book is of value to physicists, engineers, chemists, and clinicians.
