Radiation Detectors For Medical Applications

The topic of this book is the use of scintillating materials in the detection of ionising radiation for medical imaging. The text surveys the state of the art in radiation detectors for medical imaging, followed by an in-depth review of all aspects of the use of scintillating materials. Also included are detailed discussion of ways to improve the performance of existing scintillating materials and completely novel uses of scintillating materials.

Ionizing Radiation Detectors for Medical Imaging contains ten technical chapters, half of which are devoted to radiology and the other half to nuclear medicine. The last chapter describes the detectors for radiotherapy and portal imaging. Each chapter addresses completely a specific application. The emphasis is always on detector fundamentals and detector properties. Where necessary, software and specific applications are described in depth. This book is intended for graduate and undergraduate students in physics and engineering who want to study medical imaging. In addition, scientists who are working in a specific sub-field of medical imaging can acquire from the book an up-to-date description of the state of the art in related sub-fields, within the scope of ionizing radiation detectors. Other scientists, as well as physicians, can use the book as a reference for medical imaging.
