ABSTRACT
Essential Purchase – Doody’s Core Titles 2022
This second updated edition of the Encyclopaedia of Medical Physics contains over 3300 cross-referenced entries related to medical physics and associated technologies. The materials are supported by over 1300 figures and diagrams. The Encyclopaedia also includes over 600 synonyms, abbreviations and other linked entries.
Featuring over 100 contributors who are specialists in their respective areas, the encyclopaedia describes new and existing methods and equipment in medical physics. This all-encompassing reference covers the key areas of x-ray diagnostic radiology, magnetic resonance imaging (MRI), nuclear medicine, ultrasound imaging, radiotherapy, radiation protection (both ionising and non-ionising) as well as related general terms.
It has been updated throughout to include the newest technologies and developments in the field, such as proton radiotherapy, phase contrast imaging, multi-detector computed tomography, 3D/4D imaging, new clinical applications of various imaging modalities, and the relevant regulations regarding radiation protection and management.
Features:
- Contains over 3300 entries with accompanying diagrams, images, formulas, further reading, and examples
- Covers both the classical and newest elements in medical imaging, radiotherapy, and radiation protection
- Discusses material at a level accessible to graduate and postgraduate students in medical physics and related disciplines as well as medical specialists and researchers
