Summary

This book provides comprehensive and easy-to-follow coverage of the principles and application of physics for both diagnostic and therapeutic radiography students. Regardless of changes in technology and clinical grading, the most important role of the radiographer remains unchanged - ensuring the production of high quality images and optimal treatment. These should be performed with the minimum of radiation hazard to the patient, the radiographers themselves and others whose presence is a necessary part of the examination or treatment. An understanding of physics and the basics of radiographic technology is essential to do this effectively. The book covers all the physics and mathematics required by undergraduate diagnostic and therapeutic radiography students studying for a BSc (Hons), catering for those who do not have A-level mathematics as well as for those who do. This edition focusses more upon application of physics than pure physics, reflecting current teaching approaches. This has resulted in a major overhaul of the book onto two parts - Principles and Application. The new edition#xA0;has an updated 2-colour design and new Sections on Equipment for X-ray production, The Radiographic Image and Diagnostic Imaging Technologies. The textbook is supported by electronic learning resources for students, hosted on EVOLVE. Student resources Self-assessment questions *Strong links between theory and practice throughout *Clear and concise text Focus on application of physics, as well as principles New, updated 2-colour design New Sections - Equipment for X-ray production, The Radiographic Image and Diagnostic Imaging Technologies Electronic learning resources for students support the text
