Raktažodžiai:

The second edition of this easy-to-understand pocket guide remains an invaluable tool for students, assistant practitioners and radiographers. Providing an accessible introduction to the subject in a reader-friendly format, it includes diagrams and photographs to support the text. Each chapter provides clear learning objectives and a series of MCQs to test reader assimilation of the material.

The book opens with overviews of image production, basic mathematics and imaging physics, followed by detailed chapters on the physics relevant to producing diagnostic images using X-rays and digital technologies. The content has been updated throughout and includes a new chapter on CT imaging and additional material on radioactivity, dosimetry, and imaging display and manipulation.

Clark’s Essential Physics in Imaging for Radiographers

supports students in demonstrating an understanding of the fundamental definitions of physics applied to radiography … all you need to know to pass your exams!

Ken Holmes is now retired but was the programme leader for the BSc (Hons) Diagnostic Imaging at the University of Cumbria (formerly St Martins College). He is one of the co-authors of Clarks Pocket Handbook for Radiographers and believes the time is right to develop a pocket physics book to use alongside the technique one. Ken started education as a clinical tutor and has worked at several higher education institutes in the UK and has taught physics and imaging principles for 30 years.

Marcus Elkington is a senior lecturer in Diagnostic Imaging at Sheffield Hallam University. He has a great interest in imaging and physics related to diagnostic radiography and has been helping students understand physics for many years. Marcus feels there is a place for a pocket physics book produced in a student-friendly format that is aimed specifically at the core topic areas surrounding general radiographic imaging.

Phil Harris was head of school at Medical Imaging Science at the University of Cumbria for many years and has always taken the greatest pleasure in passing on a basic understanding of radiation science to radiography students, many of whom enter into this subject with some considerable trepidation. This book has been written especially with these students in mind.
