I welcome this book on behalf of radiographic practitioners every­ where. It arrives at a time of rapid change within the world of medical imaging where advancing technology and changes in employment conditions are having a major effect on the everyday working practices of those who physically and clinically direct radiation. The development of radiography as a graduate profession within the United Kingdom provides the opportunity for role extension and role fulfilment for radiographers. Moves toward standardized quality assurance and quality control programmes in radiography and radi­ ology include not only the audit of equipment but also working practices. The science and art of image production form the corner­ stone for these working practices where radiographic skills and image quality lead to the provision of a caring, quality service. This book will help the development and continuation of this programme by affording detailed information on a wide range of imaging procedures for radiographers, including positioning and procedural protocols, as well as image acceptance criteria. A major feature of this book is the systematic chronological presentation of its content which makes it a boon to both the new and experienced practitioner as well as those studying for a radiography degree or involved in the first year of the FRCR examination. Elizabeth Unett and Amanda Royle are experienced radiographers and educationists in imaging sciences. They have both played a major role in the development of clinical education programmes for diploma and undergraduate radiography students.
