First published in 1939, this is the definitive text on patient positioning for the diagnostic radiography student and practitioner. The experienced author team appreciates that there is no substitute for a good understanding of basic skills in patient positioning and an accurate knowledge of anatomy to ensure good radiographic practice. This 12th edition retains the book’s pre-eminence in the field, with hundreds of positioning photographs and explanatory line diagrams, a clearly defined and easy-to-follow structure, and international applicability. The book presents the essentials of radiographic techniques in a practical way, avoiding unnecessary technical complexity and ensuring that the student and practitioner can find quickly the information that they require regarding particular positions. All the standard positioning is included, accompanied by supplementary positions where relevant and illustrations of pathology where appropriate. Common errors in positioning are also discussed.
