The importance of the right focusing technique. At-a-glance information on focusing techniques in X-ray procedures

Sharp pictures providing all the information relevant to a particular case obviate repeat exposures, help to keep the radiation dose to a minimum and prevent false diagnoses. In her book, the author gives practical guidance on focusing techniques that is equally valuable to beginners and experienced investigators or medical X-ray assistants and physicians. A substantial part of the book is devoted to detailed instructions on how an object is brought into focus as well as on the criteria of proper focusing and the possibilities of identifying and avoiding false focusing techniques. The problems arising when uncommon X-ray pictures have to be taken are explained by diagrammatic representations. (orig.)
