Excerpt from The Principles of Radiography
The book contains little or nothing that an experienced X-ray worker will not have had to discover for himself during the course of his work. The discovery of physical principles with the aid of an elaborate X-ray installation is, however, apt to be an expensive as well as a tedious process, and the ordinary text-books of Physics are not primarily concerned with the needs of radiographers. It seemed, therefore, that practitioners and others who might be commencing this fascinating branch of work with no greater knowledge of physics than some hazy recollections of a first M.B. examination, might welcome a brief explanation of the principles of the subject on the physical side. With the medical side of the subject it is not within my province to deal.
The subject-matter of this volume formed part of a series of lectures given in connection with the recently established Diploma in Medical Radiology and Electrology, at Cambridge. The interest shown by the members of the class in the physical principles of the subject, and the difficulty experienced in finding any book which met our immediate requirements, encourages me to hope that these pages may prove of use to a wider circle.
