From the Watching of Shadows: The Origins of Radiological Tomography presents the first complete history of body imaging by discrete sections, from its earliest beginnings around 1920 to modern times. Divided into two parts, the book is highly illustrated with many original figures from patents and some previously unpublished pictures. The first part covers classical tomography from 1920 to the 1960s, including the origins of radiological tomography. The second part takes a fresh look at computed transmission and emission tomography that includes recent developments by pioneering tomographers. Tables in each chapter summarize key historical landmarks. The book also includes an extensive glossary of technical terms and a comprehensive index. It is ideal reading for diagnostic radiologists and radiographers interested in the origins of their techniques, for practicing medical physicists, and for historians of medicine and science.
