Few can be in any doubt about the enormous impact that radiology has made on the practice of medicine. Since their discovery by Konrad Roentgen in 1895, X-rays have become more and more involved in routine medical diagnosis from simple fractures through to the imaging of deep brain lesions by computed tomography. This book marks the centenary of the discovery of X-rays by describing the evolution of radiology in medicine, from the difficult and ultimately tragic experiments of Konrad Roentegen at the end of the 19th century to the high-technology computer-assisted equipment in widespread use today. It should be of interest not only to students of the history of medicine, but also to a radiologists wishing to learn more about the development of their subject and Roentgen's crucial role in it.
