The early history of x-ray diagnosis with emphasis on the contributions of physics 1895-1915.
The contribution of physics to the development of x-ray diagnosis was vital in the early years of this century following Röntgen's discovery of x-rays in November 1895. This review records some of the highlights during the period 1895-1915. Much of the information presented has been buried in libraries for more than 50 years and the selection of illustrations and text will be largely unknown to today's readership of Physics in Medicine and Biology. It is also a celebration of what could be achieved in physics before the occurrence of the technological revolution involving not only computer applications but also the disappearance of the small independent x-ray companies into today's multinational companies. Research and development is nowadays just too expensive for much independent practical high-technology contributions without financial backing. Hence this review takes us to those bygone years of experimental physics in home laboratories, poorly equipped university physics laboratories and of the lecture-demonstrations of the period. The sections are presented in a logical order beginning with the discovery of x-rays, followed by x-ray tube technology to the advent of the hot cathode Coolidge tube, with the third and final section covering diagnostic radiology physics. It has been compiled from personal research over 35 years in libraries worldwide, drawing on textbooks, journals, popular magazines, newspapers, x-ray company catalogues and museum exhibits. I have included a certain amount of anecdotal information, because after all, much of the early commentaries were indeed anecdotal--and make very interesting reading. Finally it is commented that although this review is devoted to x-ray diagnosis, x-ray therapy should not be forgotten, and readers are referred to another review by the author on early therapeutic advances.
