An Australian perspective on chiropractic spinography.

Daniel David Palmer and Wilhelm Conrad Roentgen were born in the same year, and each of them, at the age of fifty, made the discovery for which he came to be best known. Both of them built upon earlier theories and discoveries. Roentgen's discovery, x-ray, was to become an indispensable diagnostic tool for the profession which grew out of Palmer's discovery, chiropractic. This paper traces some of the developments which led to the discovery of x-ray, early milestones in applied radiography, and the emergence of spinography in chiropractic. Special emphasis is given to chiropractic innovations in roentgenography and the use of spinography by chiropractors practising in Australia.
