A brief historical review of the discovery of X-ray by Wilhelm Konrad Roentgen on November 9, 1895, is presented. This synopsis discusses the evolution of X-ray imaging from the primitive Crookes x-ray tube to the state-of-the-art high-frequency generators. Technological advancements from fluoroscopy to plain films, nuclear medicine, computed tomography and magnetic resonance imaging, along with changes in X-ray film and intensifying screens, are also provided. A concise overview of chiropractic radiology and the introduction of X-ray into the chiropractic curriculum, first at Palmer College and then at other colleges is presented. Historical recognition of the development of the American Chiropractic Board of Radiology (ACBR), its founding fathers and its certification program for training chiropractic radiologists is reviewed. General comments pointing to computerized digital imaging as the filmless imaging of the future are offered.
