The American Osteopathic College of Radiology (AOCR) is a not-for-profit organization established in 1941 as the principal organization serving osteopathic radiologists. The AOCR is committed to advancing the practice of radiology by promoting excellence in education, research and the delivery of quality, cost-effective healthcare while embracing the tenets of osteopathic medicine. The society seeks to foster closer solidarity and greater cooperation among radiologists, other branches of medicine and allied healthcare professionals. The AOCR is an affiliate organization of the American Osteopathic Association (AOA) and represents over 900 members.

Formal radiology residency training began in the osteopathic profession in the early 1930s at the Philadelphia Osteopathic Hospital. The first x-ray equipment in the osteopathic profession was installed in 1898 in the A. T. Still Infirmary at the American School of Osteopathy, then in its sixth year in Kirksville, Missouri. David Littlejohn, Ph.D., M.D., the profession's first true radiologist, was the first faculty member to teach radiology-then called x-radiance-in an osteopathic medical school. After earning the D.O. degree at Kirksville, Littlejohn left ASO and established the American College of Osteopathic Medicine and Surgery, now Chicago College of Osteopathic Medicine of the Midwestern University. In concert with the rapid advances in technology, residency training has strengthened over the years. New modalities and imaging techniques made a longer training program imperative and the four-year diagnostic radiology training program became mandatory in 1989. A four-year program in radiation oncology also became mandatory in 1998.

Professional education was a primary purpose of the founding of the AOCR. As both an AOA and an Accreditation Council for Continuing Medical Education (ACCME) accredited sponsor, the AOCR sponsors two continuing medical education activities each year.

The college has progressed from a scientific and educational organization to a broader role that includes socioeconomic issues and a political aspect. The American Osteopathic College of Radiology Education Foundation, Inc., was established in 1986 as a not-for-profit organization devoted to the dissemination of accurate and useful information to the general public concerning radiology and health care and to support the educational endeavors of the AOCR. The AOCR has provided strong leadership in ensuring quality in healthcare. An association newsletter is published quarterly and a report on current legislative activity in Washington is published as important issues occur. The College reviews and endorses standards of practice developed by radiological organizations. A recruitment and placement service is also offered.
