The American Association of Physicists in Medicine (AAPM) is a scientific and professional organization founded in 1958. AAPM is based in Alexandria, VA. The organization is composed of more than 8,000 scientists whose clinical practice is dedicated to ensuring accuracy, safety, and quality in the use of radiation in medical procedures such as medical imaging and radiation therapy. AAPM is generally known as medical physicists and is uniquely positioned across medical specialties due to their responsibility to connect the physician to the patient through the use of radiation-producing technology in both diagnosing and treating people. The responsibility of the medical physicist is to assure that the radiation prescribed in imaging and radiation therapy is delivered accurately and safely.

American Medical Association engages in promoting the art and science of medicine and the betterment of public health. It offers services to physicians, residents, medical students, and patients. The company was founded by Nathan Smith Davis in 1847 and is headquartered in Chicago, IL.
