The radiographer fills an important role in the diagnosis and treatment of disease by assisting radiologists and producing images that visualize and record human anatomy. Radiologists are physicians who specialize in the use of x-rays to diagnosis and treat disease and traumatic injury. Radiographers perform x-ray examinations of the skeletal, respiratory, circulatory, nervous and digestive systems--- using their knowledge of patient care, biological effects of radiation, radiation protection, anatomy, physiology, physics, positioning and radiographic technique. While performing radiographic procedures, they assess and care for patients, interact with physicians and other health professionals and communicate with patients, families and the general public. A radiographer should possess such personal attributes as compassion, competence and concern for meeting the specific needs of the patient.
