Average patient exposure for three diagnostic x-ray examinations

National surveys of over 600 facilities performing chest, lumbosacral spine, and abdominal examinations were conducted as a part of the nationwide evaluation of x-ray trends (NEXT) program. Radiation exposures were measured with use of a set of standard phantoms developed by the Center for Devices and Radiological Health. X-ray equipment parameters, film processing data, and data regarding techniques used were also collected. Results of these surveys are discussed. The average exposure values for these examinations are presented for use as guidelines in meeting some of the new Joint Commission on Accreditation of Healthcare Organizations requirements
