A type of radiography where the source of the X-rays is at a distance from the person being X-rayed.
A form of radiography in which the X-ray source is situated about 2 meters from the patient, which produces X-ray pictures with less distortion.
Radiography with the radiation source about 2 m (6F2 ft) from the body. Because the rays are virtually parallel at that distance, distortion is minimized.
