• Description:
  Technical problems and techniques for obtaining accurate chest X- rays were discussed. Instrumental parameters required for obtaining chest X-rays for pneumoconiosis were summarized. It was noted that since the enactment of public law 91-173 which states that every coal miner shall have the opportunity to have a chest X-ray examination for the purpose of establishing health and safety standards, new interest has been generated in techniques for obtaining chest X-rays. The scattered radiation problem was discussed. Scattered radiation can damage portions of a radiographic image. In a nongrid chest image up to 65% of the radiation reaching the screen or film can be scattered. Nongrid chest X-rays are usually made with 85 kilovolt (kV) X-rays. Modern chest X-ray examinations utilize high ratio grids with high voltages, on the order of 110 to 150kV. Problems associated with grid radiography and solutions were discussed. Obtaining information on the mediastinum during chest X-ray examinations was considered. Utilizing three phase voltages and automatic exposure control during chest X-ray examinations was discussed. Problems associated with collimators were summarized.
