An Assortment Of Image Quality Indexes For Radiographic Film-Screen Combinations ---Can They Be Resolved?

The following briefly summarizes the background on how the Bureau of Radiological Health became involved in the image analysis area. In October 1968 the Radiation Control for Health and Safety Act, Public Law 90-602, gave the Secretary of the Department of Health, Education, and Welfare and by delega-tion to the Food and Drug Administration new functions involving the radiation safety responsibility to control ionizing and nonionizing radiation emitted from electronic products. A majority of the responsibilities under the law have been redelegated to the Bureau of Radiological Health.
