900.12(b)(14): Lighting. The facility shall make special lights for film illumination, i.e., hot-lights, capable of producing light levels greater than that provided by the viewbox, available to the interpreting physicians.

  1. Are there any specific requirements concerning the viewing conditions for screen-film mammograms?
  2. Are there any regulations regarding viewbox luminance?
  3. Our mammography exams are interpreted off-site. Do we need to have a viewbox, hot light, and masking materials on-site?
  4. Do masking view-scopes meet the masking requirement, even if their field of view is smaller than that of the size of the film?
