I have been following the ACR manual and have used an optical density range of 0.7-0.8 when doing my screen-film contact test. The film manufacturer recommends that I use a higher optical density. What should I use under the final regulations?

The final regulations do not reference a specific manual giving facilities flexibility to use procedures that best enable them to meet the requirements. In this specific case, the facility may follow the manufacturer’s recommendation, their medical physicist’s recommendation, or an appropriate manual in performing the screen-film contact test or any other QC test.
