We have FFDM units from different manufacturers, each with its own QC manual. The manuals have different recommendations for QC testing of our printers and monitors. What QC testing should we perform on our printers and monitors?

Policy Guidance Help System logo

For facilities that are using FFDM units from different manufacturers, each with its own QC requirements for printers and monitors, there may be uncertainty regarding which QC tests must be performed on these components. The following three examples should help facilities decide.

a. Each FFDM manufacturer’s QC manual requires that the same test be done, but at different time frequencies. In this case facilities should perform the test at the more stringent frequency.

b. Each FFDM manufacturer’s QC manual requires that different but equivalent tests be done. In this case facilities may perform only one of the tests at the more stringent frequency. The medical physicist should provide a written statement for the facility’s quality control records, indicating that, in his or her opinion, the two tests are equivalent.

c.Each FFDM manufacturer’s QC manual requires that different tests (not equivalent) be done. In this case facilities should perform each test at the frequency required in the respective FFDM manufacturer’s QC manual.
