We are sending our densitometer out for a regularly scheduled calibration. While it is gone, how can we continue with our daily quality control program until it is returned? Can we use a "loaner" densitometer or perform some substitute test in the interim?

The daily processor quality control is required prior to processing patient films. No alternative is currently available to verify processor performance without a densitometer. If your facility plans to use a loaner densitometer, reintroduce one into service after repair/calibration, or obtains a new densitometer, you should contact your medical physicist for instructions on how to proceed.
