SCOPE OF THE DOCUMENTThis document defines the minimum set of quality control (QC) tests to be applied to the [Manufacturer to enter commercial name of hardcopy device]@ a hardcopy output device that receives images from an FFDM system@ and reproduces them on [Manufacturer to enter description of hardcopy medium] for final interpretation. It should be considered as one element of the mammography facility??s Quality Assurance Plan.The tests in this manual generally focus on device constancy@ that is@ the ability of the hardcopy device to maintain its expected imaging performance over time. They do not address system quality control@ for example@ the ability of the various system components (image receptor@ acquisition workstation@ diagnostic workstations@ hardcopy output device) to communicate properly with each other@ and to use the communicated information correctly. Such system QC activities are assumed to have occurred during initial system installation@ initial system acceptance@ or as part of a Mammography Equipment Evaluation (see 4.11).
