Daily inspection
As requested by the local procedures for mammography and Organisation for
Quality Control for mammography, check the equipment on a regular basis to
be sure that workflow and image quality can be guaranteed.
1. Check the environment
Check to make sure temperature and humidity are within normal
operational range.
2. Check the cables
a) Ensure that cables are not damaged and cable jackets are not torn.
b) Check that the plugs, locks and connectors are fully inserted.
c) Check that the covers of all components are not damaged and tightly
fixed.
3. Check the detector
a) Ensure that there are no loose screws or breaks.
4. Start the NX workstation.
5. Start the DR detector.
The detector will automatically run a series of self-tests. The orange and
green led lights next to the network connector are lit to indicate that the
control unit is connected to the NX workstation. The three led lights are lit
to indicate that the self-tests have been passed.
6. Perform a test exposure.
Local procedures for mammography or the local Organisation for Quality
Control for mammography can advise to expose a certain QC phantom.
Follow their instructions and select the dedicated technical exam type on
the NX workstation ("System Diagnosis Mammo").
Alternatively a typical flat field exposure is made after selecting the
dedicated technical exam type on the NX workstation ("System Diagnosis
Mammo"). Compress the standard PMMA block and expose with the
automatic settings. The alternative manual exposure settings can be 28kV
- between 60 to 70 mAs - MoMo.
7. Check the displayed image for image distortion or indications of data loss
or image defects.
If there is any problem found during the inspection, contact your local service
representative.
