4.2 Testing with Built-in Photometer Sensor Displays
For built-in photometer sensor displays, QAWeb automatically runs the Hologic
Compliance Test once per week and the Auto-calibration routine twice per year. Use this
procedure as follows:
• Radiologic Technologist: Verify that the test(s) ran successfully.
• Medical Physicist: Review and record the numerical results from the most recent
Hologic Compliance Test.
Note
Hologic recommends for displays older than five years that the Medical Physicist use
an external photometer once per year for the luminance check to confirm that the
internal photometer is still operating correctly. The luminance measured by the
photometer must be within 15% of the calibrated luminance. The calibrated luminance
for each display can be found in the configuration of QAWeb Agent or in the most
recent compliance check results in the status.
4.3 Testing with External Photometer Sensor Displays
For external photometer sensor displays, MediCal QAWeb alerts you to run the Hologic
Compliance Test once per week and the Auto-calibration procedure (refer to section
Manually Calibrating Displays on page 31
) twice per year. Use the procedure in this section
as follows:
• Radiologic Technologist: Run the QC tests and verify that they ran successfully.
• Medical Physicist: Review and record the numerical results from the most recent
Hologic Compliance Test.
To run the tests and calibrate the displays, users must have an external photometer as
shown in the following figures.
