QA BEAMCHECKER™ PLUS 13
4. Exit the vault and use the patient monitor and monitor to view the front of the QA
BeamChecker Plus display.
Orientation may differ depending on room type or energy selected
Delivery
5. Expose the QA BeamChecker Plus with the desired energy. During the exposure, the QA
BeamChecker Plus front display will show as spinning lines indicating a signal has been
detected and measurement is in progress. After the exposure has ended, a single “beep”
sound will occur, and an energy designation will show on the front display if it was successfully
recognized. For example, 10X (10 MV photons). If the exposure falls within allowed action levels
(tolerances) configured during the baseline – i.e. PASS, the QA BeamChecker Plus will
automatically save the details for this measurement, reset and display RdY after about 10
seconds. It is now ready for the next energy exposure.
NOTE: If QA BeamChecker Plus has determined the energy falls outside of allowed action
levels – i.e. FAIL, a repeated “beep” sound will occur and one or more of the following
messages will appear on the front display: CST (Constancy), FLT (Flatness), ASM (Axial
Symmetry), TSM (Transverse Symmetry). The speed and pattern of the beeping sound will
differ depending on whether the measurement falls outside of action level 1 or 2. At this point,
the treatment vault must be entered and the QA BeamChecker Plus manually reset by
pressing the RESET/ROOM SELECT button. The details for this measurement will be saved for
later investigation, and the QA BeamChecker Plus will display RdY. At this point, the failed
energy can be attempted again, or a different energy can be tried.
6. Repeat the step 5 for all desired energies. If switching between photon and electron
measurements, enter the vault to flip the device to the appropriate side and press the MODE /
PLAN button. All measurements (pass or fail) will be saved for further review.
Measurement data is now ready to be downloaded by the PC for analysis and trending. Up to
512 unique measurements can be stored before download is required, but it is good practice
to download data once every week to ensure the Wire-Free mode-acquired measurements
are saved in the database..
