7 Routine QA Measurements
7.1 Introduction
After baseline acquisition has been completed for the desired plans and energies by following
the instructions in the Preparatory Measurements - Baselines section of this manual, the QA
BeamChecker Plus is ready for routine measurements.
NOTE: It is recommended to perform routine measurements during the same part of the day
that the baseline was acquired. While the on-board temperature and pressure sensor can
compensate for some changes in environmental conditions, other factors such as the state of
accelerator warm-up and repeatability of couch placement can produce false positives for
faults in beam quality. Consistency is important to make an accurate relative comparison
measurement.
The QA BeamChecker Plus offers two distinct modes for performing routine measurements:
Wire-Free Mode and Real-Time Operation Mode. Both modes ultimately record identical,
comprehensive measurement information, but differ in setup and the level of detail presented
at time of measurement. Read on to learn about the benefits of each mode.
About Wire-Free Mode

The Wire-Free Mode provides the fastest method for performing routine QA measurements
for a linear accelerator by providing an easy, software-free solution for identifying if an energy
or plan is out of tolerance. After creating baselines, the QA BeamChecker Plus is equipped
with all the information necessary to perform automatic energy detection and relative
comparison - all without being tethered to a computer. Set the QA BeamChecker Plus on the
treatment couch, expose it to the beam with any baselined energy, and the front panel display
