transported. The FSE told the tech other testing is required per the manual, but I can’t locate it the manual and he wasn’t able to give me the section in the user manual referencing that requirement or the tests that are required. This causes the tech to
pretty much refuse to use the unit, even when the sites leadership told her I did the full annual testing on the unit. I did a full test on the C-arm the other day and my measurements were almost identical to when I tested it in March.<u></u><u></u></span></p>

<p class="MsoNormal">For those unaware, a phantom, likely a metal plate, is imaged, and the kV amd mA must be within a certain range, given by a dose ratio calculation against a baseline (i.e. kV^2 * mA). For those who don't want to do a clunky calculation,
the units report dose rate. The idea is for the dose rate to be within 25% of a baseline.<u></u><u></u></p>
