Abstract:Objective To compare the atmospheric pressure acquired by SNC Daily QA3 with that by
barometer and assess the accuracy of pressure value recording by Daily QA3. Methods We selected
the measured value of atmospheric pressure around the accelerator acquired by barometer and Daily
QA3 at weekly inspection between June 2014 and December 2015, then compared and analyzed the
data. Results The value acquired by Daily QA3 is corresponding to that measured by barometer. The
difference between the two values is within ±0.5 kPa. Conclusion The precision of atmospheric
pressure value given by Daily QA3 is high and it can provide reference for the pressure measurement of
radiotherapy.
