使用Daily QA3晨检仪测量气压值的应用分析
ApplicationAnalysis on Measurement ofAtmospheric Pressure Using Daily QA3
摘要
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.关键词
