Abstract:
Objective:To explore the calibration method of quality detection of spectrum therapy instrument in low pressure environment,so as to ensure its safety and stability in clinical use.Methods:Aimed at the 4 types of vertical spectrum therapy instrument,the calibration of quality test were carried out in normal environment and the simulated low pressure environment for 5 different altitudes that included 1.0,2.5,3.5,4.5 and 5.5 km.The detection of appearance function,unevenness of surface temperature and surface error,as well as the repetition of measurement of spectrum therapy instrument among different low pressure environment were compared.Results:In the low pressure environments of 5 different altitudes,the performance parameters of 3 types of spectrum therapy instruments were better,and the error of temperature unevenness was less than 10％.The performance of one type of spectrum therapy instrument was poor,and the error of temperature unevenness was between 10％and 20％.For the error of surface temperature of radiator,one type of spectrum therapy instrument was＜10％,and one type of that was＞15％,and two types of that cannot be assessed because there was not specific value.In normal environment,each detection indicator of 4 spectrum therapy instruments were normal.In this trial,the repetition of the result of only 1 type of spectrum therapy instrument was relatively larger,which was between 1.5％and 2.4％,and the repetition of other types was smaller.Conclusion:The calibration and detection methods of quality test of spectrum therapy instrument was explored in this article,which can ensure the clinical therapeutic effect,safety and stability.It is helpful to reduce the risk of that in clinical use.
