摘　　要：目的:探索频谱治疗仪在低气压环境中的质量检测校准方法,以确保其临床使用的安全性和稳定性。方法:针对不同型号的4台立式频谱治疗仪,选择正常环境和模拟1.0、2.5、3.5、4.5和5.5 km的5个不同海拔高度的低气压环境进行质量检测校准,对比分析不同低气压环境中频谱治疗仪的外观功能检测、表面温度不均度和表面误差以及测量重复性误差。结果:在5个不同海拔高度的低气压环境中,有3台不同型号频谱治疗仪性能参数较好,温度不均匀度的误差<10%,有1台频谱治疗仪性能较差,温度不均匀度的误差为10%~20%。辐射器表面温度误差检测中1个型号频谱治疗仪<10%,1个型号>15%、2个型号无具体值无法评估。在正常环境中4个不同型号频谱治疗仪的各项检测指标均正常,而在本次试验中仅1个型号的频谱治疗仪的测量结果重复性相对较大,为1.5%~2.4%,其余3个型号的重复性较小。结论:探究频谱治疗仪进行质量检测校准和检测方法,可保证临床的治疗效果及其安全性与稳定性,有利于降低临床使用风险。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.
