阅片室内环境照度的检测与分析(英文)

Test and analysis of illuminance in reading room

目的参照DIN(多伊奇工业标准)6856等有关国际标准,对影响影像诊断质量因素之一的阅片室内环境(IRR)进行检测与分析。方法采用工业光度学测定方法,用风光牌ZF-2型照度计对山东省的省、地(市)、县三级医院共44个阅片室内的IRR进行检测,并进行统计学处理。结果(1)各级医院IRR普遍偏高,不合格率(按超过100LX计)45.45%;最严重者竟高达520lx,超过允许最大值(100lx)5倍多;(2)各级医院间IRR不合格率比较,无显著差异(X2=4.0813,P<0.05),即IRR的状况不因医院的升高而有所改善。(3)影像科室与非影像科室相比较,具有显著性差异(X2=4.0813,P<0.05),即非影像科室的IRR尤其不符合医学影像的诊断阅片要求。结论本检测结果表示:各级医院的IRR不合格率偏高,尤以影像科室为重,不符合现代医学影像的诊断阅片要求,难以保证诊断质量,亟待解决。

Objective ： To resereh one of the factors that influences the quality of photographic diagnosis - - - illuminance in reading room （IRR） according to the relevant international standard. Methods ： By the industrial optics testing methd , a test was made on IRR of 44 reading rooms in the hospitals of Shandong province with Illuminance - meter of Fengguang ZF - 2, and the data were statistically analyzed. Results （ 1 ） IRR in all the grades of hospitals was generally higher , and 45.5% of it was not in keeping with the standard, and the largest value was 520 lx, which was five times as large as the maxmum value which was avaluable. （2） Comparting the unqualified rate of IRR in all the grades of hospitals, we could see there was no noticeable difference（Х^2 = 0. 0387,P 〈 0. 05 ） ,that is to say,IRR couldnt be improved just because the grade of the hospital was higher. （ 3 ） Comparing the photographic department with the non - photogtaphic one , we could see there was noticeable difference（Х^2 = 4. 0813 ,P 〈 0.05 ） , that is to say, IRR in the non -photographic department especially did not meet the requirement of photographic diagnosis. Conclusion The results of the test show that the IRR in all the grades of hospitals is not in keeping with the standard,especially in the non -photographic department , and doesnt meet the photogtaphic diagnosis requirement of modem medical imaging. This cant guarantee the diagnosis quality,which must be solved at once.
