国产、进口CT硬件参数与性能研究

Comparative Study on Domestic and Imported CT Hardware Parameters and Performance

目的探讨某地区在用国产、进口CT设备的性能及优劣。方法收集汇总15类检测参数,利用SAS9.4软件进行统计分析。结果12类参数差异无统计学意义,3类参数差异有统计学意义。结论国产CT与进口CT性能参数水平相当。

Objective To explore the performance,advantages and disadvantages of domestic and imported CT equipment in use in a certain area.Methods 15 types of detection parameters were collected and summarized,and analyzed by SAS 9.4 software.Results There was no statistically significant difference in 12 types of parameters,and the difference in 3 types of parameters was statistically significant.Conclusion The performance parameter level of domestic CT is equivalent to that of imported CT.
