摘　　要：目的:研究一种用于脑部电阻抗成像数据回放分析的干扰预处理算法。方法:通过对脑部电阻抗图像监护数据进行统计学分析,计算标准差,从而检测干扰,并通过引入偏置量的方法对其进行滤除。结果:临床实验数据结果表明该算法可以在数据回放分析过程中有效滤除干扰的影响。结论:该方法是一种速度快、效果好的干扰预处理方法,可以很好地辅助大量临床数据的分析工作,为脑部电阻抗图像监护的临床深入研究打下基础。ObjectiveTo develop an artifact pre-processing method for data playback analysis of brain electrical impedance tomography. Methods The standard deviation of brain electrical impedance tomography data was calculated to detect the artifact, which was then reduced by subtracting an offset. Results The clinical results showed that the method could effectively reduce the artifact during data playback analysis of brain electrical impedance tomography.Conchuslon The method is fast and effective for artifact reduction, which can facilitate further clinical experimental data analysis.
