摘要
目的设计基于SMR170体模磁共振成像系统质量控制检测的线性度自动测量程序,实现线性度参数的自动测算。方法在Matlab平台设计编写了图像处理算法,对线性度参数进行自动测量,并采用Bland-Altman统计学方法对手工测量和自动测量两种方法的一致性进行了分析。结果利用Matlab平台设计编写的自动检测方法可实现线性度的自动检测,并且与手工测量方法有较好的一致性。结论线性度自动检测程序与手工测量可相互替代。
Objective To design an automatic linearity measurement program based on the quality control test of the SMR170 phantom MRI system in order to realize the automatic measurement of linearity parameters.Methods The image processing algorithm was designed and written on the Matlab platform,and the linearity parameters were automatically measured.The consistency between manual measurement method and automatic measurement method was analyzed by Bland-Altman statistical method.Results The automatic measurement program based on Matlab platform could measure linearity automatically,which had good consistency with manual measurement method.Conclusion The automatic linearity detection program and manual measurement can be substituted for each other.
