【Abstract】Objective To investigate the detection value of ACR motif in the
degree of homogeneity and thickness for MRI images,imProve the quality of MRI
s The degree of homogeneity and thickness of GE Excite HD 1.5T
and Siemens Skyra 3.0T nuclear magnetic resonance(MRI)images were detected by
ACR motif,the results were s The results of ACR motif detection
showed that the thickness of 1.5T MRI image was 5.6mm,the deviation of slice
thickness was 0.6mm,the degree of homogeneity was 93.1%；the thickness of 3.0T
MRI image was 4.6mm,the deviation of slice thickness was 0.4mm,the degree of
homogeneity was 96.2%.Conclusion Using ACR motif to detect the thickness and
the degree of uniformity for MRI images regularly can meet the required standards
for testing indicators,Ensure image compliance with clinical application
requirement,and improve the quality of MRI images.,It’s an effective method to
monitor the quality of MRI images.
