An Integrated Signal-to-Noise Ratio Approach for Phased-Array Coil Health Check
Guclu C, Huff S
As the number of channels increases on commercial MRI scanners, it is getting more difficult to identify individual coil element failures, and collecting reliable SNR data. The purpose of this study was (i) to design an automated software tool with appropriate protocols to identify element failures in a multi-coil array (a.k.a Phased-Array Coil), (ii) to make the method immune to other internal and external disturbances, i.e. improving the gage repeatability and reproducibility.
