NEMA MS 6:2008 (R2014)

This standards publication defines test methods for measuring the signal-to-noise ratio and image uniformity of MR images produced using special purpose single-channel non-volume coils or a single channel of an array coil.. ('surface coils'). These methods are applicable to both receive-only and transmit-receive RF coils. This document does not address the use of general head and body coils, special purpose single-channel volume coils (see MS 1 and MS 3), or analysis of data from coils that require multiple receiver channels for operation (array coils, see MS 9).
