National Electrical Manufacturers Association (NEMA) published NEMA MS 14-2019 Characterization
of Radiofrequency (RF) Coil Heating in Magnetic Resonance Imaging
Systems. This new Standard measures the radiofrequency coil surface temperature
increase induced by the radiofrequency fields in magnetic resonance imaging.
Testing methods are provided for detachable RF receive coils, detachable
transmit/receive coils, and integrated body coils.
“This Standard provides an MRI-specific methodology for surface temperature measurements
that helps to ensure patient safety as required by IEC 60601-1 and other Standards,”
said Michael Steckner, Chair of the MR Technical Committee and Senior Manager
at Canon Medical Research. “This method is also useful for research groups who
build their own coils,” added Dan Spence, Principal Engineer at GE
benefit from this Standard are in the health care industry who work with medical
imaging and radiology, as well as the patients receiving magnetic resonance
