NEMA revises MRI test methods

The National Electrical Manufacturers Association (NEMA) has revised its test methods for measuring absolute spatial variation as it relates to the geometric accuracy within MR images.

NEMA's publication, NEMA MS 12-2016: "Quantification and Mapping of Geometric Distortion for Special Applications," details the specifications as a map, graph, or table throughout the imaging region rather than as an average or worst-case error.

The revisions also consider an increased variety of test materials, covering medical imaging, radiology, and conformity assessment industries.

NEMA MS 12-2016 is available in hard-copy form for $72 or as an electronic download for no cost on the NEMA website.
