The National Electrical Manufacturers Association (NEMA) has published four test standards developed by the medical diagnostic imaging industry for the measurement of performance parameters that govern image quality of MRI systems.
According to the Rosslyn, VA-based industry group, the MS 4-2006 test standard, "Acoustic Noise Measurement Procedure for Diagnostic Magnetic Resonance Imaging Devices," has been revised. The new test standards include:
- MS 10-2006, Determination of Local Specific Absorption Rate (SAR) in Diagnostic Magnetic Resonance Imaging
- MS 11-2006, Determination of Gradient-Induced Electric Fields in Diagnostic Magnetic Resonance Imaging
- MS 12-2006, Quantification and Mapping of Geometric Distortion for Special Applications
The test standards are intended for use by equipment manufacturers, testing houses, prospective purchasers, and MRI users, NEMA said.
