Organization: NEMA
Publication Date: 1 January 2010
Status: active
Page Count: 22
scope:

The purpose of this NEMA Standards Publication is to provide methods to determine the acoustic noise level of an MR system. Two measurement procedures are defined, Maximum Gradient Acoustic Noise (MGAN) and Maximum Clinical Acoustic Noise (MCAN).

This procedure has been designed for measuring peak sound pressure levels (SPL) up to 140 dB. Above 140 dB, the use of more sophisticated equipment and methods may be required.
