Electromagnetic Noise Characterization and Suppression in Low‐Field MRI Systems

Magnetic Resonance in Medicine, Volume 95, Issue 5, Page 3000-3007, May 2026.
ABSTRACT Purpose Our goal is to develop and validate a practical protocol that guides users in identifying and suppressing electromagnetic noise in low‐field MRI systems, enabling operation near the thermal noise limit. Methods We present a systematic, stepwise methodology that includes diagnostic measurements, hardware isolation strategies, and good ...
