HIGHLIGHTS
SUMMARY
Gradient coils of magnetic_resonance imaging (MRI) scanners undergo large Lorentz forces as rapidly switched electrical currents are passing through them in the presence of the static magnetic_field B0. Due to these forces, the gradient coil conductors vibrate, and these vibrations radiate into the air as acoustic pressure waves and sound radiation. Accurate numerical modeling of gradient coil acoustics is essential for realistic noise estimates and safety analysis. July 2022 | Volume 10 | Article 907619 Noise Reduction in MRI Gradient Coils Mechefske et_al performed the first FEM numerical modeling of gradient coil acoustics, where both vibrational . . .
