Vibro-Acoustic Spectral Analysis of Low-Field MRI
Abstract
Magnetic Resonance Imaging (MRI) is modern diagnostic tool to obtain internal images of human body. Vibration and noise are major challenges inherited by the MRI since their development. The paper analyses vibration and sound signals produced from the Low-field MRI system for different scanning sequences. Results from spectral analysis revealed strong relation between the vibration and sound signal, showing scanning sequence specific peaks at multiple frequencies. The results are useful to understand the dynamic nature of vibration and sound signal from MRI to develop the attenuation strategy.
