Vibro-acoustic spectral analysis of low-field MRI

Arawade Swapnil, Piechowicz Janusz, Pałasz Tadeusz

International Journal of Electronics and Telecommunications

2025

Vol. 71, No. 4

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.

Komputerowe wspomaganie przy tworzeniu 3D obiektów anatomicznych

The paper presents the method of reconstruction of anatomical objects. Magnetic Resonance Imaging (MRI) is one of the most common imaging modalities in which internal body structure is viewed non-invasively. For rendering of MR images, we took an approach that was introduced by Cline in 1987 called the Marching Cubes 3D.
