INFLUENCE OF PERSON WEIGHT ON SPECTRAL PROPERTIES OF ACOUSTIC NOISE IN THE OPEN-AIR MRI

J. Přibil, A. Přibilová, I. Frollo

Abstract

The paper analyses the change in spectral properties of an acoustical noise when the examined person lies in the scanning area of the open-air magnetic resonance imager (MRI) so that the holder of the lower gradient coils is loaded with his/her weight. Obtained results of spectral analysis will be used for design of a correction filter to suppress the noise in simultaneously recorded speech signal for 3D modelling of the human vocal tract.
