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.
