Title:
METHOD FOR MEASURING INTRINSIC TIME DOMAIN STABILITY PARAMETER OF RADIO FREQUENCY RECEIVING COIL IN FMRI
Document Type and Number:
WIPO Patent Application WO/2023/226115
Kind Code:
A1
Abstract:
A method for measuring an intrinsic time domain stability parameter of a radio frequency receiving coil in functional magnetic resonance imaging (FMRI), comprising: respectively inserting dielectrics having different thicknesses between the radio frequency receiving coil and a tested simulation phantom to change the distance between the coil and the phantom, so as to simulate the relative motion between the coil and the phantom (S101); acquiring a plurality of echo EPI images of the tested simulation phantom when the dielectrics having different thicknesses are inserted, and performing processing and reconstruction to obtain intrinsic imaging data (S102); and calculating according to the intrinsic imaging data to obtain an intrinsic time domain stability parameter of the coil (S103). All complex physiological noises possibly existing in functional magnetic resonance acquisition can be eliminated, and only time domain noises caused by relative motion between the radio frequency receiving coil and the tested phantom are considered; and the acquired intrinsic time domain stability parameter can be used for guiding design and use of a special radio frequency receiving coil in an FMRI application, and improving the image performance of FMRI.
