Patent ID: 7502526

Claim:
A method for filtering time-varying magnetic resonance (MR) signal data comprising: Using a processor to perform the steps of: receiving the time-varying magnetic resonance (MR) signal data indicative of an image of an object; performing for a plurality of different time instances of the time-varying magnetic resonance (MR) signal the steps of: one-dimensional Fourier transforming the time-varying magnetic resonance (MR) signal data along frequency-encode-lines of k space producing complex pairs (R, I) of Fourier transformed data; and, determining from each complex pair (R, I) a phase p for generating a phase profile for the respective frequency-encode line; producing time courses for respective points of the phase profile; Stockwell transform (ST) filtering the time courses; determining new complex pairs (R′,I′) based on the Stockwell transform (ST) filtered time courses; and, one-dimensional inverse Fourier transforming the new complex pairs producing filtered time-varying magnetic resonance (MR) signal data.
