Latest Patents
One of his latest patents is titled "Filtering artifact from fMRI data using the Stockwell transform." This invention relates to a method for filtering time-varying MR signal data prior to image reconstruction. A one-dimensional Fourier Transform (FT) is applied to the time-varying MR signal data along each frequency-encode line of k space. The phase of each complex pair of the FT transformed data is calculated to create a phase profile for each frequency-encode line. This process is repeated for all time points of the time-varying MR signal data. The time course of each point within the phase profile is then transformed into the Stockwell domain, producing Stockwell Transform (ST) spectra. Frequency component magnitudes indicative of an artifact are determined and replaced with a predetermined frequency component magnitude. Each of the ST spectra is then collapsed into a one-dimensional function. New real and imaginary values of the complex Fourier data are calculated based on the collapsed ST spectra, which are transformed using one-dimensional inverse Fourier transformation to produce filtered time-varying MR signal data. This method is highly advantageous as it easily identifies high-frequency artifacts within the ST spectrum and filters only frequency components near the artifacts. Consequently, high-frequency artifacts are substantially removed while preserving the frequency content of the remaining signal, enabling the detection of subtle frequency changes occurring over time.
