Latest Patents
One of her latest patents is titled "Fourier shifting of voxel boundaries in MR chemical shift imaging." This invention utilizes phase shifting in k space to translate voxels in a chemical shift imaging (CSI) system. By applying the Shift Theorem for finite Fourier transforms, she maximizes the enclosure of an object of interest within a minimal number of voxels. This computational approach allows for voxel shifts to be accomplished with minimal manipulation of raw data after the patient has left the imaging facility. The resulting spectral data is less diluted by the surrounding tissue's spectrum.
Another notable patent is the "Method and apparatus for automated magnetic field shimming in magnetic resonance spectroscopic imaging." This automated process employs doubly phase encoded NMR spin echo responses and multiple Fourier transformations to derive spectroscopic plots for each voxel in a three-dimensional array. The derived hydrogen peak frequency serves as a measurement of the static magnetic field intensity within that voxel, allowing for adjustments to shim coil currents to minimize field nonuniformity. The auto shimming procedure can be applied iteratively to achieve the desired field uniformity.
