Latest Patents

One of her latest patents is a method for determining shim placement on tubular magnets. This innovative method utilizes ferromagnetic shims to reduce the inhomogeneity of the magnetic field within a Diameter Spherical Volume (DSV) in the bore of an MRI device. The process involves establishing a magnetic field, defining the DSV, and measuring the field strength at its surface. A Legendre polynomial is derived to model the inhomogeneity, and coefficients for harmonic terms are calculated and evaluated. Ferromagnetic shims are then strategically attached to the bore's surface to minimize field inhomogeneity.

Another notable patent is for an open access superconducting MRI magnet. This design features an open access frame with spaced parallel end plates and includes a superconducting coil assembly. The invention incorporates an apparatus for minimizing hysteresis, which consists of a layer of nonferromagnetic conducting material placed between the gradient coils and end plates. This layer effectively reduces AC eddy current hysteresis, enhancing the overall performance of the MRI system.
