Title: Innovations of Bizhan Dorri in MRI Technology

Introduction

Bizhan Dorri, based in Clifton Park, NY, is a prolific inventor known for his significant contributions to magnetic resonance imaging (MRI) technology, holding an impressive total of 44 patents. His work focuses on enhancing the capabilities and efficiency of MRI systems, helping to advance medical imaging solutions.

Latest Patents

Among his latest innovations is a cryogenic-fluid-cooled open MRI magnet with a uniform magnetic field. This inventive MRI magnet comprises first and second spaced-apart superconductive coil assemblies, each housing a toroidal-shaped coil containing a superconductive main coil partially immersed in cryogenic fluid such as liquid helium. To address the magnetic field distortions often present in such systems, each coil assembly is associated with a generally non-permanently-magnetized ferromagnetic ring. These ferromagnetic rings, coaxially aligned with the associated coil assembly, effectively improve the magnetic field's uniformity in the imaging volume.

Another notable patent by Dorri is a method for actively and passively shimming a magnet. This method allows for addressing magnetic field inhomogeneities in MRI systems by utilizing correction coils and specified shim locations. The magnetic field is measured to determine the inhomogeneity, while linear programming optimizes the currents and shim sizes to minimize overall inhomogeneity and resource usage.
