Title: Innovations of Jang-Yu Hsu

Introduction

Jang-Yu Hsu is an accomplished inventor based in Solana Beach, California. He holds a total of 2 patents that showcase his contributions to the fields of magnetic resonance imaging and coherent radiation sources. His innovative work has made significant impacts in technology and engineering.

Latest Patents

One of Hsu's latest patents is a method for determining shim placement on tubular magnets. This method utilizes ferromagnetic shims to reduce the inhomogeneity of the magnetic field in a Diameter Spherical Volume (DSV) within the bore of a Magnetic Resonance Imaging (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 reduce field inhomogeneity to acceptable levels.

Another notable patent is the development of a gyro free electron laser, which serves as a source of coherent radiation. This invention includes an evacuated drift tube that receives a beam of relativistic electrons and provides coherent radiation at its output end. A relativistic electron supply generates the electron beam, while a magnetic field causes the electrons to spiral. An azimuthal wiggler accelerates the spiraling electrons, and an axial magnetic field controls their gyroradii.
