Title: The Innovations of Tomoo Chiba
Introduction
Tomoo Chiba is a prominent inventor based in Hitachi, Japan, known for his significant contributions to the field of superconducting magnet technology. With a total of eight patents to his name, Chiba has made remarkable advancements that enhance the performance and efficiency of magnetic resonance imaging (MRI) systems.
Latest Patents
Chiba's latest patents include a superconducting magnet apparatus and a magnetic resonance imaging apparatus. The superconducting magnet apparatus is designed to achieve high magnetic field uniformity without increasing the volume of magnetic materials, even in the presence of disturbances. This innovative apparatus features a circular superconducting coil that generates a magnetic field, a coil vessel containing the superconducting coil and refrigerant, and a thermal shield surrounding the coil vessel. Additionally, a vacuum vessel maintains a vacuum around the thermal shield, while magnetic materials are strategically arranged within the vacuum vessel to correct the magnetic field. These magnetic materials are supported by a heat-insulation support medium fixed to the coil vessel.
The superconducting magnet and magnetic resonance imaging apparatus also include a vacuum vessel, a coil vessel, and a superconducting coil for generating a magnetic field. This design incorporates a magnetic member within the vacuum vessel, supported with thermal insulation, to compensate for the magnetic field. A heat exchange device is positioned outside the vacuum vessel to manage heat transfer, and thermal conducting members connect the heat exchange device to the magnetic member through the vacuum vessel. This innovative MRI system utilizes the superconducting magnet to enhance imaging capabilities.
