Latest Patents

Yoshiharu Mohri's latest patents include groundbreaking inventions focused on improving the efficiency and effectiveness of MRI apparatus. The first patent details a "Magnetic resonance imaging apparatus having vibration damping means." This innovative device comprises a magnet for generating a static magnetic field and gradient coils designed for producing gradient magnetic fields in a measurement space. A unique vibration damping mechanism is integrated within the apparatus, utilizing a container filled with granular material. This design ensures that the gradient coil remains stationary without vibrations or deformations, thereby promoting the generation of accurate image signals free from acoustic noise.

The second patent, named "Vibration reduction system for magnetic-resonance imaging apparatus," addresses the inherent challenges of noise generated within MRI machines. It describes a system where superconducting magnets create a large, uniform magnetic field. The coils responsible for generating magnetic field gradients are supported on a bobbin, which must endure various forces. Mohri's invention employs tubes or hollow members attached to the bobbin, containing movable bodies such as particulate material. This configuration allows the energy from the coils' forces to cause the movable bodies to collide, dissipating energy and minimizing noise, thus enhancing the overall imaging experience.
