  • Method for imaging nuclear magnetic resonance signals by using non-linear magnetic field gradient
    Patent number: 4651098
    Abstract: The phase of nuclear magnetization in a target placed in a homogeneous magnetic field and excited by a high-frequency magnetic field is encoded by applying a specifying magnetic field with a non-linear gradient thereto, and the specifying magnetic field is scanned across the target, and the encoded NMR signals are received and processed so as to produce an image of the distribution of nuclear magnetic substance in the target.
    Type: Grant

    Assignee: Utsunomiya University
    Inventors: Yoshifumi Yamada, Kunio Tanaka, Zenwemon Abe
  • Method of scanning specifying magnetic field for nuclear magnetic resonance imaging
    Patent number: 4594550
    Abstract: The disclosed method of scanning a specifying magnetic field for nuclear magnetic resonance (NMR) imaging comprises steps of generating the specifying magnetic field by synthesis of a static magnetic field and a magnetic field produced by a group of magnetomotive forces, and moving the center of the specifying magnetic field by superposing a scanning magnetic field from a scanner coil in a certain direction of the magnetic field of the group of magnetomotive forces.

  • Method of measuring internal information from a target by using nuclear magnetic resonance
    Patent number: 4573015
    Abstract: The disclosed method comprises steps of alternately applying a strong static magnetic field and a weak homogeneous static magnetic field to a body being measured (target), selectively exciting nuclear magnetic resonance (NMR) at a specific portion of the target by applying a high-frequency magnetic field and a specifying magnetic field thereto, detecting NMR signals from the thus excited portion, and scanning the target by repeating the selective excitation and the detection.
