His work has advanced the understanding and application of NMR technology in various scientific and medical fields.
Latest Patents
Yamada's latest patents include a method for imaging nuclear magnetic resonance signals. This method involves encoding the phase of nuclear magnetization in a target placed in a homogeneous magnetic field, which is excited by a high-frequency magnetic field. A specifying magnetic field with a non-linear gradient is applied, and this field is scanned across the target. The encoded NMR signals are then received and processed to produce an image of the distribution of nuclear magnetic substances in the target. Another patent focuses on the method of scanning a specifying magnetic field for NMR imaging. This method comprises generating the specifying magnetic field by synthesizing a static magnetic field and a magnetic field produced by a group of magnetomotive forces. The center of the specifying magnetic field is moved by superposing a scanning magnetic field from a scanner coil in a specific direction.
