Title: Innovations of Yukinobu Imamura in Magnetic Resonance Imaging
Introduction
Yukinobu Imamura is a prominent inventor based in Tokyo, Japan, known for his significant contributions to the field of magnetic resonance imaging (MRI). With a total of 15 patents to his name, Imamura has developed innovative technologies that enhance the functionality and efficiency of MRI apparatuses.
Latest Patents
Imamura's latest patents include a magnetic resonance imaging apparatus designed with a magnetic shield structure to minimize flux leakage. This MRI apparatus features a pair of static magnetic magnets positioned on opposite sides of the imaging space, along with a pair of gradient coils also located on opposite sides. Each static magnetic magnet consists of a disk-shaped magnetic material pole and a ring-shaped magnetic material pole. The gradient coils are equipped with a first coil that applies a magnetic field gradient in the Z-axis direction within the imaging region, and a laminate that shields the disk-shaped magnetic material pole from the magnetic flux produced by the first coil. Notably, the laminate has varying thicknesses, being thinner in the Z-axis direction on the ring-shaped magnetic material pole side compared to the center portion of the imaging space.
Another significant invention is the open-type magnetic resonance imaging apparatus, which includes a pair of static magnetic field magnets and a pair of gradient magnetic field coils. Each static magnetic field magnet is designed with a discoid magnetic pole that generates a static magnetic field in the Z-axis direction, while an annular magnetic pole creates a static magnetic field on the X-Y plane. The gradient magnetic field coils are equipped with a Z coil that provides a magnetic field gradient in the Z-axis direction, along with a magnetic material block that shields the discoid magnetic pole from magnetic flux generated by the Z coil.
