Title: Innovations by Toru Segawa in Magnetic Resonance Imaging
Introduction
Toru Segawa is a notable inventor based in Utsunomiya, Japan. He has made significant contributions to the field of medical imaging, particularly in magnetic resonance imaging (MRI). With a total of 3 patents, his work focuses on enhancing the quality and effectiveness of MRI diagnostic apparatuses.
Latest Patents
One of Segawa's latest patents is a magnetic resonance imaging (MRI) diagnostic apparatus capable of eliminating density inhomogeneity of the tomographic images obtained thereby. This innovative apparatus includes a gantry that defines a space for MRI diagnosis, an RF shield located inside the gantry and outside an RF coil, and material designed to correct the distribution of an RF magnetic field during RF transmission or reception by the RF coil. The field correcting material is interposed between the biological body lying inside the shield and the RF coil, and it preferably consists of an aqueous high-molecular gel sheet that is flexibly deformable along the shape of the biological body.
Another significant patent is an RF magnetic shield for MRI. This shield is designed for magnetic resonance imaging apparatuses that have a gradient coil and an RF coil allocated within a generally cylindrical magnet. The RF magnetic shield comprises conductive shielding plate members, which are positioned between the gradient coil and the RF coil, featuring long slits. Capacitors are connected to both longitudinal ends of the slits, with each capacitor being a multilayer capacitor that provides larger capacitance and is continuously and electrically connected to the respective slits.
