Inventor: JANG WOO JU ALBERT
IPC: A61B5/00
Filed: 2021-05-24
Abstract: The present invention relates to a head-dedicated magnetic resonance imaging device. A head-dedicated image is acquired while a subject's head is positioned at the center of a magnetic field of a main magnet installed inside a housing. Alternatively, an image of a target part (for example, mouth part, ear part, eye part) selected from the head is acquired by utilizing a local coil fabricated to be inserted into or worn on the subject's body. An anti-vibration unit is installed on the periphery of the housing so as to absorb vibrations resulting from the Lorentz force generated by the magnetic field of the main magnet and an electric current applied to an inclined magnetic field coil during image acquisition while the housing is suspended on an installation frame. According to the present invention, images are acquired after parts of the head and shoulders are moved into the housing without having to move all of the subject's body into the housing, thereby making it possible to reduce the device size. The device thus can be installed and used at small-scale hospitals, and can be comfortably used for subjects with claustrophobia. Body parts other than the head are allowed to move during imaging such that functional magnetic resonance imaging (fMRI) for measuring brain activity can be acquired easily and variously. Use of the local coil makes it possible to acquire images of the target part selected from the head with a high signal-to-noise ratio. Vibrations generated during image acquisition while the housing is suspended on the installation frame are absorbed, thereby removing noise and image shades that would otherwise occur due to the vibrations.
