Title: MAGNETIC RESONANCE IMAGING DEVICE
Abstract:
This MRI device (1) is provided with: a static magnetic field generating device (2) including a static magnetic field generating source (2a, 2b) which generates a uniform magnetic field (7) in a space; a gradient magnetic field generating device (3) including a gradient magnetic field generating source (3a, 3b) which superimposes a gradient magnetic field (9) onto the uniform magnetic field (7); between the static magnetic field generating source (2a, 2b) and the gradient magnetic field generating source (3a, 3b), a vessel (12) which stores magnetic bodies used to adjust the uniformity of the uniform magnetic field (7); and a guide (13) which accommodates the vessel (12). Two types of guide having different lengths in the direction of the uniform magnetic field (7) are arranged as the guide (13). By this means it is possible to provide an MRI device (1) with which it is possible to reduce vibrations without increasing the wall thickness of the gradient magnetic field generating device (3).
