Abstract
To prevent image quality deterioration of an image due to a variable magnetic field generated by a fan motor provided in a position where a measuring magnetic field leaks, a magnetic resonance imaging apparatus has a gantry including a static magnetic field generating magnet; a gradient magnetic field generating coil; and an irradiation coil, a table for placing the object, and an input/output device including a display device and is provided with at least a pair of cooling fan motors arranged almost symmetrically to the central axis that extends along the long-axis direction of the cylindrical space and is located in the center in the horizontal direction of the static magnetic field generating magnet or the vertical plane passing through the central axis.
