PROBLEM TO BE SOLVED: To provide a magnetic resonance imaging apparatus which reduces transmission of noises generated owing to the vibration of a gradient magnetic field coil to an imaging space.
SOLUTION: An enclosure cover 7 is arranged around a scanner gantry. The enclosure cover 7 is arranged non-contact with a static magnetic field generating means 1 and stands independently using leg parts 7f. The enclosure cover 7 is also arranged inside of an irradiation coil 3 that locates at a position nearest to the imaging space in such a way that the enclosure cover does not come into contact with the gradient magnetic field coil 2 and the scanner gantry, and covers the imaging space. A bed 5 is supported by a rail formed in one piece with the enclosure cover 7 so that it can move in the major axis direction of the imaging space. As the enclosure cover 7 completely covers the scanner gantry including the gradient magnetic field coil 2 and a vacuum vessel, the enclosure cover reduces transmission of noises generated from the gradient magnetic field coil or the like to the imaging space.
