Abstract
A magnet device is provided with two static magnetic field generating sources 14a and 14b disposed so as to oppose each other while placing a person to be inspected therebetween, a vessel 15 containing the static magnetic field generating source 14a and a vessel 16 containing the static magnetic field generating source 14b, and the vessels 15 and 16 are disposed at positions asymmetric with respect to the person to be inspected.Thereby, a magnet device and an MRI device using the same which can extend a space above the person to be inspected on a bed while avoiding introduction of a large scale device which causes to increase the manufacturing cost thereof.
