Abstract
In an MRI apparatus, a static magnetic field is generated by a pair of magnets facing each other within a spacing. An axis direction of a subject inserted within the spacing is orthogonal to that of the static magnetic field. Gradient magnetic fields with X, Y and Z direction are generated by two pairs of plane coils, two pairs of plane coils, and a pair of plane coils, respectively, arranged between a pair of magnets. The plane coils for generated the gradient magnetic field in X direction is the same form as the plane coils for generating the gradient magnetic field in Z direction. By such an arrangement, gradient magnetic fields generated within the spacing have enough magnitude and linearity to obtain magnetic resonance signals. It is also enough spacing to insert a subject.
