ELECTROMAGNET DEVICE AND MAGNETIC RESONANCE IMAGING DEVICE

WIPO Patent Application WO/2008/062599

A1

An electromagnet device which generates magnetostatic field in the direction perpendicular to the inserting direction of an inspecting subject is reduced in size and weight by removing unnecessary arrangement as much as possible. A magnetic resonance imaging device is also provided. The electromagnet device comprises a first coil (31) through which a first circular current (J1) circulates forward, a second coil (32) through which a second circular current (J2) circulates reversely, and a coil group (30) through which a plurality of circular currents (J3-J6) circulate alternately forward and reversely. The first coil (31), the second coil (32) and the coil group (30) are arranged in this order to increase the angle of elevation θ (θ1<θ2<θ3), and a blank region (S) not including the second coil (32) and the coil group (30) exists in the angular region between the angles of elevation θ2 and θ3.
