US08698499B2 Electromagnet devices compatible with magnetic resonance and MRI devices where circulating current directions alternate between coil groups separated by elevation angles between 26.25 and 55 degrees 有权
与磁共振和MRI装置兼容的电磁体装置，其中循环电流方向在由26.25和55度之间的仰角分开的线圈组之间交替

Electromagnet devices compatible with magnetic resonance and MRI devices where circulating current directions alternate between coil groups separated by elevation angles between 26.25 and 55 degrees
Abstract:
An electromagnet device which generates magnetic field in the direction perpendicular to the inserting direction of an inspection 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 (30), the second coil (32) and the coil group (30) are arranged in this order to increase the angle of elevation θ (θ1
Abstract(Chinese):

通过尽可能地去除不必要的布置，在与检查对象的插入方向垂直的方向上产生磁场的电磁装置的尺寸和重量减小。 还提供了一种磁共振成像装置。 电磁体装置包括第一线圈（31），第一圆形电流（J1）向前循环;第二线圈（32），第二圆形电流（J2）通过该线圈反向循环;线圈组（30） 多个圆形电流（J3-J6）交替地向前和向后循环。 第一线圈（30），第二线圈（32）和线圈组（30）以此顺序排列以增加仰角; （＆Thetas; 1 <＆thetas; 2 <＆thetas; 3）和不包括第二线圈（32）和线圈组（30）的空白区域（S）存在于仰角和角度之间的角度区域中; 2和 ＆thetas; 3。
