Method for assembling a magnetic field generator for MRI |
摘要 |
<p>A magnetic field generator for MRI comprises upper and lower magnet units, each including a plate yoke and a permanent magnet, and a column yoke magnetically connecting the part of magnet units. When the magnet unit and the column yoke are connected, the column yoke or the magnet unit is lowered so that a guiding rod attached to an end face of the column yoke is inserted into a hole formed in the magnetic unit. Further, the column yoke is guided by a guiding member disposed between a permanent magnet on the plate yoke and a position where the column yoke is to be connected on the plate yoke. <IMAGE></p> |
