MAGNETIC FIELD GENERATOR FOR MRI, ITS ASSEMBLING, AND ASSEMBLING OF MAGNET UNIT USED THEREFOR

摘要

PURPOSE: To make assembling and connecting easier to enable a magnetic field generator for MRI to be efficiently assembled by carrying a polarized magnet block slid on a plate york and pressing the carried magnet block against a projection or a magnet block coated by an adhesive to adhere both. CONSTITUTION: A first magnet block 7 is carried on a plate york 1 along an equally dividing line of an angle made by a protrusion 5 and a guide rail 6 i.e., on the line to make the angleαinto 45°, to be placed on the corner part of the protrusion 5 side. At this time, the magnetic block 7 is slid as is attracted on the plate york 1. When the distance between the carried magnet block 7 and the protrusion 5 comes to a prescribed distance, carrying is stopped and an adhesive is applied on the face of the protrusion 5 to be adhered on the magnet block 7, though an adhesive is not applied on the side face of the guide rail 6. After that, carrying is restarted and the magnet block 7 is pressed against the protrusion 5. When a prescribed time is elapsed in a condition that the magnet block 7 is pressed against the protrusion 5, the adhesive is hardened to adhere both.
