Patent ID: 7400147

Claim:
A self-fastening cage of a magnetic resonance device (MRD) ( 100 ) for providing a homogeneous, stable and uniform magnetic field therein, characterized by an outside shell; said outside shell comprising at least three flexi-jointed superimposed walls ( 1 ) disposed in a predetermined clockwise or counterclockwise arrangement; said MRD comprising: a. at least six side-magnets ( 2 ) arranged in two equal groups being in a face-to-face orientation in a magnetic connection with said outside shell, increasing the overall strength of the magnetic field provided in said cage; b. at least two pole-magnet pieces ( 3 ), arranged in a face-to-face orientation in between said side-magnets ( 2 ); and, c. at least two main-magnets ( 4 ), located on said pole-pieces ( 3 ), arranged in a face-to-face orientation, generating the static magnetic field therein said cage; wherein at least a portion of said side-magnets ( 2 ) are superconductors or ferromagnets.
