The present invention discloses a novel self-fastening cage of a magneticresonance device (MRD) (100) for providing a homogeneous, stable and uniformmagnetic field therein, characterized by an outside shell comprising at leastthree flexi-jointed superimposed walls (1) disposed in a predeterminedarrangement clockwise or counterclockwise. In a technology of self-fasteningcage, the invention teaches an effective multi-streamed MRD comprising a cageincluding a closed magnetic circuit constructed from strong permanent magnets；and an optional shimming mechanism selected from an array of active shimcoils, passive shimming elements or any combination thereof； a containedcavity within which the magnetic field strength is approximately uniform； anda means, such as a plurality of conveyor belts, pipes or any othertransportation means by which a plurality of samples are introduced into theregion of uniform magnetic field； such that magnetic resonance measurementsare made on a plurality of samples within the region of uniform magneticfield. The invention depicts a cost effective method for obtaining a self-fastening cage of a MRD (100) characterized by an outside shell comprisingsuperimposing at least three flexi-jointed walls (1) so that a homogeneous,stable and uniform magnetic field is provided therein.
