SHUTTING ASSEMBLY FOR CLOSING AN ENTRANCE OF AN MRI DEVICE
First Claim
1. A shutting assembly for a magnetic resonance imaging device (MRD) bore aperture, comprising at least one first movable portion and at least one second portion affixed to said MRD, wherein said shutting assembly further comprising a normally closed or normally open sliding mechanism, further wherein said sliding mechanism couples at least one first moveable portion to at least one said second portion affixed to the MRD, thereby enabling a reciprocal movement of at least one said first moveable portion parallel to said MRD bore aperture in an upwards and downwards directions in respect to at least one said second portion affixed to said MRD.
