         5 . The neonate incubator of  claim 3 , wherein the RF channel to enclose the tubing of medical equipment upon shifting of the second cutout of the second cylindrical shell to a position that is substantially opposite with respect to the first cutout of the first cylindrical shell. 
     
     
         6 . The neonate incubator of  claim 1 , wherein the RF shieling comprises preventing an external RF radiation from entering the bore of the MRI device and an RF radiation emitted by the MRI device from exiting the bore of the MRI device. 
     
     
         7 . The neonate incubator of  claim 1 , wherein at least a portion of the RF channel is positioned within the interior chamber of the incubator. 
     
     
         8 . The neonate incubator of  claim 1 , wherein at least a portion of the RF channel protrudes from the RF shielding door towards the external environment. 
     
     
         9 . The neonate incubator of  claim 2 , wherein the RF channel to enable an insertion of the tubing of medical equipment without detaching the tubing from any of the medical equipment ends. 
     
     
         10 . The neonate incubator of  claim 2 , wherein the RF channel further comprising at least one holder to hold a position of the tubing of medical equipment passing through the RF channel. 
     
     
         11 . The neonate incubator of  claim 2 , further comprising at least one holder connected to the RF shielding door to hold a position of the tubing of medical equipment. 
     
     
         12 . The neonate incubator of  claim 11 , wherein the at least one holder comprising:
 a first flexible element having a first proximal end and a first distal end, the first flexible element is connected to the RF shielding door at the first proximal end;   a second flexible element having a second proximal end and a second distal end, the second flexible element is connected to the RF shielding door at the second proximal end; and   a gap bounded by the first flexible element, the second flexible element and a portion of the RF shielding door between the first and second proximal ends.
