Rotatable protective cover functioning as a door for MRI system
A rotatable protective cover functioning as a door, that both opens and closes off, an entrance opening of a patient bore in an MRI device is disclosed. The rotatable protective cover comprises a semi-permeable barrier material, MRI shielding, and physical shielding; and is at least partially transparent.
1. A rotatable protective cover functioning as a door, that both opens and closes off, an entrance opening of a patient bore in a Magnetic Resonance Imaging (MRI) device, said rotatable protective cover comprising:
a connector hinge coupled to the protective cover, that couples the protective cover onto the MRI device in a rotatable manner, such that when a patient is positioned within the patient bore of the MRI device, the protective cover is rotatable with the connector hinge so that the entrance opening of the MRI device patient bore may be either covered or uncovered; and
the rotatable protective cover being a semi-permeable barrier constructed from a material that is at least partially transparent and provides both magnetic shielding and radio frequency shielding when the rotatable protective cover is positioned in order to completely cover the entrance opening of the bore.
2. The rotatable protective cover according to claim 1 , wherein said semi-permeable barrier material is made at least partially of connected strands of flexible or ductile material.
3. The rotatable protective cover according to claim 2 , wherein said connected strands of flexible or ductile material comprises a material selected from the group consisting of metal and fiber.
4. The rotatable protective cover according to claim 1 , wherein said semi-permeable barrier is constructed of a material selected from the group consisting of copper, paramagnetic materials, ferromagnetic materials, and any combination thereof.
5. The rotatable protective cover according to claim 1 , wherein said semi-permeable barrier has a structure of either a mesh, a web or a net.
6. The rotatable protective cover according to claim 1 , wherein said rotatable protective cover is transparent.
7. The rotatable protective cover according to claim 1 , wherein said rotatable protective cover further comprises a ring frame that is disposed around the perimeter of said rotatable protective cover.
8. The rotatable protective cover according to claim 1 , wherein when said rotatable protective cover is in a closed position, the entrance opening of said MRI device is completely covered by said rotatable protective cover.
9. The rotatable protective cover according to claim 1 , wherein said magnetic shielding extends over an area that is at least equal to an open area of said patient bore entrance opening of the MRI device.
10. The rotatable protective cover according to claim 1 , wherein said connector hinge is configured such that upon opening, said rotatable protective cover remains attached to said patient bore entrance opening of the MRI device.
11. The rotatable protective cover according to claim 1 , wherein said rotatable protective cover has a shape selected from the group consisting of:
tubular, cone shaped, cup shaped, cylindrical, sleeve-like, or any combination thereof, and the rotatable protective cover is hollow while having a perimeter that is configured to match the bore of said MRI device and an internal shape configured to match an object placed within the bore of the MRI device.
12. The rotatable protective cover according to claim 1 , wherein said rotatable protective cover has a shape which can be mated to an incubator, when an incubator is desired to be positioned within said MRI device.
