Unilateral magnetic resonance imaging system with aperture for interventions and methodologies for operating same
An imaging apparatus and methodologies image a subject using an MRI, wherein the imaging apparatus contains only a single sided device for the purposes of imaging structures in the subject.
1. An apparatus for imaging one or more structures included in a subject, the apparatus comprising:
one or more arrays of magnetic materials, at least some of the arrays of materials generating magnetic fields in opposition to other materials in the one or more arrays; and
an access aperture provided through the one or more arrays of magnetic materials to provide access for intervention with the subject of the imaging,
wherein a magnetic field is provided on one side of the apparatus for imaging the subject,
wherein the magnetic field on the one side of the apparatus is used to image the subject using magnetic resonance imaging that is at a distance from the apparatus and from the access aperture,
wherein the apparatus is a single sided device for imaging one or more structures and the access aperture extends through the single side.
2. The imaging apparatus of claim 1 , wherein the apparatus is used to image a pelvic region of a subject.
3. The imaging apparatus of claim 1 , wherein the subject is a living animal or person.
4. The imaging apparatus of claim 1 , where the apparatus forms a magnetic resonance imaging system.
5. The imaging apparatus of claim 1 , wherein the apparatus is an MRI system which includes electro-permanent magnets.
6. The imaging apparatus of claim 1 , wherein an axis of the access aperture is perpendicular to a face of the imaging apparatus.
7. The imaging apparatus of claim 1 , wherein the one or more arrays of magnetic materials include at least one magnetizable component that is, at least in part, a hard-magnetic material and at least one magnetizable component that is, at least in part, of a soft-magnetic material.
8. A method of imaging one or more structures that are at least part or a subject, the method comprising:
positioning an array of magnetic materials on one side of the one or more structures, the array forming an imaging apparatus, which is a single sided device having an access aperture for access to the one or more structures; and
imaging the one or more structures using magnetic resonance imaging using the array of magnetic materials positioned on the one side of the one or more structures,
wherein the magnetic field on the one side of the apparatus is used to image the subject that is at a distance from the apparatus and from the access aperture.
9. The imaging method of claim 8 , wherein the imaging apparatus is used to image a pelvic region of a subject.
10. The imaging method of claim 8 , wherein the subject is a living animal or person.
11. The imaging method of claim 8 , where the array forms a magnetic resonance imaging system.
12. The imaging method of claim 11 , wherein the MRI system includes electro-permanent magnets.
13. The imaging method of claim 8 , wherein an axis of the access aperture is perpendicular to a face of the imaging apparatus.
14. The imaging method of claim 8 , wherein the one or more arrays of magnetic materials include at least one magnetizable component that is, at least in part, a hard-magnetic material and at least one magnetizable component that is, at least in part, of a soft-magnetic material.
