Abstract
Official abstract text for this publication.
A device and method for imaging includes a magnetic resonance imaging system, and an oculus for inspection of a structure of interest. The oculus includes or is attached to at least one sensor for determining the location of the oculus with respect to the magnetic resonance imaging system or the structure of interest.
First claim
Opening claim text (preview).
1 . An apparatus comprising: a magnetic resonance imaging system, and an oculus for inspection of a structure of interest, wherein the oculus includes or is attached to at least one sensor configured to determine the location of the oculus with respect to the magnetic resonance imaging system or the structure of interest. 2 . The apparatus of claim 1 , wherein the at least one sensor is sensitive to electromagnetic fields emanating from the structure of interest. 3 . The apparatus of claim 2 , wherein the sensor is a coil. 4 . The apparatus of claim 1 , wherein the oculus includes a transmitter of electromagnetic fields absorbed by the structure of interest. 5 . The apparatus of claim 4 , wherein the transmitter is a coil. 6 . The apparatus of claim 1 , wherein a portion of the oculus is hollow or at least partially transparent. 7 . The apparatus of claim 1 , wherein a portion of the oculus is configured to display an image of the structure of interest. 8 . The apparatus of claim 1 , wherein the structure of interest is not enclosed by a volume of the magnetic resonance imaging system. 9 . The apparatus of claim 1 , wherein the magnetic resonance imaging system includes one or more electropermanent magnets. 10 . A method of inspecting a structure of interest comprising: providing a magnetic resonance imaging system, and positioning an oculus including or is attached to at least one sensor configured to determine the location of the oculus with respect to the magnetic resonance imaging system or the structure of interest in the proximity of a structure of interest, and operating the oculus in the presence of a magnetic field produced by a the magnetic resonance imaging system. 11 . The method of claim 10 wherein a procedure is guided based in images produced with the aid of the oculus. 12 . The method of claim 10 , wherein the at least one sensor is sensitive to electromagnetic fields emanating from the structure of interest. 13 . The method of claim 12 , wherein the sensor is a coil. 14 . The method of claim 10 , wherein the oculus includes a transmitter of electromagnetic fields absorbed by the structure of interest. 15 . The method of claim 14 , wherein the transmitter is a coil. 16 . The method of claim 10 , wherein a portion of the oculus is hollow or at least partially transparent. 17 . The method of claim 10 , wherein a portion of the oculus is configured to display an image of the structure of interest. 18 . The method of claim 10 , wherein the structure of interest is not enclosed by a volume of the magnetic resonance imaging system. 19 . The method of claim 10 , wherein the magnetic resonance imaging system includes one or more electropermanent magnets.
