Abstract
In an endoscope, the tip which contains passages for viewing and light guiding is made of plastics material, for MR compatibility purposes, and an r.f. receive coil of the endoscope is provided with a fiducial having its own r.f. receive coil, to make it possible to track movement of the r.f. receive coil.
Claims18
An endoscope for use in magnetic resonance imaging, the endoscope comprising:
- a distal portion comprised of a non-metallic material and formed such that a plurality of passages are defined therethrough;
- an r.f. receive coil disposed at the distal portion;
- a steerable flexible section connected to the distal portion, the steerable flexible section comprised of a non-metallic material and formed such that a plurality of passages are defined therethrough;
- a plurality of cables comprised of a non-metallic material and connected to the distal portion, for steering the endoscope;
- and
- a fiducial marker disposed at the distal portion and a fiducial r.f coil surrounding the fiducial marker.
An endoscope for use in magnetic resonance imaging, the endoscope comprising:
- a distal portion;
- an r.f. receive coil disposed at the distal portion;
- a fiducial marker disposed at the distal portion in a fixed spatial relationship to the r.f. receive coil;
- and
- a fiducial r.f. coil surrounding the fiducial marker.
A method of reducing artifacts in magnetic resonance imaging when utilizing an endoscope, said method comprising:
- inserting an endoscope into a subject, the endoscope comprising a distal portion, a steerable flexible portion connected to the distal portion, an r.f receive coil disposed at the distal portion, a fiducial marker disposed at the distal portion in a fixed spatial relationship to the r.f. receive coil, and a fiducial r.f coil surrounding the fiducial marker;
- collecting magnetic resonance image data of a subject with the r.f receive coil;
- monitoring motion of the r.f. receive coil with the fiducial r.f. coil and marker;
- and
- adjusting the magnetic resonance image data using the monitored motion of the r.f. receive coil.
