Abstract
A multi-planar intraoral radio frequency (RF) coil apparatus for use in a magnetic resonance imaging system can include a housing having a shape configured to be positioned in an occlusal plane between an upper jaw and a lower jaw of a subject and a plurality of coil elements disposed within the housing. The plurality of coil elements includes a first coil element positioned in a first plane and a second coil element positioned in a second plane different from the first plane and substantially parallel to the first plane. The coil elements can be loop coil elements or dipole coil elements.
Claims18
A multi-planar intraoral radio frequency (RF) coil apparatus for use in a magnetic resonance imaging system, the RF coil apparatus comprising:
- a single housing having a shape configured to be positioned in an occlusal plane between an upper jaw and a lower jaw of a subject;
- and
- a plurality of RF coil elements disposed within the housing, the plurality of RF coil elements comprising:
- a first RF coil element positioned in a first plane substantially parallel to the occlusal plane;
- and
- a second RF coil element positioned in a second plane different from the first plane and substantially parallel to the first plane and the occlusal plane;
- wherein the plurality of RF coil elements are configured to form at least one channel that is configured to receive one or more teeth of the upper jaw and one or more teeth of the lower jaw of the subject.
A radio frequency (RF) coil apparatus for use in a magnetic resonance imaging system, the RF coil apparatus comprising:
- an extraoral RF coil configured to be positioned on a surface of a subject;
- and
- a multi-planar intraoral RF coil comprising:
- a single housing having a shape configured to be positioned in an occlusal plane between an upper jaw and a lower jaw of the subject;
- and
- a plurality of RF coil elements disposed within the housing, the plurality of RF coil elements comprising:
