Abstract
The present invention relates to systems and methods of performing magnetic resonance imaging (MRI) in awake animals. The invention utilizes head and body restrainers to position an awake animal relative to a radio frequency dual coil system operating in a high field magnetic resonance imaging system to provide images of high resolution without motion artifact.
Claims10
A dual coil system for magnetic resonance imaging, the system comprising:
- a surface coil;
- a volume coil having a cylindrical non-magnetic core module having an outer surface and a longitudinal axis, a cylindrical bore extending through the core module along the longitudinal axis and defining an inner surface;
- a plurality of conductive strip lines, the strip lines extending parallel to the longitudinal axis on the inner surface of the core module;
- a pair of circuit boards carried at the ends of the core module;
- and a plurality of resonating elements, each of the resonating elements including one of the strip lines and at lease one tuneable capacitor.
2 more elements
A surface coil comprising;
- a curvilinear support surface having a concave inner surface and a convex outer surface;
- a circuit board assembly;
- at least a pair of conductive strips carried on the concave inner surface;
- at least one capacitor connecting the conductive strips;
- and
- a tuneable variable capacitor.
