Wide tuned volume coil for small animal MRI on 4.7T
Original language description
Wide tuned radiofrequency volume coil for Small Animal MRI allows receiving of MR signals on wide-band different frequencies. For this reason, it is possible to work with 19F and 1H resonance without changing a special individually coil. The images for different nucleus do not require movement with the animal. Therefore, 1H and 19F images can be easily compared. The birdcage construction of this coil allows volume imaging of small rodents, for example mice. Speciality of this coil is advantageous use of distributed parameters of transmission lines. This solution improves homogeneity of fields, improve resonance quality factor, and allows homogeneous tuning on many points at the same time. The advantage is also the price reduction for elimination of many nonmagnetic lumped capacitors. On 4,7T resonance it works from 185 to 203MHz. Classic Birdcage constructions works only with 3% frequency tuning. A coil produces signal levels comparable with classical one frequency coils. Quality factor unloaded coil is Q200 = 328 a Q188= 331. A Coil was tested on 4,7T Bruker Biospin located at IKEM, Prague.
