Magnetic Resonance Imaging at higher field strengths has several design challenges that must be addressed for optimal performance and image resolution. We have developed a cantilever system that is suspended in the magnet to eliminate phase noise that are produced due to vibrations generated by gradient coils. The cantilever system has features such as detachable quadrature RF coils, animal cradle system with in-built water & anesthesia and tuning/matching capability outside the bore. The system is not only centered in all three axes but also has tuning capability in the z-direction from outside the bore so we could move the subject in and out to center in the bore.
