Synopsis

A small-size, light-weight, cryogen-free 7T animal MRI system is being developed in IEE CAS. The magnet system has been completed and acceptable magnetic field strength and homogeneity indices have been achieved. The gradient assembly with passive shimming is going into the final assembly stage and the RF coil is ready for tunning. The integration of the whole system will be very soon and a mouse experiment will be conducted then. It is expected the ultimate product will largely boost the scientific research activities that are unapproachable to advanced MRI scanners.
