Very High Order Shim Inserts VHOS
Whole Body Gradients
RRI’s very high order shim insert (VHOS) addresses the strong susceptibility shifts arising from the frontal sinuses, oral cavity and auditory canals during MR at 3T and higher fields. These shifts, which cause dropout, signal voids and poor SNR, result from higher order field harmonic spatial terms and cannot be cancelled in standard commercial scanners, where shimming of impurities is implemented up to the 2nd order only
RRI currently has multiple whole body gradient coil designs in process. All of our designs have new state of the art technology and will be available in high performance as well as low to medium performance applications.
