Head‐and‐neck multichannel B1 + mapping and RF shimming of the carotid arteries using a 7T parallel‐transmit head coil

Neurovascular MRI suffers from a rapid drop in B into the neck when using transmit head coils at 7 T. One solution to improving B magnitude in the major feeding arteries in the neck is to use custom RF shims on parallel-transmit head coils. However, calculating such shims requires robust multichanne...
