The matching network is significant, yet sometimes
overlooked, component of MRI RF Coils. The matching
network can have an impact on the local SAR values,
especially when 1): the simulated coils are designed for
use inside the subject/patient body 2): the tissues near
the matching network are already exposed to high SAR
values without the inclusion of the matching network. A
case study of an endo-rectal coil for 7T prostate
imaging with numerical tool showed that the matching
network has large impact on the local SAR and is not
negligible for MRI RF coils specified above.
