In this work we present a regularized CSI-EPT method.
Furthermore, we extend the reconstruction algorithm such
that multiple B1+ data sets for different shim (antenna
phase) settings can be simultaneously included in the
iterative CSI-EPT process leading to an overall
improvement of the reconstructed dielectric
values.Electric field and dielectric tissue property
maps where retrieved for in vivo simulations and phantom
experiments.
