Combination of multichannel receive data for local cr-MREPT

Convection-reaction equation based MREPT (cr-MREPT) is known to reconstruct electrical properties (EPs) also in transition regions where EPs vary. However it results in artifacts in regions where the convective field is low. Use of multichannel receive data with different and possibly non-overlapping low convective field regions provides the opportunity for artifact free reconstruction of EPs. In this study, a method is developed for combining multichannel receive data to image EPs in a local region of interest. The method has been successfully applied in both phantom and healthy human brain experiments.
