Green-EPT

Motivation: All previous methods for MR-based Electric Properties Tomography suffer from some drawback. Improvement is desirable. Goal(s): To develop an approach for in vivo MR-based Electric Properties Tomography, which performs well in terms of both accuracy and precision. Approach: The dielectric properties are reconstructed by imposing the validity of Green's identity to the measured B1+ data, combined with suitable regularization and post-processing. Results: Good quality reconstructions are obtained working on simulated data, heterogeneous tissue-mimicking phantoms, and in vivo. These promising outcomes suggest that the technique deserves further development. Impact: Green-EPT is a new approach for MR-based Electric Properties Tomography. Validation tests, including in vivo studies, demonstrate that the approach performs well and is worth pursuing further.
