Electromagnetic tomography for brain imaging: 3D reconstruction of stroke in a human head phantom

Imaging modalities based on electromagnetic tomography (EMT) have become a field of increasing interest and research in recent years. EMTensor GmbH is focused on the application of EMT technology to detect and identify stroke in human brain. In this work, first imaging results based on a 3D reconstruction of a human head phantom featuring a hemorrhagic stroke model are presented. The results have been obtained with the second generation of EMTensor brain scanner, which uses a spherical chamber topology and 177 ceramic loaded waveguide antennas. This investigation illustrates the ability of EMTensor technology to reconstruct relatively large and highly shielded 3D objects together with small contrast inhomogenities placed inside.
