Abstract: A system for wearable/man-portable electromagnetic tomographic imaging includes a wearable/man-portable boundary apparatus adapted to receive a biological object within, a position determination system, electromagnetic transmitting/receiving hardware, and a hub computer system. The electromagnetic transmitting/receiving hardware collectively generates an electromagnetic field that passes into the boundary apparatus and receives the electromagnetic field after being scattered/interferenced by the biological object within. The hub computer system performs electromagnetic tomographic imaging based on the received electromagnetic field.

Abstract: An electromagnetic tomography system for gathering measurement data pertaining to a human head includes an image chamber unit, a control system, and a housing. The image chamber unit includes an antenna assembly defining a horizontally-oriented imaging chamber and including an array of antennas arranged around the imaging chamber. The antennas include at least some transmitting antennas and some receiving antennas. The control system causes the transmitting antennas to transmit a low power electromagnetic field that is received by the receiving antennas after passing through a patient's head in the imaging chamber. A data tensor is produced that may be inversed to reconstruct a 3D distribution of dielectric properties within the head and to create an image. The housing at least partially contains the antenna assembly and has a front entry opening into the imaging chamber. The head is inserted horizontally through the front entry opening and into the imaging chamber.

A method for electromagnetic imaging includes imaging a biological tissue via an electromagnetic tomography system, recording electrical activity of the biological tissue via a biomedical electrical recording system, and correlating dielectric properties of the biological tissue with an electrical signal recorded by the biomedical electrical recording system.

Abstract: Methods and systems for 4D electromagnetic tomographic differential (dynamic) fused imaging and mapping of electrical excitation of biological tissues. A plurality of electromagnetic field sources and detectors generate and detect an electromagnetic field domain in a target area. A biological tissue is positioned within the target area, and an electromagnetic field domain is generated via a selected plurality of sources. The field generated by each source is selectively characterized so that each of a selected plurality of detectors recognizes a source of field from the plurality of sources. The sources and detectors are controlled so that fields generated by the selected sources are received by the selected detectors after interacting with the tissue. Based on the field received at each detector, a complex interference (scattering) matrix is derived from the tissue-generated field, and anatomical and functional image information are reconstructed from this matrix.
