    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.

    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: Microwave examination of individuals is carried out by transmitting microwave signals from multiple antenna locations into an individual and receiving the backscattered microwave signals at multiple antenna locations to provide received signals from the antennas. The received signals are processed to remove the skin interface reflection component of the signal and the corrected signal data are provided to a hypothesis testing process. In hypothesis testing for detecting tumors, image data are formed from the test statistic used to perform a binary hypothesis test at each voxel. The null hypothesis asserts that no tumor is present at a candidate voxel location. The voxel threshold is determined by specifying a false discovery rate to control the expected proportion of false positives in the image. When the test statistic value associated with a voxel is greater than the threshold, the null hypothesis is rejected and the test statistic is assigned to the voxel. For voxels where the test statistic falls below the threshold, the null hypothesis is accepted and the voxel value is set to zero. The resulting image indicates the locations or other characteristics of detected tumors.
