Abstract: A tomographic imaging system, including a data processing component having a memory and at least one processor configured to: access scattering parameter data representing electromagnetic waves scattered by features within an object and originating from a plurality of antennas disposed around the object on a boundary S; process the scattering parameter data to generate a reconstructed image representing a spatial distribution of features within the object, said processing including: solving an electromagnetic inverse problem, wherein forward and inverse steps of the inverse problem are represented and solved as respective differential equations involving an electric field to determine values for the electric field; and process the determined values of the electric field to generate reconstructed image data representing one or more spatial distributions of one or more electromagnetic properties within the object.

Abstract: A computer-implemented process for continuous monitoring of a brain stroke during a critical rehabilitation period, the process including the steps of: (i) accessing initial image data representing an initial image of a subjects brain containing a stroke region; (ii) accessing scattering parameter data representing microwaves scattered by the subjects brain and originating from a plurality of antennas disposed around the subjects brain; and (iii) processing the scattering parameter data and the initial image data using a gradient-free optimisation method to generate estimates of spatial dimensions of the stroke region within the subjects brain, wherein the initial image of the subjects brain is used as a priori information to improve the accuracy of the generated estimates, and the spatial dimensions of the stroke region are generated as global parameters of the gradient-free optimisation method.

Abstract: A computational electromagnetics system has a memory and at least one processor configured to execute a computational electromagnetics process. The process includes solving a pair of differential equations for only two variables, the two variables representing a pair of scalar potentials, and determining at least one of an electric field and a magnetic field from the pair of scalar potentials.
