Abstract: A system for detecting human entry into a container using electromagnetic imaging to generate image maps of the container. The system includes a door monitor configured to detect an entry door open event associated with the container. The system uses one or more processors and a memory with instructions to generate a baseline image map of the container, detect an entry door open event with the door monitor associated with the container, generate a post entry door open event image map of the container, and compare the baseline image map generated before the entry door open event with image map generated after the entry door open event.

Abstract: A novel, integrated dual-modal breast imaging system that requires minimal or no movement of the breast between scans. A static receptacle holds the breast or other target object still. An acoustic imaging fixture with acoustic transducers, and an electromagnetic imaging chamber with electromagnetic antennae, each perform imaging of the target object when occupying a respective working position of surrounding relationship to the receptacle, and at least one thereof is movable relative to said static receptacle into and out of the respective working position, without repositioning of the static receptacle. Acoustic imaging is performed, and prior information extracted from the sound-speed image is incorporated into the electromagnetic inversion algorithm, whereby low-resolution sound-speed reconstructions are used to improve tumour detection via electromagnetic imaging.

Abstract: In one embodiment, a system, comprising: one or more processors; and a memory comprising instructions, wherein the one or more processors are configured by the instructions to: receive first electromagnetic data at a plurality of frequencies; process the first electromagnetic data; and generate prediction parameters by passing the processed first electromagnetic data through a neural network trained on data corresponding to a synthetic training set, the prediction parameters corresponding to a container and contents located within the container.

Abstract: A method for electromagnetic imaging of containers receives uncalibrated first data corresponding to signals of a first plurality of different frequencies associated with an antenna array residing in a container having contents. The method estimates of a second data based on a computer model and simulation of signals of a second plurality of different frequencies associated with the antenna array, the second plurality of different frequencies including a subset of the first plurality of different frequencies. The method compares magnitudes, without corresponding phase comparisons, of the first and second data at each frequency of the second plurality of different frequencies. The method updates the second data based on the comparing. The method provides information about the contents within the container based on the updated second data.

Abstract: Exemplary methods and systems may image an object of interest using one or more waveguide assemblies including gated elements. The gated elements may be configurable in a transmission state, a reception state, or a passive state. The exemplary methods and systems may deliver electromagnetic energy (e.g., microwave energy) to an object of interest using a gated element of a waveguide assembly configured in a transmission state and sample scattered field using a gated element of another waveguide assembly configured in the reception state while the remainder of gated elements are configured in the passive state.

Abstract: Exemplary imaging systems, apparatus, and methods may include a plurality of reconfigurable antenna assemblies. The reconfigurable antenna assemblies may each include one or more antennas. The antennas may be configured in a plurality of states including a passive state in which the antenna may not perturb the electromagnetic field. The antennas may be positioned about a measurement domain such as, e.g., a conductive measurement chamber.

Abstract: Methods and systems may image an object of interest using one or more probes. More specifically, such exemplary methods and systems may deliver electromagnetic energy (e.g., microwave energy) using a transmitting antenna to the object while activating a probe to interact with the scattered field and sampling the resulting scattered field using one or more receiving antennas. The sampled electromagnetic energy may then be used to reconstruct an image of the object.

Abstract: Methods and/or systems are disclosed herein for use in imaging an object with microwave tomography using a plurality of different boundary conditions.
