Abstract: A computer-implemented method for monitoring teeth position during treatment includes segmenting three-dimensional dental X-ray image data of teeth in a first treatment state and segmenting optical-scan (OS) image data of the teeth in a second treatment state. The position and orientation of each segmented X-ray crown is compared with the position and orientation of each segmented OS crown to determine any relative position differences and any relative orientation differences. Each segmented X-ray root is repositioned and/or reoriented according to the relative position differences and/or any relative orientation differences, if any, between the corresponding segmented OS and X-ray crowns. The OS crown and the X-ray root are then fused so simulate the roots in the second treatment state without exposing the patient to additional radiation.

Abstract: Systems (100) and methods (400) for medical imaging. The systems (100) may obtain an initial image of an object (118), the initial image may include a first region of interest (ROI) and one or more second ROIs (step 410). The systems (100) may determine, based on the initial image, a first position corresponding to the first ROI and one or more second positions each of which corresponds to one of the one or more second ROIs (step 420). The systems (100) may obtain scan data of the object (118) by causing an imaging device (110) to scan the object (118) based on the first position and the one or more second positions (step 430). The systems (100) may determine an injection parameter of a drug that is injected into the object (118) based on the scan data (step 440). The systems (100) may generate a target image of the object (118) based on the injection parameter and the scan data of the object (118) (step 450).

Abstract: A computer-implemented process for electromagnetic imaging, the process including the steps of: accessing scattering data representing measurements of electromagnetic wave scattering by internal features of an object, each said measurement representing scattering of electromagnetic waves emitted by a corresponding antenna of an array of antennas disposed about an imaging domain containing at least a portion of the object, and as measured by a corresponding antenna of the array of antennas; and processing the scattering data to generate image data representing a spatial location and size of at least one internal feature of the object within the imaging domain; wherein the processing includes applying a trained message-passing graph neural network (GNN) to a graph of nodes representing spatial locations of the antennas and edges representing the measurements.
