A recently granted patent (Publication Number: US11915346B2) discloses a system that includes a memory and one or more processors configured to perform various operations. These operations involve accessing a current structural estimate of a region of interest, generating a simulated X-ray measurement based on this estimate, receiving a real X-ray measurement, and updating the current structural estimate based on both the simulated and real X-ray measurements. The update process is designed to be invariant to the current structural estimate, ensuring accuracy and reliability in the estimation process.

Furthermore, the system described in the patent involves additional operations such as computing updates based on statistical objective functions, linearly projecting updates into image space, applying regularization techniques for stability, and utilizing machine learning models for generating expected X-ray measurements. The system also allows for the iterative generation of simulated and real X-ray measurements, enabling continuous refinement of the structural estimate. Overall, the patent outlines a comprehensive system for improving the accuracy of structural estimates in X-ray imaging, with a focus on stability, efficiency, and adaptability to different measurement scenarios.
