1. An imaging system with in situ real time determination of imaging geometries by which individual two-dimensional (2D) x-ray projection images are captured for three-dimensional (3D) image reconstruction, the imaging system comprising:

  • an x-ray source;

    a detector positioned relative to the x-ray source, the detector being configured to obtain the individual 2D x-ray projection images of an object from a plurality of spatial positions and orientations of the x-ray source and/or the detector relative to the object;

    an optical-based in situ real time geometry calibration device to determine a spatial position and orientation of the x-ray source and the detector relative to the object and to each other for each of the individual 2D x-ray projection images; and

    an image processing system configured to reconstruct a 3D structure of the object from the individual 2D x-ray projection images and associated imaging geometry parameters.
