Geometric Calibration for Cone Beam CT using Line Fiducials

Unmet NeedTraditional BB-based geometric calibration methods for cone-beam CT (CBCT) rely significantly on foreknowledge of the scan trajectory shape. This is a hindrance to the implementation of variable trajectory CBCT systems, normally requiring a dedicated calibration phantom or algorithm for every scan orbit of interest. A more flexible method...
