ARTIFACT MITIGATION IN THREE-DIMENSIONAL IMAGING

摘要

The present invention relates to a method for refining calibration of an imaging system comprising acquiring image data from a measurement volume that includes a three-dimensional object having one or more known parameters, identifying a first projection contour of the three-dimensional object in the image data, analytically determining a second projection contour of the three-dimensional object using the one or more known parameters and a model of the imaging system, and refining a calibration of the imaging system by minimizing a deviation between the first projection contour and the second projection contour.
