ABSTRACT:
A method and apparatus are disclosed for reconstructing a 3D CT image of an object from incomplete x-ray cone beam projection data, additionally employing object boundary information from a separate optical scan. A 3D image of the object is reconstructed slice-by-slice by employing, for each slice, a 2D reconstruction procedure for example, filtered backprojection, on the values of the 2D projection images in the plane of the slice to calculate a 2D image of the object for each of the slices.
