Extraction and use of X-ray specific density following object-based three-dimensional reconstruction.
Given a set of three-dimensionally reconstructed objects and the source X-ray images from which the reconstructions have been derived, it is shown how the uniform or smoothly varying X-ray specific densities (i.e. CT coefficients) of these objects can be derived. It is considered how that information can be used, inter alia, to synthesise conventional X-ray images (with unconventional refinements), or to compute tomographic slice images (but without textural information.
