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.

Object-based three-dimensional X-ray imaging.

A form of three-dimensional X-ray imaging, called Object 3-D, is introduced, where the relevant subject material is represented as discrete 'objects'. The surface of each such object is derived accurately from the projections of its outline, and of its other discontinuities, in about ten conventional X-ray views, distributed in solid angle. This technique is suitable for many applications, and permits dramatic savings in radiation exposure and in data acquisition and manipulation. It is well matched to user-friendly interactive displays.
