Tomographic Image Reconstruction Techniques for Spectroscopic Sources: Theory and Computer Simulations

摘要

Computerized tomography (CT) offers one method for accurately reconstructing the spatial features of a spectroscopic source having arbitrary geometry. With computer-simulated lateral projections as the input data, the potential advantages and problems associated with several CT algorithms were compared. In general, CT offers greater spatial information content than more commonly used image-reconstruction techniques, but at the added expense of more involved post-processing calculations and more elaborate experimental instrumentation.
