Summary

Low-cost X-ray tomographic imaging methods may be useful for detecting defects in structural ceramics. Conventional film-based tomography systems, although potentially inexpensive, produce images that are affected by blurring caused by the structure of the object above and below the tomographic plane of interest. The blur can be removed by using digital image processing techniques. We will discuss three methods for deblurring images of ceramic specimens: inverse filtering, iterative approximation, and multiplane approximation.
