To the knowledge of the author, the theory of the accuracy of the output of existing x-ray scanners has yet to be placed on a sound mathematical basis.

For practical purposes it will be sufficient to reconstruct f (or find an approximation to f) with finite resolution. Any picture in the real world has finite resolution, anyway.

How a Reconstruction Approximates a Real Life Object,Since the objective function is never in the pixel reconstruction space, i. e., Z(n), it is not sufficient to resolve the problem by simply showing (as was done in Chapters III through VII) that if f is in Z(n), then the problem of reconstruction from projections can be made well-posed.
