Abstract

The reconstruction of images from profiles has recently received wide attention as the result of the development of x-ray scanners that produce tomograms, or density maps of thin slices through an organ, without the presence of confusing contributions from background or foreground objects situated out of the slice of interest. This very important application to medical imagery now invites further development along many lines. Reduction of scanning time is necessary, both to increase the amount of work that one instrument can do and to permit work on moving organs such as the lungs and heart. Reduction of x-ray dosage is also desirable.
