✦ Synopsis

Accurate images of body cross sections can be obtained from certain straightforward but lengthy computational operations on X-ray shadowgrams (projections). It is suggested that clinical radiographic data could be processed rapidly and economically by &king use of computergenerated holograms. A simple method is described for constructing such holograms by overprinting teletype characters with a standard lineprinter. Preliminary experimental results are reported. Reconstructed images of an aluminium cylinder and a bovine shin bone are presented.
