摘要：

The design of a computerized tomographic system is considered. The algorithms for digital filtering and two-dimensional interpolation are analyzed. The disturbances introduced by the small number of projections, the finite impulse response of the filter, rounding and crude interpolation are discussed. Finally a recently developed algorithm for tissue absorption compensation is briefly summarized. © 1979.
