| 摘要 |
<p>A system for synthesizing a radiation divergence correcting operation and a deconvolution operation, for use in a tomographic apparatus, comprising optical storing means for a collection of primary signal profiles in analog form obtained by exposing a subject to a substantially flat, and diverging beam of penetrating radiation from different directions, and collecting the radiation transmission at positions, corresponding to the associated angles of incident radiation; projecting means for sequentially projecting primary signal profiles in an annular region of a memory device; and read out means including a rotating filter for sequentially and in correspondence to a correcting deconvolution function reading out simultaneously all information elements as are stored in different ones of said primary signal profiles and as are included in a particular one of said trajectories.</p> |
