Computertomographie-Verfahren mit kegelförmigen Strahlenbündel, und Computertomograph

摘要

Measurement data are rebinned to number of groups, each group has several levels parallel to each other and to axis of rotation. Each group contains one beam section (411-415). Rebinned data of each group is one-dimensional filtered in direction vertical to direction of levels. Spatial distribution of absorption is reconstruction by back projection of filtered data of several groups.
