CT-Method using a conical beam |
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. |
