[Research highlight of image reconstruction today].
In today's image processing researches, image reconstruction is a highlight. It includes the following several aspects: (1) reducing noise before reconstruction or after reconstruction under time-frequency constraints; (2) researches for reconstruction of motion organ; (3) image reconstruction from incomplete projection data; (4) direct volume reconstruction and 3-D image rendering; (5) researches for non-X-ray CT; (6) researches for parallel processing system of CT. In this paper, an introduction to these aspects is given.
