| Research Abstract |
The study is concerned with developing a fast 3D reconatruction method from a few projections of slant scanning. The point of this method is rapidly to reconstruct 3D images from a few projections of slant scanning, using the Singular Value Decompositions and the sampling model object. The first, we investigated a new algorithm by using the SVD.The results of computer simulation experiments based on the algorithm were good. We obtained good conditions between reconstructing parameters. The second, we tried to design a minute mechanism of slant scanning and software interface with a X-ray equipment, and succeeded in acquisition of a few projecting images. The third, we experimented with the reconstruction algorithm, and succeeded in 3D imaging from a few projection of slant scanning. The 3D images reconstructed were good. Several experiments made it obvious that there is a possibility that the reconstruction method will come into practical use.
