The study is concerned with developing a 3D-Visuahzation Measurement method based on the Wavelet SVPC theorem. The method is fast to reconstruct images from a few projections, using the Singular Value Decompositions and sampling model objects. In the study, we introduce a Mayer Wavelet sampling model objects and set a local domain for each voxel of the model object, and then we calculate a voxel value in the center of each voxel by using the reconstruction theorem on each local domain.The first, we examined a new algorithm for reconstructing image by means of computer simulation under several Wavelet sampling models, and several conditions of projections. We obtained good conditions between many reconstructing parameters. Automatic cut-off rank of SVD algorithm was found effective.The second, we remodeled a ready-made X-ray equipment into an experimental X-ray CT equipment with image reconstructing function based on the Wavelet SVPC algorithm using. Several experiments made it obvious that the method using a few projections will be useful in several special fields.
