Development of block cycling inversion methods in computer tomography (English)
0 references
The base problem of computer tomography, i.e., the 3D inverse Radon problem, is analysed by an improved block cycling inversion method. The 3D formulation problem is decomposed for a series of 2D problems with the same Radon matrix. The main advantages of the modification applied are the realisation simplicity due to the absence of main minors degeneration and to a better index of stability. The singularity problem is in turn solved also. The approach considered and the results obtained can be used as a software for the 4th-generation tomographs.
