Abstract: This paper Mathematically present six basic theorems and their numerical computation methods in the field of image reconstruction. With the development of large-scale integral circuits Systolic array the present methods for reconstructing directly images may be implemented real-time. The results of computer simulation are presented for illustrating the efficiency of the proposed methods.
