| Abstract: | The coded aperture imaging using URA pattern is a new technique for X-ray imaging. It can improve S/N, and has tomographio capability. In this paper, we describe the principle of tomographioal imaging using URA coded aperture in detail, and provide a iterative method for improving tomographioal imaging. The computer simulation using iterative method has been successfully performed. |
