| Abstract: | The one-dimensional x-ray projection came into being as the x-ray passing through the body. The reconstructed projection can bring the two- dimensional X-CT imaging. In this paper, the author discussed the impact on the CT imaging when the source of x-ray emitted the x-ray at the different scope of angle and the acGuisition of projection data is orientated. |
