【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 acquisition of projection data is orientated.更多还原
