| Abstract: | The technology of wavelet analysis has been playing an important role in the field of engineering technology. CT (Computed Tomography) technique is one of the miracles in the field of medical imaging diagnose. In this paper, Wavelet sampling theorem has been extended from 1D to 2D, with which the ART method in Cross-sectional CT has been improved. Computer simulation results show that the wavelet analysis method in image reconstruction which has been put forward in this paper has an advantageous character. |
