The workflow presents four sequential domains. In L D C T Acquisition, an X-ray source rotates around an object and produces Projection Data displayed as stacked projection strips. In the Sinogram Image Domain, an Incomplete-view Sinogram Image is transformed into a Full-view Sinogram Image. In the Reconstruction Domain, the Full view Sinogram Image generates a Reconstructed C T Image of an axial body section. In the C T Image Domain, a Low quality C T Image is refined into a High quality C T Image. Arrows indicate the directional flow between each stage.The incomplete-scan CT reconstruction process can be classified into three domains based on the processing stage. The workflow is divided into the Sinogram image domain (pre-processing), reconstruction domain (3D volume reconstruction) and CT image domain (post-processing). methods applied in the Sinogram and CT image domains are categorized as image processing techniques, while the reconstruction domain specifically refers to the 3D volumetric reconstruction process
