Z-Index Parameterization (ZIP) for Volumetric CT Image Reconstruction via 3D Dictionary Learning
Despite the rapid developments of x-ray cone-beam CT (CBCT), image noise still remains a major issue for the low dose CBCT. To suppress the noise effectively while retain the structures well for low dose CBCT image, in this work, a sparse constraint based on the 3D dictionary is incorporated into a...
