Sparse View CT Reconstruction Algorithm Based on Non-Local Generalized Total Variation Regularization

Sparse View CT Reconstruction Algorithm Based on Non-Local Generalized Total Variation Regularization

CT image reconstruction algorithm based on generalized total variation (TGV) can overcome the staircase effect of total variation (TV) regularization, thereby protecting the structural features of the reconstructed image transition region. Although the TGV reconstruction method is superior to the TV...
