Statistical image reconstruction for low-dose CT using nonlocal means-based regularization. Part II: An adaptive approach
To reduce radiation dose in X-ray computed tomography (CT) imaging, one common strategy is to lower the tube current and exposure time settings during projection data acquisition. However, this strategy would inevitably increase the projection data noise, and the resulting image by the conventional...
