Low-Dose CT Image Denoising with Improving WGAN and Hybrid Loss Function

Figure 14

The effect of the parameter in our hybrid loss function on the validation set from the MDLCT dataset. Under the detail images, the noise level of each CT image (the difference between each result and the LDCT image). From the left to the mid column ([0, 0.995]), the noise level of CT image gradually decreases as the increases. From the mid column to the right column ([0.995, 3.0]), the noise level of CT image increases as the increases.
