Fig. 3

Qualitative comparison of transverse CT slices for three cases: L082 (Top), N056 (Middle), and L147 (Bottom) processed using different denoising algorithms. The corresponding results are shown for: (a) LDCT input, (b) NDCT ground truth, (c) WDPL-GAN, (d) WC-SNR, (e) TOD-Net, (f) RCN-FTV, (g) WSL, and (h) the proposed method. Zoomed regions of interest (ROIs), highlighted by red squares in the original images are shown below in enlarged views for detailed evaluation. Red arrows indicate white edge artifacts, blue arrows highlight preserved edges, and green and yellow arrows point to small structural details.
