SNR and CNR measurements according to image reconstruction method at various doses. In the FBP reference image, scanned at 120 kVp, 50 mAs, the SNR =1.92 and CNR =42.55. ASiR-V, adaptive statistical iterative reconstruction, DLIR, deep learning-based image reconstruction; L, low; M, medium; H, high; SNR, signal to noise ratio; CNR, contrast to noise ratio; FBP, filtered back-projection.
