Deep IR reconstruction for low-dose CT scans

(A) The schematics of deep IR reconstruction framework.

(B) The ROC curves of three models, including FBP with reference dose, FBP with a lower dose, and deep IR with a lower dose.

(C–E) Representative images reconstructed by FBP and deep IR at 8.00 mGy (40% of a normal dose) (C) and ultra-low doses of 0.67 (D) and 0.61 mGy (E).

(F) Mean opinion score from two radiologists evaluating the chest and abdomen parts of the images. Statistical analyses are performed between R1 and R2 using Mann-Whitney U tests with ∗∗∗∗p < 0.0001.
