CT slice and its enlarged fragments reconstructed, using four iterative algorithms, from low-photon-statistics (340 projections over 180°, for EST, 361 projections for the rest) phase-retrieved (TIE-HOM with γ = 1000) projection data set (E = 38 keV, R2 = 5 m). From left to right: EST reconstruction, iFBP, TV and RL. |
