CCTA exam (70 bpm, 70% R-R phase) with bright and dark streaks from calcification and effect of motion correction and beam hardening correction. Left: No motion correction, with multi-material beam hardening correction; Center: With motion correction, no multi-material beam hardening correction; Right: Fully corrected (for both motion and beam-hardening). Left inset: Difference image (with vs without motion correction); Center inset: Difference image (with vs without multi-material beam hardening correction). Top row W/L: 900/200; Bottom row W/L: 1600/400; Insets (W/L = 900/0) (Credit: UCSD)
