From: Post-processing sets of tilted CT volumes as a method for metal artifact reduction
Metal artifacts are clearly suppressed. Left: Mean of the six reconstructions in Figure 3. The streaking artifacts are still visible, but to a lesser degree. Right: Median of the six reconstructions in Figure 3. The streaking artifacts are strongly suppressed. In both cases, details in the vicinity of the metal inset become much more visible, e.g. the thin gap of air around the inset (arrow); in comparison to a single reconstruction, noise is reduced as an additional benefit. The inset shows the ring-shaped region of interest for the calculation of bias, error and noise around the metal body.
