Fig 4

The average absolute error (AAE) with and without different metal artifact reduction (MAR) techniques.

(a) The AAE between reference scans, for scans without MAR, for scans with the commercial MAR technique and for scans corrected using the MDT software. For S3, MAR2 is displayed. (b) The AAE reduction after the application of both the commercial MAR techniques and the metal deletion technique (MDT).
