Fig 2. The increase in average absolute error (AAE) of all standard CT reconstructions of the phantom containing three amalgam implants as a function of the position of the slice.

Fig 2

A high error was observed in a 9 mm wide region around the amalgam implants at 0 mm. In addition, a high error was observed at -48 mm and +24 mm which were caused by movement of the tongue and the upperjaw due to the insertion of amalgam implants respectively.
