Compensating severe non-linearities caused by high-density objects.The problem of metal and high-density objects The reconstruction of the same data with MAR applied.Typical dental slice (real patient) with massive metal parts (crowns) within field of view.MAR Exxim has developed and implemented an iterative algorithm for 3D reconstruction, which mitigates non-linearities caused by high-density and metal objects. In Cobra it is called MAR (metal artifact reduction) mode. This method is approximately only 2.5 times slower than standard Feldkamp. |
