Improve the reconstructed view in particular cases

In some cases (inhomogeneous and/or anisotropic configurations), the reconstructed views are badly shaped. For example, the data are superimposed or some “holes” appear. These phenomena are clearly visible on the second image below. The configuration simulates a weld inspection by using a sectorial scanning; the weld is defined in different anisotropic volumes with a particular crystallographic orientation, and the porosity is modeled by a spherical flaw.

 

 

 

These behaviors are due to the fact that data is reconstructed along a path based on the central ray and, in some cases, this ray can be locally affected (e.g. : particular incidence compared to an interface, impact point of the ray on a junction between several interfaces, etc.).

In order to bypass this problem, the “Smoothing” option is very useful. It is located in the toolbox at the bottom of the screen.

 

 

Compared to the left view of the second image above, the use of the “Smoothing” option gives a much better reconstructed view.
