A number of our customers are doing just that. Creates some amazing results
when one can find flaws "inside" a part.

The first part of the process (CT Image to 3D point data) can be performed
in any number of PD s/w. Once the original images have been processed and
converted into 3D X,Y,Z locations, Imageware's software can perform a full
comparison between the point data and CAD surfaces. The slice comparison is
just a subset of this.
