USING COMPLEMENTARY TYPES OF DATA FOR 3D FLAW IMAGING

Non destructive testing (NDT) of some components (of complex shapes for example) requires often the use of several methods that provide complementary information, such as X-ray, ultrasonic, Eddy currents. So, it is interesting develop reconstruction techniques that use all those different types of data. The task is difficult because classical signal processing methods are not to deal with heterogeneous data.
