X-ray computed tomography allows scanning the internal attenuation coefficient of a part. In X-ray domain, this coefficient highly depends on the materials. To perform a dimensional measurement from the volumetric data, a surface (i.e. point cloud)

Ultrasound waves are preferably used as means to provide details about the inner structure of materials, thus providing a way to non-destructively evaluate the quality of produced components. Nevertheless, ultrasonic data are strongly a ected by a mu
