Assessment of Registration Methods for Cranial 3D Modelling
Three-dimensional (3D) models are a useful tool for cranial deformation analysis in infants. The registration of the head 3D models to a known coordinate system is vital for the obtainment of parameters and indexes that quantify deformation.

Standard method for microCT-based additive manufacturing quality control 2: Density measurement
MicroCT is best known for its ability to detect and quantify porosity or defects, and to visualize its 3D distribution. However, it is also possible to obtain accurate volumetric measurements from parts – this can be used in combination with the part ...

Laser Deposition Cladding On-Line Inspection Using 3-D Scanner [PDF]
Laser deposition directly deposits metal cladding to fabricate and repair components. In order to finish the fabrication or repair, 3-D shape of the deposition needs to be inspected, and thus it can be determined if it has sufficient cladding to ...
