2. Reliability and reproducibility of three-dimensional cephalometric landmarks using CBCT: a systematic review
Objective : The aim of this study was to review the reliability and reproducibility of 3D-CBCT (cone beam computed tomography) cephalometric landmark identification. Methods : Electronic databases (Pubmed, Scopus, Web of Science) were searched for papers published from 1998 to October 2014. Specific strategies were developed for each database, with the guid

3. Analysis of anatomical landmarks of the mandibular interforaminal region using CBCT in a Brazilian population
Aim: To evaluate the position, presence, appearance and extent of various anatomical landmarks in the mandibular interforaminal region of Brazilian patients using cone-beam computed tomography (CBCT). Methods: A total of 142 CBCT examinations were analyzed to determine the most common location of the mental foramen (MF), the presence and extent of the anteri

5. Characterization and three-dimensional reconstruction of pores of self-reducing pellets done by EAF dust
This work focused on the characterization physical and microstructural of the self-reducing pellet made of Electric Arc Furnace (EAF) dust using different low cost techniques. The serial sectioning technique was used to evaluate detailed measurements of pore connections, tortuositiy of pores and porosity distribution. The chemical analysis using Inductively

8. Determination of the Representative Elementary Volume for the study of sandstones and siltstones by X-Ray microtomography
X-Ray computerized microtomography (µ-CT) besides providing two-dimensional images (2-D) of the transversal sections of the sample, the biggest attraction of the methodology is the rendering of three-dimensional images (3-D), enabling a more real analysis of the porous structure of the rock. However, the reconstruction, visualization and analysis of such 3-

12. Visualização volumétrica aplicada às Geociências
This paper is on volume visualization of spatial data. It aims at showing new possibilities to visualize three-dimensional phenomena such as geology, soils, geophysics, seismic and the like. The use of volumes in the evaluation processes allows one to visualize and to explore the phenomenon as a continuous body in space, thus incorporating the third dimensio
