    • 3D pore analysis of sedimentary rocks 

      Vergés Garcia, Eduard; Tost Pardell, Daniela; Ayala Vallespí, M. Dolors; Ramos Guerrero, Emilio; Grau Carrión, Sergi (2010)
      External research report
      Open Access
      A 3D representation of the internal structure and fabric of sedimentary rocks is of paramount interest to evaluate their structural parameters such as porosity, pore-size distribution and permeability. The classical ...
    • 3D reconstruction and quantification of porous structures 

      Vergés Garcia, Eduard; Ayala Vallespí, M. Dolors; Grau Carrión, Sergi; Tost Pardell, Daniela (2008)
      Article
      Restricted access - publisher's policy
      In this paper, we describe the methodology that we have designed to quantify the pores distribution in bone implants and the empirical results that we have obtained with BioCAD designed scaffolds, microCT and confocal ...
    • A connected-component-labeling-based approach to virtual porosimetry 

      Rodríguez, Jorge Ernesto; Cruz Matías, Irving Alberto; Vergés Garcia, Eduard; Ayala Vallespí, M. Dolors (2011)
      Article
      Restricted access - publisher's policy
      Analyzing the pore-size distribution of porous materials, made up of an aggregation of interconnected pores, is a demanding task. Mercury intrusion porosimetry (MIP) is a physical method that intrudes mercury into a sample ...
    • Bio-CAD analysis of porosity bioimplants 

      Vergés Garcia, Eduard; Ayala Vallespí, M. Dolors; Grau Carrión, Sergi; Tost Pardell, Daniela (2008)
      Conference report
      Restricted access - publisher's policy
      In this work we present two methods to compute the porosity from a μCT image. One is the virtual simulation of a porosimeter and the other is a sphere-based heuristic approach. Both methods obtain a graph representing the ...
    • Design of graphical interfaces for biomedical applications 

      Abellán Moreno, Pascual; Vergés Garcia, Eduard; Tost Pardell, Daniela (2005-05)
      External research report
      Open Access
      The visualization in biomedical applications includes diverse objects in a wide rank of scale, from molecules and cells to physiological, biomechanical and biophysical parts of the body, their anatomy and properties. The ...
    • Hardware and software improvements of volume splatting 

      Vergés Garcia, Eduard; Grau Carrión, Sergi; Tost Pardell, Daniela (2006-05)
      External research report
      Open Access
      This paper proposes different hardware-based acceleration of the three classical splatting strategies: emph{composite-every-sample}, emph{object-space sheet-buffer} and emph{image-space sheet-buffer}.
    • Improved virtual porosimeter 

      Vergés Garcia, Eduard; Ayala Vallespí, M. Dolors (2008)
      Conference report
      Restricted access - publisher's policy
      Recently, the term BioCAD has appeared to refer to the modeling of biological processes. This work focuses on the analysis of structural properties such as porosity of bioimplants for bone reconstruction. Specifically, ...
    • Skeletonless porosimeter simulation 

      Rodríguez, Jorge; Cruz Matías, Irving; Vergés Garcia, Eduard; Ayala Vallespí, M. Dolors (2010)
      External research report
      Open Access
      We introduce a new approach to simulate a virtual mercury intrusion porosimetry (MIP) using neither skeleton computing nor seed-growing methods. Most of the existing methods to determine local pore sizes in a porous medium ...
    • Virtual Porosimeter 

      Vergés Garcia, Eduard; Ayala Vallespí, M. Dolors; Grau Carrión, Sergi; Tost Pardell, Daniela (2008)
      Article
      Restricted access - publisher's policy
      Recently, the term Bio-CAD has appeared to refer to the modeling of biological processes. This work focuses on the analysis of structural properties such as porosity of bioimplants for bone reconstruction. Specifically, ...
