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, we present a method that, using 3D microCT images, simulates the behavior of a porosimeter, i.e. an instrument to measure the porous structure of a sample. After segmentation, we perform an intrusion simulation using the distance map, topological skeleton and connected component labeling of the volume’s porous region, which produces a result comparable to the real porosimeter experiment. This initial method has been modified to take advantage of the properties of the Extreme Vertices Model (EVM), which is a very compact form of volume representation with simple base operations. The output is the same yet the computation is faster.
