Micro-computed tomography-based quantification of pore size in electron beam melted titanium biomaterials

6-pagesThis paper presents a new method for the quantification of pore size of scaffold biomaterials from micro computed tomography (µCT). A two dimensional implementation of a spherical pore approximation model and a novel pore quantification algorithm have been applied to actual and phantom µCT reconstructions and the accurate measurement of pore size has been demonstrated. This paper describes the circular pore model used for the two dimensional analysis, a spherical pore model for three dimensional analysis, the algorithm for quantifying pore size, and the mechanics of the algorithm for both the 2-D and 3-D implementations
