In many fields, researchers take advantage of knowledge of material's porosity. For obtaining quantitative information of single, enclosed cavities, a lot of methods have been developed. The situation gets complicated when pores are interconnected within the structure. This is the case of foams and scaffolds, which are used in modern biology research for tissue engineering. X-ray computed microtomography (CT) is a non-destructive method for 3D imaging of materials. A result from tomographic measurement is a set of slices through the sample, where grey values correspond to linear attenuation coefficient. These slices can be stacked and then imaged and processed as 3D data. For getting quantitative information about porosity in foams or scaffolds scanned with CT, many software offer various approaches. We compare different software for pore analysis in terms of provided result, accessibility, quantitative analysis, field of application and user-friendliness. As a testing sample, a tomographic data of hydroxyapatite foam for bone replacement were used.
