Foamed materials in general and aluminium foams in particular demonstrate a number of interesting properties due to their porous structure, which makes them usable in a wide range of applications. Problems in the production and application of metal foams arise from incomplete mastery of the process parameters, so often uneven and unpredictable structures and variations in property values are obtained. In closed cells, due to the existence of the outer crust, there is no visible internal structure of metal foam or the size and shape of the cell and whether the cells are homogeneously distributed throughout the sample. The size, shape and distribution of the cells have a significant influence on the mechanical properties of the metal foam and therefore it is of great importance to have an insight into the internal structure that is formed during the foaming process. To analyse the entire metal foam cross section, it is necessary to carry out a test using an internal structure analysis such as CT. Computed tomography is a method that uses X – rays to capture a large number of two – dimensional (2D) object views at different angles. The resulting 2D views are then translated into the 3D view of the scanned object.
