Sphere-fitting algorithm in 3D pore size evaluation and the effect of noise voxels inside a pore. a 2D image presenting a section through the fitted spheres inside the pores (the color is dependent on sphere diameter; the pore walls can be seen in black), b color-coded 3D pore size visualization of a segmented pore in 3D combined with a scaffold matrix visualization (white), c artificially added noise pixels are shown by the red arrow; changes in calculated pore size are apparent. The white scale bar = 500 µm; the color-coded scale bar for b and c is shown on the right; the color-coded scale bar for a is not shown
