I have to analyse a 3D Dicom image stack of titanium foam regarding it’s porosity, pore size, web thickness and window size between the pores. I used BoneJ for my Calculation but i’m not sure if it’s the best way to analyse the structure or my results are correct. Maybe you have a better idea?
Porosity: BoneJ > Particle Analyzer to get the Volume and the enclosed Volume of the foam
Vol. (mm³) = 619 239, 235
encl. Vol. (mm³) = 602 929, 375 (what exactly does ImageJ calculate here?)
To calculate the porosity I devide the Pore Volume (encl. Volume???) by the total volume. I tried Volume fraction to get the total volume, but the number was so high it couldn’t be correct (TV = 94 050 000 mm³). Is there an other way to get the total Volume of the structure?
Web thickness: BoneJ > Particle Analyzer to get the mean local thickness
Thickness (mm) = 9,3 mm (that seems correct to me)
Right now i’m struggeling to find a way to analyse my mean pore size and the window size between the pores.
Is there a common way to do it?
i would really appreciate it if you can give me some answers to my questions!
Thanks a lot!
