Hey everyone,

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!
