I have two 3D CT images, one is a sub-volume of the other. I want to measure to what extent the sub-volume is similar or representative to the bigger one. The CT images are binary; containing pores and solids and I need to correlate only pores in the 2 volumes, their distribution, sizes and connectivity. Any help?
Dear Ali Elabd Mohamed ,
Digital Volume Correlation (DVC) is a novel technique for full 3D strain and deformation measurements. The technique imports volume images of the component in reference and deformed states and is able to calculate the full 3D displacement and strain map. Images are typically acquired from X-ray Computed Tomography (X-ray CT) systems, but can equally be obtained by Magnetic Resonance Imaging (MRI) or Optical Coherence Tomography (OCT) systems for biological subjects, or via optical techniques for transparent media. DVC is a powerful nonintrusive technique for the identification of sub-surface material deformation and is capable of identifying defects, discontinuities or other material characteristics.

Hi Ali Elabd Mohamed ,
You can also try Dragonfly software (www.theobjects.com) from Object Research Systems, it is free for non commercial use.
Dragonfly has a plugin for Object Analysis that will be useful for your measurements. Also, Dragonfly is a great correlative tool since you can visualize multiple volumes of different resolution at the same time.
Do not hesitate to contact me if you want more information.
