    The paper deals with measurement of the deformation field in the internal structure of trabecular bone. The strain field is determined from time–lapse tomographic measurements, where a sample of trabecular bone is compressed and its internal microstructure is simultaneously scanned using X-ray microtomography. For the imaging a novel micro-CT system suitable for imaging of a sample under applied load has been used. A digital image correlation method is applied to the acquired image data to calculate the displacement and strain fields in the microstructure. The acquired data provides reliable basis for verification of our microstructural Finite Element models.
