Abstract

Micro-tomographic imaging with a spatial resolution on the micrometer scale offers owes a high potential to perform certain types of measurements that were not feasible with other techniques or conventional laboratory methods. The synchrotron X-ray source gives substantial advantages because of its high brilliance and continuous X-ray spectrum. Based on this, visualized the microstructure of rat bone and lumber vertebra was visualized using 20, 25 and 30 keV synchrotron X-rays. We utilized the data which was acquired at different energies for multi-model imaging and to estimate the Ca/P ratio. Up to now there has been no research carried out using these images for the estimation of the calcium content, with synchrotron X-rays. The results are based on the analysis of images and gray values obtained at different energies. We introduce this new method in order to measure the calcium content by means of high resolution synchrotron micro-CT.
