489. Data base to aid of diagnosis of osteoporotical changes in human pelvic bone

The aim of the work is the facilitation of identification the osteoporotical changes which can contribute to earlier detection of osteoporosis. In the paper the most important information and the main foundations of system to aid of diagnosis of osteoporosis in human pelvic bone are presented. The starting point in modeling of osteoporotical changes is the data from QCT (Quantitative Computed Tomography). The numerical model of analyzed structure is created by conversion of CT images. The next step of work is performing of the strength calculations. The obtained results (distributions of the stresses, strains and displacements) enables to notice the changes in physiological structure of pelvic bone and detecting dangerous states. The essence of aid of diagnosis the osteoporosis is on the base subordinating CT images suitable the effort of the pelvis bone.
