Original abstract
This article deals with presentation of data processing obtained from imaging CT (computer tomography) and micro CT devices. These methods enable to perform bone tissue density analysis by non-invasive way. The image processing methods, by which it is possible to determine mechanical properties of bone tissue, are described in this paper. Further, a creation of a computational model with different bone density of cancellous tissue is described and afterwards the stress strain analysis is performed. The mandible segments with different bone density were used as samples. Results show significantly higher stresses are reached in a cancellous bone tissue with worse bone quality.

Tento článek se zabývá zpracováním dat získaných CT (počítačová tomografie) a mikro CT. Tyto data umožňují provádět analýzu hustoty kostní tkáně. V práci jsou posány metody jak data z CT analyzovat. Dále je vytvořen výpočtový model dvou kostních tkání s různou hustotou a provedena deformačně napěťová analýza. Pro analýzy byly použity dva segmenty dolní čelisti. Výsledky ukazují výrazně vyšší napětí ve spongiózní kostní tkáni s horší kvalitou trámečkvé struktury.
