Research study of mechanical properties of cranial tissue
Wojtek, Lukáš ; Valášek, Jiří (referee) ; Marcián, Petr (advisor)
This bachelor thesis deals with the problematics of determining mechanical properties of cranial bone tissue. In this thesis a search study associated with an experimental determination of mechanical properties of bone tissues is executed. A brief history and progress of imaging methods and their importance of computation modelling are introduced. There are descriptions of histomorfometric parameters describing a structure of bone tissue at the micro level, ways of their computation and their impact on mechanical properties of bone tissue. Practical part of the thesis is focused on processing micro-CT images of cranial bone as well as analysing histomorfometric parameters (BV/TV, TbTh, TbSp) and subsequently stress strain analysis of selected sections of cranial bone tissue. Resulting Young´s modulus of elasticity of bone tissue [MPa] are compared with results from experiments from literature.

Determination of mechanical properties of cancellous bone tissue of skull bone
Votava, Tomáš ; Borák, Libor (referee) ; Marcián, Petr (advisor)
This bachelor thesis is focused on determination of mechanical properties of cancellous bone tissue of cranial bone. In research part of this study are described methods of medical imaging, mechanical properties of cranial bone tissue and anotomy of skull. Next one are described studies focused on determination mechanical properties of cancellous bone. Finally are decribed histomorphometric parameters and their measurement using software I$mageJ2$ and plugin $BoneJ2$. In practical part of this thesis, there are described measurement procedure, measurement results, 3D geometry modelling procedure by reconstruction micro-CT images and determination of mechanical properties solved by computational modeling using FEM. Five speciments are analyse predominantly from os occipitale. On first specimen is analyzed influence of thresholding settings.

Estimation of mechanical properties of the cancellous bone tissue of the proximal tibia
Leinweber, Vít ; Valášek, Jiří (referee) ; Marcián, Petr (advisor)
This bachelor thesis is focused on the determination of mechanical properties of cancellous bone tissue of proximal tibia. In the beginning of the work there is theoretical part which consists of a description of the tibia anatomy from macroscopic and microscopic view, treatise on the bone tissue growth, influences affecting the bone tissue growth and description of mechanical properties of the bone tissue. In the end of the theoretical part there is a detailed review of related literature to this work. In the practical part morphometric parameters are measured using software ImageJ and plugin BoneJ. The process of creating a computational model is described and results of mechanical properties are presented. Regression models of mechanical properties and histomorphometric parameters are created from these results.
