Segmentation of blood-vessel tree in whole-body MRI data
 Guricová, Karolína ; Lamoš, Martin (oponent) ; Kolář, Radim (vedoucí práce)
The text brie y describes the anatomy and properties of the blood-vessel system to introduce the characteristics that enable segmentation. Firstly, some of the methods for segmentation of tubular structures from 3D CT or MRI scan are described. Moreover, the approaches using the second derivatives and Hessian matrix are elaborated. To determine the 'vesselness' in the original image, the eigenvalues of Hessian matrix of each voxel of the MRI data volume are computed. Several methods to produce the segmented output image based on these eigenvalues are suggested. The segmentation is implemented in MATLAB. The segmented arterial system is visualized with VTK encoded in Python. Additionally, a GUI is designed to allow measurements within the segmented volume. The lengths of the arteries are measured as a linear approximation of their paths and the results are presented in this work. The limitations of this method
