Segmentation of ribs in thoracic CT scans
Kašík, Ondřej ; Kolář, Radim (referee) ; Jakubíček, Roman (advisor)
This thesis deals with design and implementation of an algorithm for segmentation of ribs from thoracic CT data. For the segmentation method of rib centerlines detection is chosen. The first step of this approach is to extract the centerlines of all the bones located in the scan. These centerlines are divided into short primitives, which are subsequently classified into couple of categories, depending on whether they represent the centerline of the rib. Subsequently, the centrelines of ribs are used as the seed points of the region growing algorithm in three-dimensional space, which realizes the final segmentation of the ribs. Within the work, a database of 10 CT scans was manually annotated, which was subsequently used to validate a performance of the proposed segmentation approach. The achieved success rate of primitive classification is 96,7 %, the success rate of rib segmentation (Dice coefficient) is 86,8 %.

To Dvur Kralove by train - Transfer Terminal in Dvur Kralove nad Labem
Turčanová, Terézia ; Vrbka, Jan (referee) ; Ponešová, Barbora (advisor)
The task of this Bachelor thesis is to create an architectural and urban design of the transfer terminal in Dvur Kralove nad Labem. Therefore in my proposal, I design and integrate the transfer point into an existing built – up area, so it meets the demands of the 21st century passengers, encourages visitors to explore the city and meets daily needs and activities of the local community. Train and bus terminal together with various other services are combined under one roof to create a meeting place. The center of the area is an elevated glazed terminal hall that covers and connects various functions in the separate blocks within it. A distinctive unifying element of the entire terminal is the overlapping roof in the space around the hall and over platforms. The shape of pillars under the roof refers to the character of the industrial zone located nearby and the "lace-shaped" crossing of the ribs under the ceiling creates a specific atmosphere. The shelter over bus stops corresponds with the roof. Simultaneously it fills the interrupted street line on the Ulica 28. rijna street. The project of the area together with its surroundings also includes places for park greenery as well as for living that complement the missing public spaces in this part of town. The scale of objects is chosen with regard to the character of the site and its importance and location within the city, which has about 16 000 inhabitants.

Segmentation Of Ribs In Thoracic Ct Scans
Kašík, Ondřej
This paper deals with rib segmentation in thoracic CT data. For the segmentation method of rib centerlines detection is chosen. The first step of this approach is to extract the centerlines of all the bones located in the scan. These centerlines are divided into short primitives, which are subsequently classified into couple of categories, depending on whether they represent the centerline of the rib. More than 95% of all primitives are classified correctly. In the last step, the rib centrelines are used as the seed points of the region growing algorithm in three-dimensional space.

Case report of physiotherapy care for patient with multiple rib fracture surgery
Vysoudilová, Veronika ; Novotná, Irena (advisor) ; Čechová, Nina (referee)
Autor: Veronika Vysoudilová Title: Case report of physiotherapy care for patient with multiple rib fracture surgery General part: The general section of the thesis focuses on anatomy and kinesiology of thorax. This includes kinematics of respiratory movement and muscle chains connected to thorax. The next part summarizes the knowledge of traumatology, conservative and surgical treatment. The last section states the methods of medical rehabilitation used in treatment of this traumatic condition. Special part: The special part presents a case report of physiotherapy care for patient who underwent surgery of multiple rib fracture. Key words: Case therapy, fracture, ribs, thorax, stabilization
