X-ray computed tomography of mouse embryo
Šejnohová, Marie ; Walek, Petr (referee) ; Kolář, Radim (advisor)
The aim of this semestral thesis is to compare the possibilities of available micro-CT systems. Theoretic part of this thesis there deals with possibilities of staining soft tissues and embryos because of enhancement the contrast of micro-CT images. Here follows a description of sources X-ray and detectors of available micro-CT systems. In practice there was realized the staining of embryo in cooperation with Department of histology and embryology in Brno. Then followed a measuring on FSI in Brno, ČVUT in Prague and synchrotron Elettra in Italy. In semestral thesis are described of the thesis there are compared the micro-CT systems and results of measuring embryos by means of presented systems and results are compared.The best results were obtained on micro-CT in Brno, where X-ray tube and flat panel detector were used. This images were used for a segmentation of cartilage olfactory system by means of 3D region growing. From results they were created 3D models for comparison with a manually segmented model. A less accurate results were obtain with the semi-automatic segmentation but this method isn’t too time-consuming.

Hort, Tomáš ; Nováková, Eva (referee) ; Kolář, Radim (advisor)
The subject of this thesis is the newly built Sport-relax center in Velké Meziříčí. The built will have two above ground. On the first floor will be a reception with a café and fitness center. Part of the fitness center will be a spinning hall and a small exercise room on the mats. On the second floor will be a sauna center, massages and a center for physiotherapists and nutrition counseling. Individual operations in a multifunctional house are selected with respect to the location. The town of Velké Meziříčí has launched a competition for the construction of this area by a sports-cultural house. For this reason, these sites are located in the house.
Classification of the vascular tree in fundus images
Tebenkova, Iuliia ; Kolář, Radim (referee) ; Odstrčilík, Jan (advisor)
Retinal image analysis plays a very important role, as human gets around 90% of environment information with the help of eyes. Automation of process of retinal image analysis promotes to improve the efficiency of retinal medical examinations. The following thesis is dedicated to automatic classification methods of retinal vascular system images obtained from a digital fundus camera. Vessel classification method using classifier on the base of neural networks, which is trained and then tested on the retinal vessel segments, is investigated and implemented. In this thesis anatomical retinal survey, properties of image data from digital fundus camera and retinal image classification methods are briefly described. The last chapter is devoted to the evaluation of efficiency of retinal vessel classification with automatic methods.
Kindergarten FUTURUM
Lišuchová, Želmíra ; Erben, Adam (referee) ; Pavlovský, Tomáš (advisor) ; Kolář, Radim (advisor)
The topic of this bachelor´s thesis is design of a newly-built kindergarten FUTURUM based on architectural study made in my 5th term of bachelor´s study in the subject AG034 Architectural Design Studio 4 – Interior and Architectural Space. The project consists of construction study and realisation documentation. Two-storey kindergarten with 2 classrooms is situated in quarter Brno-Stránice near Brno city centre. The building is a part of complex of Christian grammar and primary school “Cyrilometodějské gymnázium a ZŠ“. The idea of project is to use local materials and renewable energy sources; local construction companies to be involved in realisation, to make a comfortable architectural space for education and self-development of new generation and encourage them to overcome fears, defy limitations and start thinking creatively. In symbols, it reacts to the influence of pandemic and hectic lifestyle on children´s psyche and sketches guidance to life with God in accordance with Christian values and ethic at this kindergarten. The newly-built object is located in the middle flat part of a plot, southwestern and northeastern part is sloped. It is block-shaped with lateral axis parallel with street Havlíčkova. There is a block cut out of the main block in eastern upper edge (terrace) and in the southern lower part (recessed entrance). The main entrance to a cantilever in the 2nd floor is from Havlíčkova Street over the footbridge on subtle columns. There are offices of director, teachers, isolation occasionally used for speech therapy, terrace, play room, sleeping room, locker room and washroom. On the 1st floor, there is another play room with facilities, technical and other facilities. Food will be cooked and delivered from school kitchen. Entrance from school grounds is nearby. Bidirectional wall slab structural system is made of cast-in-place reinforced concrete. Foundations too due to low load-bearing capacity of subsoil. Flat green roof has an internal drain.
The Rekonstruktion of Vyškov Rectory
Vaňurová, Tereza ; Hrabec,, Josef (referee) ; Vojtová, Lea (advisor) ; Kolář, Radim (advisor)
The basis of the thesis is the architectural study, prepared in the winter semester of the third year of bachelor study on the topic of rectory renewal in Vyškov. The task of the study was to find suitable urban, mass and functional solution of the existing building and adjacent land. The former rectory will be completely renovated and will mainly serve the original purpose for accommodation of dean and chaplain of the parish, meetings with believers, religious education, then there will be located a chapel, a workroom, studios and rooms for commercial rent. On neighboring land will be designed new city park with design stage. The new building will serve as a platform for the expression of art, which enrich the cultural life in Vyskov. Together with the park which serves as a multifunctional public space for relaxing. The work is divided into design studies, project documentation for construction and architectural detail.
Utilization of 3D ultrasonography for nuchal translucency measurment
Širůčková, Anna ; Harabiš, Vratislav (referee) ; Kolář, Radim (advisor)
This thesis is review of the newest methods of diagnose congenital defects of fetus in first trimester mainly Down´s syndrome. Nuchal translucency is primary marker for assessment the risk of aneuploidy. The aim of this project is to clarify the most modern techniques, three dimensional ultrasound, using for measuring of nuchal translucency. Fetal Medicine Foundation set straight guidelines for measuring, practice and audits, which are recommended. In this thesis, the focus is also on possible ways of audit by quantitative and qualitative evaluation. In the last part, I designed the study for evaluation of presented techniques. The aim is to qualify the benefits of tool Sono NT and Volume NT.
Newly-built of a building
Čavojská, Petra ; Nováková, Eva (referee) ; Kolář, Radim (advisor)
The diploma thesis processes the documentation of project which displays a building of school facility with an area for kindergarten and center of leisure time.

Detection of foreign objects in X-ray chest images using machine learning methods
Matoušková, Barbora ; Kolář, Radim (referee) ; Chmelík, Jiří (advisor)
Foreign objects in Chest X-ray (CXR) cause complications during automatic image processing. To prevent errors caused by these foreign objects, it is necessary to automatically find them and ommit them in the analysis. These are mainly buttons, jewellery, implants, wires and tubes. At the same time, finding pacemakers and other placed devices can help with automatic processing. The aim of this work was to design a method for the detection of foreign objects in CXR. For this task, Faster R-CNN method with a pre-trained ResNet50 network for feature extraction was chosen which was trained on 4 000 images and lately tested on 1 000 images from a publicly available database. After finding the optimal learning parameters, it was managed to train the network, which achieves 75% precision, 77% recall and 76% F1 score. However, a certain part of the error is formed by non-uniform annotations of objects in the data because not all annotated foreign objects are located in the lung area, as stated in the description.
Optical disc detection in ophthalmologic images
Melša, Ondřej ; Harabiš, Vratislav (referee) ; Kolář, Radim (advisor)
This work is target on the detection of center and border of optical disk in AF (autofluorescent) and IR (infrared) images. The image are primarily modified at brightness area. The center of optical disk are sought after by algorithms, which offers program Matlab. As well are search border of optical disk. Results are comparison with engaged results and then is calculated effectivity of created algorithm.
