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.

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.

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.
