Meta-analysis of bone tumorous lesions in spinal CT data using convolutional neural networks
Nantl, Ondřej ; Jakubíček, Roman (referee) ; Chmelík, Jiří (advisor)
This bachelor thesis deals with the use of convolutional neural networks in the meta-analysis of bone tumor lesions in CT image data. The theoretical part describes the anatomy and pathology of bone tissue, machine learning, discusses the functionality of convolutional neural networks and summarizes selected existing methods for computer-aided diagnosis of vertebra bone lesions. In the practical part, various types of models using convolutional neural networks were implemented and the networks were trained on an available augmented dataset. Finally, the results of various types of models were statistically evaluated, compared with available articles and discussed.

Deep-learning based segmentation of pathological tissue in brain MR images
Nantl, Ondřej ; Kolář, Radim (referee) ; Chmelík, Jiří (advisor)
This diploma thesis deals with the topic of segmentation of ischemic tissue in T1 weighted MRI image data using deep learning methods. The theoretical part deals with the anatomy of brain, brain imaging using MRI, available datasets for automatic segmentation of pathological brain tissue and automatic deep learning methods for segmentation of ischemic brain tissue. In the practical part the used dataset and its preprocessing, as well as the proposed deep learning methods (U-Net) and their training, are described. The models were implemented using Python. Finally, the results of the models are presented and discussed.
