Statistical Medical Image Registration with Applications in Epilepsy Diagnosis and Shape-Based Segmentation Abstract: The advances in scanner technologies over the past years and a growing number of modalities in medical imaging result in an increased amount of patient data. The physicians a...

Cardiac C-Arm Computed Tomography: Motion Estimation and Dynamic Reconstruction Abstract Generating three dimensional images of the heart during interventional procedures is a significant challenge. In addition to real-time fluoroscopy, angiographic C-arm systems can also be used to generate...

Speech of children with Cleft Lip and Palate: Automatic Assessment Abstract This work investigates the use of automatic speech processing techniques for the automatic assessment of children’s speech disorders. The target group were children with cleft lip and palate (CLP). The speech process...

Image Reconstruction from Fan-Beam and Cone-Beam Projections Abstract This thesis addresses the problem of reconstructing static objects in 2D and 3D transmission computed tomography (CT). After reviewing the classical CT reconstruction theory, we discuss and thoroughly evaluate various nove...

Accurate Cone-Beam Image Reconstruction in C-Arm Computed Tomography Abstract The goal of this thesis is the robust implementation of an accurate cone-beam image reconstruction algorithm such that it is able to process real C-arm data from a circle-plus-arc trajectory. This trajectory is co...
