Accelerated Non-contrast-enhanced Morphological and Functional Magnetic Resonance Angiography Abstract Cardiovascular diseases such as stroke, stenosis, peripheral or renal artery disease require accurate angiographic visualization techniques both for diagnosis and treatment planning. Beside ...

Magnetic Resonance Imaging for Percutaneous Interventions Abstract The fundamental motivation for all percutaneous interventions is to improve patient care by reducing the invasiveness of the procedure. An increasing number of percutaneous interventions from biopsies, targeted drug delivery t...

Automatic Classification of Cerebral Gliomas by Means of Quantitative Emission Tomography and Multimodal Imaging Abstract Cerebral gliomas represent a common type of cancer of the human brain with many tumor grades which express a huge diversity in growth characteristics and have a highly var...

C-arm Computed Tomography with Extended Axial Field-of-View Abstract C-arm computed tomography (CT) is an innovative imaging technique in the interventional room that enables a C-arm system to generate 3D images like a CT system. Clinical re- ports demonstrate that this technique can help red...

Ansichtenauswahl für die 3-D-Rekonstruktion statischer Szenen Abstract The problem of 3-D reconstruction is one of the main topics in computer vision. If certain imaging parameters can be modified to improve the 3-D reconstruction result, the question how to select this parameters belongs to ...

Automated Evaluation of Three Dimensional Ultrasonic Datasets Abstract Non-destructive testing has become necessary to ensure the quality of materials and components either in-service or at the production stage. This requires the use of a rapid, robust and reliable testing technique...

Computerized Automatic Modeling of Medical Prostheses Abstract In this thesis we study artificial intelligence methods, rule-based expert systems in particular, for the task of automatically designing customized medical prostheses. Here, the term design denotes the shaping or modeling of the ...

Physics-based and Statistical Features for Image Forensics Abstract The objective of blind image forensics is to determine whether an image is authentic or captured with a particular device. In contrast to other security-related fields, like watermarking, it is assumed that no supporting patte...

Efficient and Trainable Detection and Classification of Radio Signals Abstract The strong need for robust and efficient radio signal detection and classification can be found both in civil and non-civil applications. Most of the current state-of-the-art systems are based on a separated versio...

Interactive Approaches to Video Lecture Assessment Abstract A growing number of universities and other educational institutions record videos of regularly scheduled classes and lectures to provide students with additional resources for their study. However, the video alone is not necessarily ...
