Computer-aided Diagnosis for Magnetically Guided Capsule Endoscopy Digestive diseases and disorders are diverse with some being more common and of short duration, whereas others may be life threatening if left untreated. They are among the most common problems that people are afflicted with at l...

C-arm Cone-Beam Computed Tomography Reconstruction for Knee Imaging under Weight-Bearing Conditions Medical imaging is essential for the assessment of osteoarthritis and the overall knee health. For that purpose, radiographs of the knees of standing patients are acquired commonly. These suffer,...

Epipolar Consistency in Transmission Imaging Two X-ray projection images of a rigid object may have different points of view, yet redundant information can be identified in such images. Not unlike a checksum, these occur naturally in the data and are known as consistency conditions. Real acquisi...

Single photon emission computed tomography (SPECT) is a medical imaging modality used to visualize the distribution of radioactive tracers in a patient's body. While SPECT's utility as a diagnostic modality has long been established, its use for planning and managing nuclear medicine therapies has ...

Non-invasive imaging methods are capable of revealing content that is not visible with the naked eye. In this thesis, we present solutions for three common areas of application: digitization of cultural heritage, medicine, and quality assessment. The success story of those approaches is further...

Real-time Respiratory Motion Analysis Using GPU-accelerated Range Imaging Abstract Respiratory motion analysis and management are crucial issues for a plurality of medical applications. Of particular scientific concern are methods that allow to analyze the patient’s breathing in a non-invasi...

Robust Personalization of Cardiac Computational Models Abstract Heart failure (HF) is a major cause of morbidity and mortality in the Western world, yet early diagnosis and treatment remain a major challenge. As computational cardiac models are becoming more mature, they are slowly evolving...

Respiratory Motion Compensation in X-Ray Fluoroscopy Abstract Fluoroscopy is a common imaging modality in medicine for guidance of minimally invasive interventions due to its high temporal and spatial resolution and the good visibility of interventional devices and bones. To counteract its...

3-D Imaging of Coronary Vessels Using C-arm CT Abstract Cardiovascular disease has become the number one cause of death worldwide. For the diagnosis and therapy of coronary artery disease, interventional C-arm-based fluoroscopy is animaging method of choice.  While these C-arm sys...

Artificial Intelligence for Medical Image Understanding Abstract Robust and fast detection and segmentation of anatomical structures in medical image data represents an important component of medical image analysis technologies. Current solutions for this problem are nowadays based on machin...
