Interventional Perfusion Imaging Using C-arm Computed Tomography: Algorithms and Clinical Evaluation Abstract A stroke is a medical emergency which requires immediate diagnosis and treatment. For several years, image-based stroke diagnosis has been assisted using perfusion computed tomography (CT) and perfusion magnetic resonance imaging (MRI). A contrast agent bolus is injected and time-resolved imaging, at typically […]Interventional Perfusion Imaging Using C-arm Computed Tomography: Algorithms and Clinical Evaluation Abstract A stroke is a medical emergency which requires immediate diagnosis and treatment.

Patient-Specific Cerebral Vessel Segmentation with Application in Hemodynamic Simulation Abstract Cerebral 3-D rotational angiography has become the state-of-the-art imaging modality in modern angio suites for diagnosis and treatment planning of cerebrovascular diseases, e. g. intracranial aneurysms. Among other reasons, it is believed that the incidence of aneurysms is due to the local prevalent hemodynamic pattern. […]Patient-Specific Cerebral Vessel Segmentation with Application in Hemodynamic Simulation Abstract Cerebral 3-D rotational angiography has become the state-of-the-art imaging modality in modern angio suites for diagnosis and treatment planning of cerebrovascular diseases, e. g. intracranial aneurysms.

Statistical Intensity Prior Models with Applications in Multimodal Image Registration Abstract Deriving algorithms that automatically align images being acquired from different sources (multimodal image registration) is a fundamental problem that is of importance to several active research areas in image analysis, computer vision, and medical imaging. In particular, the accurate estimation of deformations in multimodal […]Statistical Intensity Prior Models with Applications in Multimodal Image Registration Abstract Deriving algorithms that automatically align images being acquired from different sources (multimodal image registration) is a fundamental problem that is of importance to several active research areas in image analysis, computer vision, and medical imaging.

Optimizing Application Driven Multimodality Spatio-Temporal Emission Imaging Abstract Single Photon Emission Computed Tomography (SPECT) is a widely used nuclear medicine imaging technique with many applications in diagnosis and therapy. With the introduction of hybrid imaging systems, integrating a SPECT and a Computed Tomography (CT) system in one gantry, diagnostic accuracy of nuclear procedures has been […]Optimizing Application Driven Multimodality Spatio-Temporal Emission Imaging Abstract Single Photon Emission Computed Tomography (SPECT) is a widely used nuclear medicine imaging technique with many applications in diagnosis and therapy.

Novel Techniques for Spatial Orientation in Natural Orifice Translumenal Endoscopic Surgery (NOTES) Abstract With a novel approach abdominal surgery can be performed without skin incisions. The natural orifices provide the entry point with a following incision in stomach, colon, vagina or bladder. “Natural Orifice Translumenal Endoscopic Surgery” (NOTES) is assumed to offer significant benefits to […]Novel Techniques for Spatial Orientation in Natural Orifice Translumenal Endoscopic Surgery (NOTES) Abstract With a novel approach abdominal surgery can be performed without skin incisions.

Motion Estimation and Compensation for Interventional Cardiovascular Image Reconstruction Abstract The minimal invasive interventional treatment of cardiac diseases is of high importance in the modern society. Catheter-based procedures are becoming increasingly complex and novel tools for planning and guiding the interventions are required. In recent years intraprocedural 3-D imaging has found its way into the […]Motion Estimation and Compensation for Interventional Cardiovascular Image Reconstruction Abstract The minimal invasive interventional treatment of cardiac diseases is of high importance in the modern society.
