Fusion Imaging for EVAR with Mobile C-arm

Camera Augmented Mobile C-arm

EVAR Guided by 3D Image Fusion and CO2 DSA: A New Imaging Combination for Patients With Renal Insufficiency.

PURPOSE To present a new combination of imaging techniques that helps reduce the use of iodinated contrast during endovascular aneurysm repair (EVAR) procedures in patients with renal insufficiency. TECHNIQUE Relevant anatomical structures are marked in the preprocedure computed tomography (CT) angiogram. A 3D-3D image fusion between the preprocedure CT and an intraprocedure cone-beam CT is p...

Respiratory Motion Compensation for C-Arm CT Liver Imaging

In C-arm CT 3-D liver imaging, breathing leads to motion artifacts due to the relatively long acquisition time. Often, even with breath-holding residual respiratory motion can be observed. These artifacts manifest in blurring and interfere clinical investigations such as liver tissue imaging. For 3-D medical image reconstruction a respiratory motion estimation and compensation is required. In t...

Fusion of Intracardiac Ultrasound with 3D Cardiac C-Arm CT from Animal Data for Electrophysiology

In Electrophysiology catheter ablation is an established treatment for cardiac arrhythmias. Nevertheless, complicated ablation procedures such as Pulmonary vein isolation for atrial fibrillation treatment are difficult to learn. This can be improved by a better integration of the image modalities available today and in the future Electrophysiology lab. In this paper, we present a method to regi...

Efficient Segmentation of 3D Fluoroscopic Datasets from Mobile C-arm

The emerging mobile fluoroscopic 3D technology linked with a navigation system combines the advantages of CT-based and C-arm-based navigation. The intra-operative, automatic segmentation of 3D fluoroscopy datasets enables the combined visualization of surgical instruments and anatomical structures for enhanced planning, surgical eye-navigation and landmark digitization. We performed a thorough ...
