Title: Development of an Automatic Segmentation, Measuring, and Planning Tool for the Aorta and Aneurysms
Abstract: More and more aneurysms of the thoracic and abdominal aorta are treated minimally-invasive by implanting a stent graft inside the aorta. However, without opening the patient the clinicians rely on imaging techniques, e.g. computed tomography, magnetic resonance imaging and X-ray, in order to visualize the region of interest and for intraoperative navigation. Unfortunately not all imaging modalities are available during operation, some are only available preoperatively. In 2003 the STENT project explored the prospects of using computer aided imaging techniques for preoperative planning and intraoperative navigation. Within the project a first prototype application was developed, but due to time constraints never made it to the operating room. This project is the continuation of the 2003's STENT project and its goal is to provide the clinicians with a preoperative planning tool and an intra-operative navigation and visualization tool. Preoperativly acquired computed tomography images can be used for segmentation, visualization and metric measurement of the aorta and aneurysm. Intra operatively taken X-ray images are aligned with the CT data, thus aiding navigation by supplying a three-dimensional visualization of an anatomical detailed model, metrics and current as well as planned locations of the stent graft.
