Up to now, high resolution 2-D X-ray images are acquired with a C-arm system in standard views and the diagnosis of the cardiologist is based on the observations in the planar X-ray images. No dynamic analysis of the cardiac chambers can be performed in 3-D. In the last years, cardiac imaging in 3-D using a C-arm system becomes of more and more interest in the interventional catheter laboratory. However, cardiac motion is a challenging problem in 3-D imaging, which leads to severe imaging artifacts in the 3-D image. Therefore, the main research goal of this thesis was the visualization and extraction of dynamic and functional parameters of the cardiac chambers in 3-D using an interventional angiographic C-arm system. In this thesis, two different approaches for cardiac chamber motion-compensated reconstruction have been developed and evaluated. The first technique addresses the visualization of the left ventricle. The second motion-compensated reconstruction approach uses volume-based motion estimation algorithms for the reconstruction of two left atrium and left ventricle - to four heart chambers. Overall, the results of this thesis highly demonstrate the feasibility of dynamic and functional cardiac chamber imaging using data from an interventional angiographic C-arm system for clinical applications.\u003c\/p\u003e","brand":"Logos Verlag","offers":[{"title":"Default Title","offer_id":47020778389744,"sku":"9783832537265","price":69.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0737\/7593\/9824\/files\/9783832537265_p0.jpg?v=1763687236","url":"https:\/\/shop-qa.barnesandnoble.com\/products\/9783832537265","provider":"Barnes \u0026 Noble (DEV)","version":"1.0","type":"link"}
