Semi-Automatic Shape Extraction from Tube-like Geometry

Although the principle of using x-rays for diagnostic imaging has been known for a long time, there is still a lot of research and improvements going on in the field. One recent addition to the neuro-vascular imaging system—used for visualizing blood vessels in the brain and guidance of interventions—is 3D rotational angiography (3D-RA). Using 3D-RA, it is possible to view the vessel tree in 3D. Traditionally, 3D information could only be obtained with dedicated tube-shaped MR and CT scanners that are not available in the intervention room. With 3DRA, the 3D images can be generated in the intervention room, without moving the patient to and from the CT scanner. Also, the spatial resolution is better than that of MR and CT scanners.
