Three-dimensional interactive virtual endoscopy
Virtual endoscopy is a new development of diagnostic imaging, covering a wide range of potential clinical applications. This paper introduced a system framework for virtual endoscopy. Our research efforts concentrated on mesh smoothing, automated centerline extraction and view-dependent level-of-detail rendering techniques. First, the fairing surface was obtained by smoothing the normal vectors...
متن کاملAn Interactive Virtual Endoscopy Tool
In this paper, we present the design and implementation of a 3D Virtual Endoscopy system for facilitating diagnostic and surgical planning phases of endoscopic procedures. Our system allows the user to interactively explore the internal surface of a 3D patient-specific anatomical model and to create and update a fly-through trajectory through the model to simulate endoscopy. We also present an ...
متن کاملVisualization Techniques for Virtual Endoscopy Visualization Techniques for Virtual Endoscopy
Virtual Endoscopy is a technique to explore hollow organs and anatomical cavities using 3D medical imaging and computer graphics. Virtual Endoscopy turns out to be a promising technique to improve, or even in some procedures substitute, real endoscopy. A real endoscopy is invasive and usually implies some risk for the patient. In the last decades, much research has been done in this field. This...
متن کاملQuantitative Endoscopy - Virtual Interaction
Minimally invasive surgical interventions (MIS) using monocular optics lead to the loss of 3D depth perception due to the 2D visualization. Thus the surgeon must estimate the pose of 3D objects in the surgical scene solely based on his experience. Especially for residents this is very difficult due to the lack of this experience. This may lead to longer surgeries thus to more cost and higher mo...
متن کاملWeb-based virtual endoscopy.
A web-based application for computed tomography (CT) image analysis and visualization of the bronchial airways is presented in the paper. The technique used in this application provides a noninvasive way to examine the interior of the bronchial tubes. Many different properties of the tubes such as presence of the foreign objects or structure abnormalities of the tubes can be detected this way. ...
