Three-Dimensional Endoscopy
This contribution presents a robust estimation technique for computation of camera motion and 3D reconstruction of a scene from an endoscopic image sequence. The technique offers new possibilities for more objective diagnoses and intervention planning. Every ordinary flexible monocular video endoscope can be used without modifications.
متن کاملNovel experimental and software methods for image reconstruction and localization in capsule endoscopy
Background and study aims Capsule endoscopy (CE) is invaluable for minimally invasive endoscopy of the gastrointestinal tract; however, several technological limitations remain including lack of reliable lesion localization. We present an approach to 3D reconstruction and localization using visual information from 2D CE images. Patients and methods Colored thumbtacks were secured in rows to...
متن کاملThree-Dimensional Image of A Communicating Uterus
Recent advances in reproductive medicine have created a demand for more accurate and safe imaging modalities before assisted reproductive treatment(ART) (1). Gradually, the important role of three-dimensional (3D) ultrasonography in the diagnosis of uterine congenital anomalies has been proved (2-4).
متن کاملCapsule Endoscopy
Since first described in 2000 [1], capsule endoscopy has established itself as a noninvasive investigative modality of the gastrointestinal tract. It is used as a first-line investigation to image a variety of diseases of the small bowel. These include common conditions, such as coeliac disease, and rare diseases, such as familial adenomatous polyposis, both discussed in detail in this special ...
متن کاملThree-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...
