virtual endoscopy

virtual endoscopy

computed tomographic data reconstructed in three dimensions to give information similar to that obtained with endoscopy.
The use of any imaging modality—e.g., ultrafast CT—to obtain 2-D images that are reconstructed to form 3-D images similar to the surface of a mucosal seen by endoscopy

virtual endoscopy

Imaging The use of an imaging modality–eg, ultrafast CT, to obtain 2-D images, which are reconstructed to form a 3-D image that is similar to endoscopy; VE does not obtain a biopsy. See Position.

The StealthStation ENT system provides enhanced visualization to surgeons and also offers new software and hardware innovations including Virtual Endoscopy, which provides a simulated view of sinus cavities previously inaccessible with a traditional endoscope.Virtual Endoscopy can be loaded with the patient's preoperative data to allow the surgeon to practice an individual's surgery before entering the surgical suite.
"It provides an added level of assurance and may allow for a more thorough sinus procedure." The StealthStation ENT system provides enhanced visualization to surgeons and also offers new software and hardware innovations including Virtual Endoscopy, which provides a simulated view of sinus cavities previously inaccessible with a traditional endoscope.
The basics of the various modalities used to image the larynx including x-ray, CT, MRI, xeroradiography, fluoroscopy, and PET-CT are described well elsewhere, as are the exciting technologies of virtual endoscopy and virtual dissection.
In particular, the use of multiplanar reformats and 3D volume renderings, with or without virtual endoscopy, can improve assessment of laryngeal framework fractures, arytenoid subluxation, and laryngotracheal narrowing, thereby providing helpful information for optimal management.
In previous studies, the perspective view, which yielded size differences between close and distant objects, was needed for virtual endoscopy (Kwon et al.; Shin et al., 2014), but in the present study, we compared the anterior, posterior, right, and left views of the stomach with one another, so the parallel view was appropriate (Fig.
took advantage of virtual endoscopy to analyze and track lesions [12-14], but the virtual endoscopy required extra CT or MRI scans, which increased the operation expense.
Objectives: To study the use of helical computed tomography 2-D and 3-D images, and virtual endoscopy in the evaluation of airway disease in neonates, infants and children and its value in lesion detection, characterisation and extension.
Virtual endoscopy trainings for example on a virtual reality (VR) simulator have been shown to improve the performance of VR endoscopic tasks by novice endoscopists.[sup.7] However, VR training is unable to override the impact of clinical training, although it may help shorten the learning curve during the earlier period of learning the techniques.
Other presenters spoke on capsule endoscopy, virtual endoscopy and radiological diagnosis of gastro-intestinal diseases.
CT virtual endoscopy is a post-processing tool that can aid in depicting disorders of the airways and may assist in preoperative planning.
