Diagnostic System for Intestinal Motility Disfunctions Using Video Capsule Endoscopy
نویسندگان
چکیده
Wireless Video Capsule Endoscopy is a clinical technique consisting of the analysis of images from the intestine which are provided by an ingestible device with a camera attached to it. In this paper we propose an automatic system to diagnose severe intestinal motility disfunctions using the video endoscopy data. The system is based on the application of computer vision techniques within a machine learning framework in order to obtain the characterization of diverse motility events from video sequences. We present experimental results that demonstrate the effectiveness of the proposed system and compare them with the ground-truth provided by the gastroenterologists.

Generic Feature Learning for Wireless Capsule Endoscopy Analysis
The interpretation and analysis of wireless capsule endoscopy (WCE) recordings is a complex task which requires sophisticated computer aided decision (CAD) systems to help physicians with video screening and, finally, with the diagnosis. Most CAD systems used in capsule endoscopy share a common system design, but use very different image and video representations. As a result, each time a new c...
متن کاملIntestinal Obstruction by Capsule Endoscopy in a Patient With Radiation Enteritis
BACKGROUND Video capsule endoscopy is in widespread use as a diagnostic modality. Although capsule endoscopy is generally considered safe, several prior reports have documented capsules' failure to progress through narrowed areas of intestine. Symptomatic retention and obstruction by capsule endoscopy have not yet been reported in the setting of radiation enteritis. METHODS We report a case o...
متن کاملVideo capsule endoscopy in small-bowel malignancy: a multicenter Belgian study.
BACKGROUND AND STUDY AIMS Early diagnosis of small-bowel tumors is crucial for therapy. Video capsule endoscopy has improved the diagnosis of small-bowel diseases, but data concerning the role of this technique in detecting small-bowel malignancy are scarce. The aim of this paper was to review all capsule endoscopy findings at Belgian hospitals, in order to evaluate the diagnostic yield of caps...
متن کاملA Semi-supervised Learning Method for Motility Disease Diagnostic
This work tackles the problem of learning a robust classification function from a very small sample set when a related but unlabeled data set is provided. To this end we define a new semi-supervised method that is based on a stability criterion. We successfully apply our proposal in the specific case of automatic diagnosis of intestinal motility disease using video capsule endoscopy.
متن کاملIdentification of Intestinal Motility Events of Capsule Endoscopy Video Analysis
Purpose: To develop a system for assisting the analysis of capsuleendoscopy (CE) video data and identifying sequences of frames related to small intestine motility. Material and Methods: Six videos were analyzed and labelled manually by an expert, indicating the events of contractions. For addressing the imbalanced recognition task of small intestinal contractions we employed an efficient two-l...
