Title
(EN) METHOD AND APPARATUS FOR DETECTING BARRETT'S METAPLASIA OF THE ESOPHAGUS
(FR) PROCEDE ET APPAREIL POUR DETECTER LA METAPLASIE DE BARRETT DE L'×SOPHAGE
Abstract
(EN)
A system for detecting Barrett's metaplasia utilizes an illumination and imaging probe (32) at the end of a catheter (34). The probe (32) illuminates the wall of the esophagus and returns reflected light to be processed to provide a visual indication of the color of the esophageal wall. The position of the probe along the length of the esophagus is also measured to allow a medical practitioner to determine the location of the transition from the pink stomach lining to the white esophageal lining.
(FR)
L'invention concerne un système pour détecter la métaplasie de Barrett. Ce système utilise un éclairage et une sonde d'imagerie (32) à l'extrémité d'un cathéter (34). La sonde (32) éclaire la paroi de l'÷sophage et renvoie la lumière réfléchie à traiter et fournit une indication visuelle de la couleur de la paroi de l'÷sophage. La position de la sonde sur la longueur de l'÷sophage est également mesurée pour permettre au médecin de déterminer l'emplacement de la transition entre la muqueuse rose de l'estomac et la muqueuse blanche de l'÷sophage.
