Abstract
(EN)
A catheter system for optical coherence tomography includes an elongate catheter body, an optical fiber in the elongate catheter body, and an anamorphic lens assembly coupled with a distal end of the optical fiber. The optical fiber and the lens assembly are together configured to provide a common path for optical radiation reflected from a target and from a reference interface between the distal end of the optical fiber and the lens assembly.

(FR)
La présente invention concerne un système de cathéter pour tomographie par cohérence optique qui comprend un corps de cathéter allongé, une fibre optique dans le corps du cathéter allongé et un ensemble de lentilles anamorphosantes couplé à une extrémité distale de la fibre optique. La fibre optique et l'ensemble de lentilles sont configurés ensemble pour former un trajet commun pour un rayonnement optique réfléchi par une cible et par une interface de référence entre l'extrémité distale de la fibre optique et l'ensemble de lentilles.
