Title (EN) SYSTEM AND METHOD FOR ACQUIRING SLICE IMAGE IN BLOOD VESSEL USING OPTICAL COHERENCE TOMOGRAPHY DEVICE AND IMAGING CATHETER
(FR) SYSTÈME ET PROCÉDÉ D'ACQUISITION D'IMAGE EN COUPE DANS UN VAISSEAU SANGUIN AVEC UN DISPOSITIF DE TOMOGRAPHIE PAR COHÉRENCE OPTIQUE ET UN CATHÉTER D'IMAGERIE

Abstract: front page image
(EN)The present invention provides a system and a method for acquiring a slice image in a blood vessel using an optical coherence tomography (OCT) device and an imaging catheter, the system for acquiring a slice image in a blood vessel comprising: a micro-catheter inserted into a blood vessel so as to assist the forward movement of another catheter; a micro-wire for guiding the forward movement of the catheter connected by being inserted into the blood vessel; an OCT imaging catheter including an optical fiber, which is connected to the micro-wire so as to be inserted into the blood vessel according to the forward movement of the micro-wire; and an OCT module for acquiring reflection information on light irradiated by the OCT imaging catheter, so as to convert the same into a slice image in the blood vessel. Thus, the insertion and the forward movement of the micro-catheter, the micro-wire, and the OCT imaging catheter or the like are controlled so as to increase accessibility of the catheters to the lesion region even in a narrow and meandering blood vessel such as a cerebrovascular system.
(FR)La présente invention concerne un système et un procédé d'acquisition d'une image en coupe dans un vaisseau sanguin en utilisant un dispositif de tomographie par cohérence optique (OCT) et un cathéter d'imagerie, le système d'acquisition d'une image en coupe dans un vaisseau sanguin comprenant : un micro-cathéter inséré dans un vaisseau sanguin pour aider le mouvement vers l'avant d'un autre cathéter ; un micro-fil métallique pour guider le mouvement vers l'avant du cathéter raccordé en étant inséré dans le vaisseau sanguin ; un cathéter d'imagerie par OCT comprenant une fibre optique, qui est raccordé au micro-fil métallique pour être inséré dans le vaisseau sanguin selon le mouvement vers l'avant du micro-fil métallique ; et un module OCT d'acquisition des informations de réflexion relatives à la lumière irradiée par le cathéter d'imagerie par OCT, pour convertir celle-ci en une image en coupe dans le vaisseau sanguin. Ainsi, l'insertion et le mouvement de progression du micro-cathéter, du micro-fil métallique et du cathéter d'imagerie par OCT ou équivalents sont commandés pour augmenter l'accessibilité des cathéters à la région de lésion même dans un vaisseau sanguin étroit et tortueux, par exemple dans un système cérébrovasculaire.
(KO)본 발명에서 제안하고 있는 광 간섭 단층촬영기 및 이미징 카테터를 이용한 혈관 내 단면 영상 획득 시스템 및 방법에 따르면, 혈관 내로 삽입되어 다른 카테터의 전진을 도와주는 마이크로 카테터, 혈관 내로 삽입되어 연결된 카테터의 전진 방향을 가이드 하는 마이크로 와이어, 마이크로 와이어와 연결되어 마이크로 와이어의 전진 방향을 따라 혈관 내로 삽입되는 광섬유를 포함하는 OCT(Optical Coherence Tomography)용 이미징 카테터, 및 OCT(Optical Coherence Tomography)용 이미징 카테터가 조사한 광의 반사 정보를 획득하여 혈관 내 단면 영상으로 변환하는 광 간섭 단층촬영 모듈을 포함하여 혈관 내 단면 영상 획득 시스템을 구성하고, 마이크로 카테터, 마이크로 와이어 및 OCT(Optical Coherence Tomography)용 이미징 카테터 등의 삽입 및 전진을 제어하여, 뇌혈관과 같은 좁고 구불구불한 혈관에서도 상기 카테터들의 병변 부위 접근성을 높일 수 있다.
