Title (EN) NOISE ATTENUATION COLLIMATOR AND IMAGING CATHETER SYSTEM COMPRISING SAME
(FR) COLLIMATEUR D'ATTÉNUATION DE BRUIT ET SYSTÈME DE CATHÉTER D'IMAGERIE L'INCLUANT
(KO) 잡음 감쇠 시준기 및 이를 포함하는 영상 카테터 시스템
Abstract:
(EN) Disclosed are a collimator for reducing noise of a scanned image and an imaging catheter system comprising the same. The disclosed noise attenuation collimator comprises: a transparent tube having a diameter larger than a cladding diameter of double clad fiber, wherein a coating removal region of the double clad fiber is inserted into the transparent tube; and a first resin layer which is applied to the outside of the transparent tube and has a refractive index smaller than the refractive index of the transparent tube.
(FR) La présente invention concerne un collimateur pour réduire le bruit d'une image balayée et un système de cathéter d'imagerie l'incluant. Le collimateur d'atténuation de bruit selon l'invention comprend : un tube transparent de diamètre supérieur à celui d'un diamètre de gainage d'une fibre double gainage, où une région de retrait de revêtement de la fibre à double gainage est insérée dans le tube transparent; et une première couche de résine qui est appliquée sur l'extérieur du tube transparent et présente un indice de réfraction inférieur à l'indice de réfraction du tube transparent.
(KO) 스캔 영상의 노이즈를 감소시키는 시준기 및 이를 포함하는 영상 카테터 시스템이 개시된다. 개시된 잡음 감쇠 시준기는 더블 클래드 파이버의 코팅 제거 영역이 삽입되며, 상기 더블 클래드 파이버의 클래딩 직경보다 큰 직경의 투명 튜브; 및 상기 투명 튜브의 외부에 도포되며, 투명 튜브 굴절률보다 작은 굴절률의 제1수지층을 포함한다.
