Title: (EN) Photoacoustic catheter and imaging system using same
(ZH) 光声导管和使用该光声导管的成像系统
Abstract: front page image
(EN) A photoacoustic catheter includes an elongated catheter body and a housing positioned near a distal end of the elongated catheter body. A length of multimode fiber extends through the elongated catheter body and has a distal end that is beveled at about 45 degree relative to a longitudinal axis of the multimode fiber and is positioned in the housing. An ultrasonic transducer, electrically connected to an electrical wire extending along the elongated catheter body, is positioned within the housing. A mirror element is also positioned within the housing and includes a mirror surface beveled at about 45 degree relative to the longitudinal axis of the multimode fiber. The catheter is operable to deliver an optical wave through the multimode fiber and to deliver an ultrasonic wave collinearly from the housing and out of an aperture of th e housing to obtain optical data and ultrasonic data within a mammalian luminal organ.
(ZH) 光声导管包括细长导管本体和布置在细长导管本体的远端部附近的外壳。一段多模纤维延伸通过细长导管本体并且具有远端部,该远端部相对于多模纤维的纵向轴线以大约45°成斜面并且布置在外壳中。电连接到沿细长导管本体延伸的电线的超声换能器被布置在外壳内。反射镜元件也被布置在外壳内并且包括反射镜表面,该反射镜表面相对于多模纤维的纵向轴线以大约45°成斜面。该导管可操作用于将光波输送过多模纤维并且从外壳并且离开外壳的孔口共线地输送超声波以获得哺乳动物腔器官内的光数据和超声数据。
