    • An apparatus and associated method for detecting vulnerable plaque within a lumen defined by an intraluminal wall is described. The apparatus includes a probe having a distal portion and a proximal portion. The apparatus includes an optical waveguide extending along the probe. The optical waveguide is configured to carry optical radiation between the distal and proximal portions, and has a distal end in communication with the intraluminal wall. The apparatus includes an interferometer coupled to the optical waveguide and configured to provide an interference signal for sub-surface imaging of the intraluminal wall, and a processing module configured to provide spectroscopic information from detected intensity of light collected from the intraluminal wall.
    • 描述了一种用于检测由腔内壁限定的腔内的易损斑块的装置和相关方法。 该装置包括具有远侧部分和近端部分的探针。 该装置包括沿探针延伸的光波导。 光波导被配置为在远端部分和近端部分之间携带光辐射,并且具有与管腔内连通的远端。 该装置包括耦合到光波导并被配置为提供用于腔内壁的次表面成像的干涉信号的干涉仪,以及被配置为从从管腔内收集的光的检测强度提供光谱信息的处理模块。
