Integrated IVOCT-NIRF. (a) A typical IVOCT-NIRF system schematic. WDM: wavelength-division multiplexing. DCF: double-clad fiber. PMT: photomultiplier tube. CW: continuous wavelength. (b) Representative IVOCT (inner) and NIRF (outer) image of a rabbit aorta in which high NIRF signals, denoted by the white arrows, are observed, indicative of macrophage aggregation. In the OCT image, thickening intimal is noted, which is supported by the histological reading. (c) The corresponding histology of (b). Scale bars: 1 mm.
