Mimicking Multimodal Contrast with Vertex Component Analysis of Hyperspectral CARS Images

Figure 2

(a) Multimodal image of an atherosclerotic rabbit aorta sample where SHG is shown in blue, TPEF is shown in green, and CARS at 2850 cm⁻¹ is shown in red. (b) Grayscale image of the 2850 cm⁻¹ CARS channel shown as red in (a). The spectra on the right are representative spectra from two individual bright (tissue) and dark (background) pixels in the image. Scale Bar: 30 μm.
