A series of recorded nonlinear spectral images excited by a broad range of laser wavelengths （730- 910 nm） are used to identify five components in the native rabbit aortic wall, including nicotinamide adenine dinucleotide （NADH）, elastic fiber, flavin, porphyrin derivatives, and collagen. Integrating multichannel subsequent detection imaging technique, the high-resolution, high contrast images of collagen and elastic fiber in the aortic wall are obtained. Our results demonstrate that this method can yield complementary biochemical and morphological information about aortic tissues, which have the potential to determine the tissue pathology associated with mechanical properties of aortic wall and to evaluate the phaxmacodynamical studies of vessels.展开更多
