Abstract

Hyperspectral imaging (HSI) is a chemical imaging modality with spectroscopic information. This technique was often used in agricultural or pharmaceutical industries. But there have been a few reports for clinical medical applications. In near-infrared (NIR) wavelength region, the significant absorption peaks are often observed by the overtone of midinfrared molecular vibration. In addition, NIR light has a high penetration because of low scattering and less absorption by water or protein. In this study, we constructed the NIR-HSI system and the high-contrast subcutaneous adipose tissue imaging was conducted in-vitro. In the absorption spectra which are obtained by our NIR-HSI system, the characteristic absorption bands were observed around 1200 nm and 1700 nm. In the processed images using these wavelength bands, subcutaneous adipose tissue was observed through a skin. In a hyperspectral image by another processing using all wavelengths, a high-contrast image of subcutaneous adipose tissue is also obtained. NIR-HSI system is a powerful diagnostic technique for adipose tissues distribution and their morphological change on/inside a tissue.
