“…After obtaining the raw hyperspectral data of the rabbit small intestine tissue, the data must be corrected to convert the raw light intensity information into relative reflectance information [40], as shown in Equation 1: Inormλ,i,j=Irawλ,i,jIdarkλ,i,jIwhiteλ,i,jIdarkλ,i,j where Irawλ,i,j is the light intensity value of each pixel point in the raw hyperspectral data at each band. Iwhiteλ,i,j and Idarkλ,i,j are the light intensity value of each pixel of the whiteboard and dark in each waveband, respectively.…”

“…Spectral signatures could help measure tissue oxygenation, 9,10 act as indicators for tumor metabolism, 2 or detect different skin pathologies 11 . Differences in the optical properties of the skin can be indicators of cancer growths 12,13 . Monte Carlo simulations can be used in combination with spectral measurements to take into account the multilayered structure of the skin, in order to provide insight into skin tissue components 14,15 …”

“…Tomanic et al use the hyperspectral imaging and 3D optical profilometry (OP) methods to estimate quantitative physiological and morphological tissue parameters of subcutaneous murine tumor models [3]. As described by the authors, the acquired hyperspectral images are corrected with the 3D OP method and analyzed using the inverse-adding doubling method to extract tissue properties such as melanin volume fraction and oxygenation.…”
