Fig. 7.

(a) Reflectance spectra obtained from the hyperspectral data cubes of the in vivo porcine ischemic skin flap at 7 different spots. (b) Reflectance spectra acquired from the corresponding in vivo DTPs. The in vivo DTPs were generated by projecting the hyperspectral data cubes using a HIP projector. Reflectance spectra in (b) are almost identical to those in (a) at different spots, indicating that a DTP is able to reproduce the spectral characteristics of the original ischemic skin flap with high fidelity.
