摘要

Hyperspectral imaging combines high spectral and spatial resolution in one modality. This imaging technique is a promising tool for objective medical diagnostics. However, to be attractive in a clinical setting the technique needs to be fast and accurate. Hyperspectral imaging can be used to analyze the chemical composition of tissue using spectroscopic methods. and is thus useful as a general purpose diagnostic tool. In this study, we combine an analytic diffusion model for photon transport with real-time analysis of hyperspectral images. This is achieved by invert ing and parallelizing the photon transport model on a GPU to yield optical parameters from diffuse reflectance spectra. The resulting inversion chain was found to output the results in real-time. The inverse approach was found to characterize the relative differences in the optical properties. The presented approach is a proof of principle, necessary for developing a future real-lime diagnostic system using hyperspectral imaging.
