Abstract
Techniques and devices for diagnosing tissue via hyperspectral imaging are presented. A three dimensional "image" where one dimension contains spectral information is formed from a region of interest. The spectral content of the image can be analyzed on a pixel-by-pixel basis to determine the presence of certain matter and the spatial extend thereof The techniques are non-invasive and do not require introduction of agents typically required to facilitate interaction with illumination sources.
