Abstract
A method and system for identifying tissue types is provided that utilizes Raman scattered light in the high wavenumber region (HWN) of Raman spectrum. The method includes: a) interrogating a tissue specimen with at least one wavelength of light, the wavelength of light operable to produce Raman scattered light in a HWN region of Raman spectrum from the tissue specimen; b) producing signal data representative of the Raman scattering, the signal data relating signal intensity as a function of wavenumber within the HWN region; c) fitting a curve to a portion of the signal data attributable to a HWN peak within the signal data, for a plurality of different HWN peaks; d) determining a plurality of characteristics of each fitted curve; and e) determining a tissue type using the determined characteristics and stored collective data representative of fitted peaks in the HWN region of a plurality of different tissue types.
