Spectroscopic methods, including Raman spectroscopy, are ideal for the non-invasive imaging of tumors. Spatially resolved versions of the techniques can be used to profile the full tumor site and the spectral information provided at each imaging point can then be decomposed to provide chemical information on the local region.
