Optical Parameters of Brain Tissue and Tumors of the Brain in the Spectral Range 200–900 nm
The sometimes distinct differences in color between normal brain tissue and brain tumors raise the question whether choosing a suitable wavelength makes it possible to achieve selective damage of brain tumors by laser irradiation in neurosurgery. The present preliminary report contains data of the reflectance and transmittance of human brain tissue and brain tumors. The measurements were obtained with a two-beam spectral photometer with an integrating sphere serving as measuring instrument (1,2).
