July 27, 2010
Using novel light-scattering techniques to detect certain early stage cancers, researchers can look at how light bounces off of human tissue to detect subtle changes potentially caused by cancer. The spectral image that results is like a fingerprint for disease. The technology was developed with National Science Foundation support by researchers at Northwestern University and colleagues at Evanston-Northwestern Healthcare.
