20 June 2013 Hyperspectral angular domain imaging for ex-vivo breast tumor detection
Author Affiliations +
An angular domain spectroscopic imaging system was built and validated using fresh ex vivo breast tissue samples (~ 2 mm thick). The hyperspectral system consisted of a halogen lamp, collimation optics, scanning stage with controller, a silicon micro-machined micro-channel array, and a pushbroom spectral imager. As a proof of concept, spectral data cubes acquired from tissue samples were input into principal component analysis and Mahalanobis discriminant analysis to differentiate between spectral signatures of breast tumor and normal tissue. It is proposed that the results from training sets can be used to construct a set of classifiers to enable tumor detection in samples representative of the surgical margins.
