Paper Abstract

There has been much evidence to suggest that diseased tissue is spectrally different from healthy tissue. Clinical endoscopy often results in fairly accurate diagnosis based on observed spectra (color), texture, and shapes of lesions. Conventional spectrometers lack the ability to coordinate adequate sampling of diseased verses healthy tissue to make a practical analytical tool. A video pixel spectrometer was developed which captures the spectra of a complete line of pixels within an image simultaneously. A color image of the suspicious tissue is continuously displayed which identifies a line through the image. This line represents the line of pixels which pass in to the spectrometer and is usually positioned to pass through the lesions. The spectrometer output spectrally disperses every pixel along the line simultaneously, resulting in the capture of the spectra of hundreds of pixels within the lesion and the surrounding tissue. The data can then be processed and correlated with shape and texture data for statistical classification of benign verses healthy tissue. This instrument was designed to couple to a variety of medical imaging instruments such as endoscopes, fundus cameras, macroscopic optics for dermatology, and microscopes.
