Abstract
The present invention relates to a fully quantitative spectroscopy imaging instrument for wide area detection of early cancer (dysplasia). This instrument provides quantitative maps of tissue biochemistry and morphology, making it a powerful surveillance tool for objective early cancer detection. The design, construction, calibration, and diagnostics applications of this system is described with the use of physical tissue models. Measurements were conducted on a resected colon adenoma, and the system can be used for vivo imaging in the oral cavity.
