Abstract

Medical applications of orthogonal polarization spectral (OPS) imaging technology are provided. This technology provides for a high contrast image of sub-surface phenomena such as blood vessel structure, blood flow within vessels, gland structure, etc., as well as a high resolution image of the surface of solid organs. Numerous clinical (diagnostic and therapeutic), as well as research applications of this technology, in the medical and pharmaceutical fields, are discussed.
