Corneal-tissue water content is critical parameter in diagnosis of cornea-related conditions and diseases. Currently, the methods to evaluate water content are very limited, may be invasive, and are often based on subjective evaluation by the physician. AGRUM aims at developing millimeter- and submillimeter-wave imaging technology for corneal diagnosis. The new technology will be integrated with the existing corneal diagnosis methods so as to yield combined information across vast spectral range. Also, AGRUM aims at developing new electromagnetic models for cornea that are more detailed and allow accurate inversing of the medically relevant parameters.
