To improve accuracy in diagnosis of retinal disease, ORNL researchers invented a method for assigning a confidence metric to computer-aided optic disc analysis. The physical condition of the optic disk determines the presence of various ophthalmic pathologies, including glaucoma and diabetic retinopathy. Unfortunately, localization of the optic disk and detection of its boundaries on the retinal i…

Biomedical optics is an emerging field with enormous potential to diagnose and treat diseases safely and economically. To determine the optical properties of tissue, ORNL researchers invented a new method, apparatus, and software. This invention meets the industry s need for a standardized optical property measurement system that provides accurate sample characterization and does not require costl…
