Optical technique whereby computerized images are produced from photons reflected back from light passing through tissue, with each tissue creating a unique spectral signature. Present studies indicate accuracy is limited to depths of 4 mm, but represents a significant improvement in diagnostic capability over surface viewing as is presently obtained in standard endoscopies. Future studies may include the use of dyes and fluorescent markers for visualization and differentiation between benign and malignant tissues. Source: Reuters as reported by Stanford University.
An in vivo imaging technique that sends out femtosecond infrared pulses and uses optical interference to sense reflections from tissue inhomogeneities.
A method of imaging that, in ophthalmology, uses light waves to provide cross-sectional views of interior eye structures. Also known as OCT.
