Optical interactions with biological tissue provide powerful tools for study, diagnosis, and treatment of disease. Optical scattering in tissue is one important interaction that is often considered a problem that limits imaging depth and degrades image quality. However, scattering can also be used to assess structural alterations in tissue. For example, tissue may be modeled as a mass fractal with a fractal dimension can be quantified from scattering measurements such as enhanced backscattering spectroscopy and used as a marker for disease including cancer risk assessment.
