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 continuous random medium and mass fractal. A fractal dimension can be quantified from scattering measurements such as enhanced backscattering spectroscopy and provides an exciting prospect for use as a marker for disease including assessment of cancer risk through field carcinogenesis.
