Mathematical Modeling and Analysis
The propagation of light through human tissue is described by the linear transport equation. This equation models the behavior exhibited by photons (quantum-sized particles of light) when streaming through a domain filled by the nuclei of a background medium. In my work, least-squares principles are employed to solve this equation, which results in knowledge of the photon distribution within the physical domain. An example of such a domain is human tissue. The usefulness of this method is apparent in biomedical optical imaging where non-invasive techniques, based on this equation, are used to detect tissue abnormalities.
