Advances in the simulation of light-tissue interactions in biomedical engineering

No prior work had resolved the full complexity of light transport within heterogeneous biological environments. Researchers often struggled to balance computational speed with the high accuracy required for clinical diagnostics. Prior research has shown that traditional models frequently oversimplified photon scattering events. That uncertainty drove the need for more robust mathematical frameworks. Scientists previously relied on static approximations that failed to capture dynamic tissue changes.
