1. Optical Techniques for Breast Cancer Margin Assessment
Cancer margin assessment is key to improving the success rate of Breast Conservation Surgery (BCS). Different optical techniques such as transmission-based NIR, diffuse reflectance-based NIR, time-domain NIR, linear and circular polarization-based polarimetric tools can be used with varying efficacy to differentiate cancer from adjacent normal tissues.
2. Multispectral polarization-sensitive Intraoral Cancer Probe for Low-Resource Settings
Currently, the visual inspection by the clinician in the primary health center is inadequate for accurately diagnosing the type and stage of oral cancer. Using multispectral polarization-sensitive imaging, that selectively excites the intraoral cavity with different wavelengths based on the absorption peaks of HbO2 and Hb can help in characterizing the tissue. A portable and affordable intraoral cavity probe can be used in the primary health center which can potentially aid the clinician in improving the efficacy of oral cancer diagnosis.
