Optical Detection of Cancers

Stokes scattering matrix for human skin

“…Images acquired with polarized light can isolate such interfacereflected light [16] and help to explore the surface details with better contrast. Such images of skin lesions have been analyzed to detect early stages of skin cancer [17,18] as well as other dermatological conditions [19].…”

Screening for oral cancers—Which method is most effective?

“…The diagnostic interpretation of the tissue sample has been shown to vary among pathologists, and the pathologic criteria for the identification of precancerous lesions are not well defined. 11 In addition, early precancerous changes are frequently undetectable by conventional visual inspection, leading to missed opportunities for diagnosis. Optical technologies show the potential to provide real-time assessment through a minimally invasive route, eliminating lengthy waiting time and the need for tissue biopsy.…”
