Abstract

Time-resolved polarization kinetics of near infrared spectral wing (SW) emission from human cancerous and normal prostate tissues was investigated. The intensity of spectral wing emission from the cancerous tissue was found to be stronger than that from the normal tissue, and the decay time of SW emission from the cancerous prostate tissue was found shorter than the normal prostate tissue. These differences can be attributed to increase of cell density during the evolution of tumor. The difference in intensities of the SW emission from cancerous and normal prostate tissues was used to image and identify cancerous areas from the surrounding normal prostate tissue.
