Delayed fluorescence as an imaging method for effective surgical tumor removal

Caption

The signal obtained from cancerous cells was over five times stronger than that from surrounding healthy oxygenated tissues. Cancerous tissue reoxygenates slower than healthy tissue, so palpation prior to imaging amplified the contrast. After 70 seconds, tumor tissue hypoxia on the right is most clearly visible via delayed fluorescence imaging.
