Paper Abstract

Esophageal cancer patients often present a highly inflamed esophagus at the time of treatment by photodynamic therapy. Immediately after treatment, the inflamed vessels have been shut down and the esophagus presents a white surface. Optoacoustic imaging via an optical fiber device can provide a depth profile of the blanching of inflammation. Such a profile may be an indicator of the depth of treatment achieved by the PDT. Our progress toward developing this diagnostic for use in our clinical PDT treatments of esophageal cancer patients is presented.
