Treating cancer with light
Date:10/18/2010

ize the variability among subjects and within the lesions themselves. The process took 5-10 seconds and produced images with a resolution of 30 microns, revealing spatially resolved maps of the optical properties of the lesions, tissue oxygenation and quantitative distribution of the photosensitizing drug.

Saager and colleagues hope that this imaging technique will provide a better map for targeting and optimizing photodynamic therapy for basal cell carcinoma, the most common type of skin cancer. The next step for their ongoing experiment will be to enable the therapeutic aspects of the instrument and monitor the tissue dynamics during PDT treatment regimens.
