TaʼrifPhotodynamic therapy.jpg |
Public domain image from cancer.gov http://visualsonline.cancer.gov/details.cfm?imageid=2340. Shown is close up of surgeons' hands in an operating room with a "beam of light" traveling along fiber optics for photodynamic therapy. Its source is a laser beam which is split at two different stages to create the proper "therapeutic wavelength". A patient would be given a photo sensitive drug (photofrin) containing cancer killing substances which are absorbed by cancer cells. During the surgery, the light beam is positioned at the tumor site, which then activates the drug that kills the cancer cells, thus photodynamic therapy (PDT). In addition to the implicit public domain status provided as a work of the United States Government, the en:National Cancer Institute has also explicitly licensed this photo into the public domain: http://visualsonline.cancer.gov/about.cfm |
