Detecting skin cancers with lasers June 11, 2007
Posted by Adi Narayan in Lasers, Medical imaging.trackback
Folks at Duke Uni have made a system that fires low power lasers on the surface of the skin and checks for telltale signs of Skin cancer. It fires out a series of beams and finds the concentration of haemoglobin and melanin – two chemicals inherently present in the skin. The relative concentrations can give an idea if cancerouns growth is happening or if its just some simple wart or something.
- It works with femtosecond lasers and employs pulse shaping >> thats going to be pretty expensive.
- The setup is really BIG (look at the article below), and they got some really shrinking to do..

And a link to an article I wrote about a Purdue Uni team that used holograms to find how anti-cancer drugs are faring..
