C. Seeing Things In A Different Light

Narrator: This is Science Today. Researchers at the Lawrence Livermore National Laboratory are working to improve endoscopic surgery. Physicist Lee Haddad says often times, these procedures are marred by lots of glare.

Haddad: If you look at any of the tapes of these procedures, you see lots of saturated spots in the image and glare and even streaking sometimes. That really impedes the ability of the surgeon to see what they're doing.

Narrator: Haddad and his colleague Robert Van Vorhis are working with advanced optical and digital imaging to improve visualization in endoscopic surgery.

Haddad: The first optical solution that we're trying to apply is you can think of it almost like sunglasses for your endoscope. About 80 percent of the problem is in lighting. How you illuminate the subject and so, that's basically the area that we're addressing.

Narrator: Haddad says they'll also address cost effectiveness.

Haddad: That's one of the reasons we're excited about this, because we have a chance to make a big difference without huge cost increase.

Narrator: For Science Today, I'm Larissa Branin.
