C. Helping Doctors See The Light

Narrator: This is Science Today. Endoscopy is a surgical procedure in which a long instrument with a lighted tip is inserted into organs such as the abdomen and intestines. While this alleviates cutting a person open, physicist Lee Haddad of the Lawrence Livermore National Laboratory says the problem with endoscopes is there's too much glare on wet surfaces.

Haddad: In an open procedure, you sort of open up the area and then you have access from all directions and you can adjust lighting and the position of the surgeon's head and his angle of visualization and everything. There's a lot of freedom there. With an endoscopic procedure, there's a lot of constraint on how you illuminate the subject and how you can visualize the subject.

Narrator: Haddad and his colleagues are using advanced digital and optical technology to reduce endoscopic glare.

Haddad: I think anybody that has to go have a surgery will be real happy if there's a good way to do it. Anything we can do to improve that or make it easier for the surgeon to do his or her job, that just helps.
