ROCHESTER (AP) -- After spearheading an epic, 18-hour documentary on the Vietnam War, acclaimed filmmaker Ken Burns has turned to more personal subject matter - one that knows him very intimately, too.

Burns tackles the famed Mayo Clinic in his next film, exploring the history of the innovative Rochester, Minnesota-based hospital that has been dubbed ``The Miracle in a Cornfield.''


Luminaries such as the Dalai Lama - and Burns - have been treated at the hospital. The first time he went, Burns says he was immediately impressed by the level and detail of his medical care.

The result is the two-hour documentary ``The Mayo Clinic: Faith, Hope, Science,'' which airs Tuesday on PBS. Burns calls the hospital's tale ``a quintessentially American story.''
