Doctors at Duke University in North Carolina are the first in the world to use a new machine called the Novalis TX. It delivers radiation to tumors with amazing accuracy while minimizing damage to healthy tissue.

Doctors say the new machine emits a higher dose of radiation so they can get better control of tumors and complex lesions.

Treatments can be done in less than an hour, and patients say they don't feel any pain.
