Abstract
A radiation tube includes an enclosure having an opening portion, an electron source disposed inside the enclosure, a target unit configured to generate radiation by being bombarded with electrons emitted from the electron source, and a front shield disposed on the opening portion and joined to the target unit. The front shield has a slit-shaped opening that shields some of the radiation radiated from the target unit. The radiation is radiated through the opening in the shape of a fan beam.
