Abstract
A radiation source includes a radiation tube having a cathode which is a cold cathode. An imaging control unit directs the radiation source to intermittently and alternately emit the first radiation having a first energy distribution and the second radiation having a second energy distribution different from the first energy distribution whenever a rotation mechanism rotates the radiation source and a radiation detector by a preset angle. The imaging control unit directs the radiation detector to output a first projection image based on the first radiation and a second projection image based on the second radiation which are obtained by the intermittent emission of the first radiation and the second radiation. An image processing unit generates a tomographic image on the basis of the first projection image and the second projection image.
