Abstract
A multi-source radiation generator in which plural radiation sources are arranged in series includes a control unit that controls a dose of radiation emitted from each of the radiation sources depending on positions of the radiation sources, and reduces variation in a radiation dose resulting from differences in positions of the radiation sources by changing an irradiation time, an anodic current value of each of the radiation sources depending on a distance from each of the radiation sources to a subject.
