PROBLEM TO BE SOLVED: To solve the following problem: in a multi-source radiation generator in which a plurality of radiation sources are arranged in a row shape, the distance between a radiation source and a subject varies depending on the position of the radiation source, causing variation in the exposure dose.SOLUTION: A multi-source radiation generator, comprising control means 13, 14 which control a dose of radiation emitted from each of the radiation sources 2 depending on the position of the radiation source, reduces variation in a radiation dose resulting from differences in positions of the radiation sources by changing the irradiation time, anode current value, etc. of each radiation sources depending on the distance from the radiation sources to a subject. |
