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.【課題】複数の放射線源が列状に配置されたマルチ放射線発生装置において、放射線源の位置によって被写体との距離が異なるため、照射線量にばらつきが生じる。【解決手段】放射線源２の位置に応じて、放射線源から放出される放射線量を制御する制御手段１３，１４を備え、各放射線源と被写体との距離に応じて、各放射線源の照射時間、アノード電流値などを変えることで、放射線源の位置の違いに起因する放射線量のばらつきを低減する。【選択図】図１
