PROBLEM TO BE SOLVED: To equalize S/N ratios of radiological images with two parallaxes.SOLUTION: An angle &theta between one of two radiographing directions and a direction perpendicular to a detection plane 15a of a radiation detector 15 is set to be larger than an angle &theta" between the other radiographing direction and the direction perpendicular to the detection plane of the radiation detector. Each radiation amount IE1, IE2 is controlled so that each of the radiation amount IE1, IE2 reaching the radiation detector 15 from the one radiographing direction is equal to the radiation amount reaching the radiation detector 15 from the other radiographing direction.COPYRIGHT: (C)2012,JPO&INPIT【課題】2つの視差を有する放射線画像のS/Nを等しくする。【解決手段】2つの撮影方向のうち、一方の撮影方向と放射線検出器15の検出面15aに直交する方向とのなす角度θ’が、他方の撮影方向と直交する方向とのなす角度θ‘よりも大きくし、一方および他方の撮影方向から放射線検出器15に到達する各放射線量EE1、EE2が等しくなるように、各放射線量IE1、IE2を制御する。【選択図】図6
