PROBLEM TO BE SOLVED: To determine whether or not to drive a radiation detector at high speed, while taking account of possibility of using the radiator detector with constant energization.SOLUTION: An X-ray imaging system 100 including an X-ray detector capable of driving at a normal driving mode and a high-speed driving mode which drives at higher speed than the normal driving mode includes: an X-ray detector control part 132 for acquiring information necessary to determine the transition of the driving modes from the current state of the X-ray detector and a driving mode transition determination part 133 for determining whether or not to transit the driving mode of the X-ray detector from the normal driving mode to the high-speed driving mode based on the acquired information necessary to determine the transition of the driving modes.COPYRIGHT: (C)2013,JPO&INPIT【課題】放射線検出器の常時通電での使用可能性を考慮しつつ、高速駆動させる又は高速駆動させない判断を実施できるようにする。【解決手段】通常駆動モードと、通常駆動モードよりも高速に駆動する高速駆動モードとの駆動が可能なX線検出器を備えたX線撮影システム100であって、X線検出器の現在の状態から、駆動モードの遷移判断に必要な情報を取得するX線検出器制御部132と、取得された駆動モードの遷移判断に必要な情報に基づいて、X線検出器の駆動モードを通常駆動モードから高速駆動モードに遷移させるか否かの判断を行う駆動モード遷移判断部133を有する。【選択図】図1
