RADIATION IMAGE PHOTOGRAPHING DEVICE, RADIATION IMAGE PHOTOGRAPHING SYSTEM, DETECTING SENSITIVITY CONTROL METHOD FOR IRRADIATION START OF RADIATION AND PROGRAM
PROBLEM TO BE SOLVED: To provide a radiation image photographing device, a radiation image photographing system, a detecting sensitivity control method of the irradiation start of radiation and a program capable of preventing the erroneous detection of the irradiation start of radiation while suppressing power consumption in an irradiation standby state.SOLUTION: Detection means detects the irradiation start of radiation to be applied in the case of photographing a radiation image. Derivation means derives an irradiation dose in a predetermined period of radiation on the basis of input information. Control means controls the detection means to decrease the detecting sensitivity of the irradiation start of radiation such that power supply amounts to the detection means are made smaller according as the irradiation dose of radiation derived by the derivation means is large. Photographing means photographs the radiation image after the irradiation start of irradiation is detected by the detection means.【課題】照射待機状態における電力消費量を抑制しつつ放射線の照射開始の誤検出を防止することができる放射線画像撮影装置、放射線画像撮影システム、放射線の照射開始の検出感度制御方法およびプログラムを提供する。【解決手段】検出手段は、放射線画像を撮影する際に照射される放射線の照射開始を検出する。導出手段は、入力情報に基づいて放射線の所定期間内における照射線量を導出する。制御手段は、導出手段によって導出された放射線の照射線量が大きい程、検出手段に対する電力供給量が小さくなるように検出手段における放射線の照射開始の検出感度を低下させる。撮影手段は、検出手段によって放射線の照射開始が検出された後に放射線画像の撮影を行う。【選択図】図９
