放射線撮像装置、その制御方法及び放射線撮像システム

摘要

A radiation imaging apparatus (130) including pixels; driving lines; a driving circuit (202); bias lines (BS1 - Bs3, BsC); an acquisition unit (205) configured to acquire an evaluation value based on a current flowing in the bias line; a determination unit (208) configured to compare the evaluation value with a comparison target value to determine whether radiation is irradiated; a control unit (209) configured to control the acquisition unit and the determination unit; and a storage unit (207) configured to store the evaluation value used in the determination process, is provided. A comparison target value used in a given determination process is based on one or more evaluation values used in one or more determination processes which are performed before the given determination process and in which it is determined that radiation has not been irradiated.
