Abstract:
A radiation image obtaining apparatus for obtaining a radiation image of an object, comprising:a radiation image sensing unit having a plurality of photoelectric converting elements two-dimensionally arranged in a matrix manner; a sensor for detecting irradiation of radiation; and an image sensing controller connected to said radiation image sensing unit, said sensor and a radiation controller, for controlling a state of said radiation image sensing unit, wherein said image sensing controller comprises: a synchronizing unit for transmitting a signal to the radiation controller to start the irradiation of radiation in accordance with a start of an image sensing state of said radiation image sensing unit in which image sensing is enabled; a determining unit connected to said sensor for determining an irradiation state of radiation on the basis of an output from said sensor; and a drive controller for switching the state of said radiation image sensing unit from the image sensing state to an output state in which an output of image data is enabled on the basis of the determination by said determining unit.
