PROBLEM TO BE SOLVED: To provide a radiation imaging apparatus capable of stabilizing the dark current, lag, and sensitivity of an imaging apparatus, reducing the power consumption and amount of heat generation of a light source, and suppressing the acceleration of the deterioration of a conversion element. SOLUTION: The radiation imaging apparatus includes: flat panel detectors 102, 104 including a conversion unit, where the conversion unit includes a plurality of pixels, arranged into a matrix form and each of the pixels includes a conversion element capable of converting a radiation ray into electric charge; a light source 105 capable of emitting light to the conversion unit; and a control unit 107, configured to control the flat panel detectors and the light source. The control unit controls the emission of light from the light source, based on the signal output from the flat panel detectors. COPYRIGHT: (C)2009,JPO&INPIT |
