ABSTRACT:
A control device controls a radiography apparatus including a radiation generating unit that emits radiation, a radiation detecting unit that detects the radiation emitted from the radiation generating unit. The control device includes a positional-relationship detecting unit that detects a positional relationship between the radiation generating unit and the radiation detecting unit when the radiography apparatus performs a radiographic operation; and a control unit that controls the radiographic operation of the radiography apparatus based on the result of the detection performed by the positional-relationship detecting unit.
