1. A radiation imaging apparatus comprising:
a radiation detection unit;
a communication unit configured to receive a setting including an imaging mode at a time of acquiring a radiographic image by the radiation detection unit from a control apparatus;
a storage unit configured to store correction data for correcting the radiographic image; and
a control unit configured to control an operation of at least one of the radiation detection unit, the communication unit, and the storage unit,
wherein, in a case where imaging is started in a normal imaging state in which communication between the communication unit and the control apparatus is in a normal state, the control unit acquires first correction data by a first preparation operation of driving the radiation detection unit in a non-irradiation state in the imaging mode received by the communication unit, and in a case where imaging is started in an emergency imaging state in which the communication state is not in the normal state, the control unit acquires second correction data that is usable in an abnormal imaging mode set in advance from the storage unit.
