Radiation imaging system

A radiation imaging system comprising:

• a radiation irradiation apparatus that generates radiation;
• a radiation imaging apparatus that generates image data of a radiographic image in accordance with the radiation emitted;
• and
• a synchronization signal transmitter connected to the radiation irradiation apparatus or incorporated in the radiation irradiation apparatus, the synchronization signal transmitter transmitting a synchronization signal to the radiation imaging apparatus, the synchronization signal being used to synchronize operations between the radiation imaging apparatus and the radiation irradiation apparatus, the synchronization signal transmitter storing unique identification information used to identify the synchronization signal transmitter and transmitting the identification information to the radiation irradiation apparatus and the radiation imaging apparatus, respectively, and
• the radiation irradiation apparatus or the radiation imaging apparatus including a hardware processor that determines whether or not the identification information received by the radiation irradiation apparatus and the identification information received by the radiation imaging apparatus are in agreement with each other.
