Radiation imaging apparatus and radiation imaging system

A radiation imaging system comprising a radiation imaging apparatus having a radiation detector configured to be subjected to an incident radiation to obtain a radiation image, and a radiation generation apparatus configured to perform radiation irradiation, the radiation imaging system comprising one or more controllers configured to:

• acquire radiation dose information of the radiation incident on the radiation detector;
• acquire imaging condition information for radiation imaging for subjecting the radiation detector to the incident radiation for up to a target radiation dose to acquire the radiation image;
• and
• stop, in a case where, after a start of the radiation imaging based on the imaging condition information, radiation dose information acquired by a predetermined timing does not satisfy a predetermined condition, the radiation irradiation by the radiation generation apparatus before the incident radiation dose reaches the target radiation dose,
• wherein radiation irradiation time set in the radiation generation apparatus includes a backup time, and
• wherein the predetermined timing is a timing corresponding to a predetermined proportion of the backup time.
