Imaging control apparatus, radiation imaging system, imaging control method, and storage medium

A radiation imaging system comprising an imaging control apparatus configured to control a radiation generating apparatus and a radiation imaging apparatus,

• wherein the imaging control apparatus comprises
• an irradiation field obtaining unit configured to obtain irradiation field information in the radiation imaging by an irradiation field obtaining method based on at least one of a radiation image obtained by radiation imaging, imaging information concerning the radiation imaging, and preset irradiation field information concerning the radiation imaging, and
• an area dose obtaining unit configured to obtain an area dose in the radiation imaging based on the irradiation field information, and
• wherein in a case the irradiation field information is not obtained, the irradiation field obtaining unit obtains the irradiation field information based on an irradiation field obtaining method different from the irradiation field obtaining method.

An imaging control method for an imaging control apparatus, the method comprising:

• obtaining irradiation field information in radiation imaging by an irradiation field obtaining method based on any one of a radiation image obtained by the radiation imaging, imaging information concerning the radiation imaging, and preset irradiation field information in the radiation imaging;
• and
• obtaining an area dose in the radiation imaging based on the irradiation field information,
• wherein in the obtaining the irradiation field, in a case the irradiation field information is not obtained, the irradiation field information is obtained based on an irradiation field obtaining method different from the irradiation field obtaining method.
