Radiation imaging system, imaging control apparatus, radiation imaging apparatus, radiation imaging method, and non-transitory computer readable storage medium

A radiation imaging system comprising a radiation imaging apparatus and an imaging control apparatus, the radiation imaging apparatus integrating a dose detected by a dose detection pixel that detects a dose of radiation irradiated from a radiation source, and the imaging control apparatus controlling the radiation imaging apparatus, wherein the imaging control apparatus

• transmits information regarding a third region, which is obtained by excluding a second region including a non-integrated dose detection pixel where integration is not performed from a first region including the dose detection pixel in an imaging region of the radiation imaging apparatus, to the radiation imaging apparatus, and
• the radiation imaging apparatus
• outputs a signal regarding stopping the irradiation of the radiation by using a dose detected by the dose detection pixel included in the third region.

An imaging control apparatus comprising a radiation imaging apparatus, the radiation imaging apparatus integrating a dose detected by a dose detection pixel that detects a dose of radiation irradiated from a radiation source, and the imaging control apparatus controlling the radiation imaging apparatus,

• wherein the imaging control apparatus
• transmits information regarding a third region, which is obtained by excluding a second region including a non-integrated dose detection pixel where integration is not performed from a first region including the dose detection pixel in an imaging region of the radiation imaging apparatus, to the radiation imaging apparatus.

A controlling method of a radiation imaging system comprising a radiation imaging apparatus and an imaging control apparatus, the radiation imaging apparatus integrating a dose detected by a dose detection pixel that detects a dose of radiation irradiated from a radiation source, and the imaging control apparatus controlling the radiation imaging apparatus, the controlling method comprising:

• controlling the radiation imaging apparatus to transmit information regarding a third region, which is obtained by excluding a second region including a non-integrated dose detection pixel where integration is not performed from a first region including the dose detection pixel in an imaging region of the radiation imaging apparatus, to the radiation imaging apparatus, and
• controlling the radiation imaging apparatus to output a signal regarding stopping the irradiation of the radiation by using a dose detected by the dose detection pixel included in the third region.
