a storage unit configured to, in a case where radiographic imaging is performed when in a first imaging state, in which a state of communication with the control apparatus is abnormal, store radiographic imaging information from the radiographic imaging; and a communication control unit configured to, upon a transition from the first imaging state to a second imaging state, in which the state of communication with the control apparatus is normal, transmit the radiographic imaging information stored in the storage unit to the control apparatus. ## Claims ### Claim 1 A radiographic imaging apparatus configured to communicate with a control apparatus, the radiographic imaging apparatus comprising: a processor; and a memory storing a program which, when executed by the processor causes the radiographic imaging apparatus to: detect incident radiation rays to acquire a radiographic image; determine whether the radiographic imaging apparatus is in a first imaging state, in which a state of communication with the control apparatus is not normal, or in a second imaging state, in which the state of communication is normal; store radiographic imaging information in the first imaging state when it is determined that the radiographic imaging apparatus is in the first imaging state; and transmit the radiographic imaging information to the control apparatus upon a transition from the first imaging state to the second imaging state. ### Claim 2 (depends on 1) The radiographic imaging apparatus according to claim 1, wherein the radiographic imaging information includes at least one of examination information, image acquisition information, and irradiation execution information, the examination information includes at least one of subject information in the radiographic imaging and imaging protocol information, the image acquisition information includes at least one of a captured image that is the radiographic image acquired through the radiographic imaging, date-and-time information of the radiographic imaging, image acquisition conditions in acquiring the radiographic image, and cumulative pixel value information in a region of interest, and the irradiation execution information includes at least one of irradiation condition information of the radiation rays and cumulative irradiation dose information of the radiation rays. ### Claim 3 (depends on 2) The radiographic imaging apparatus according to claim 2, wherein the image acquisition information includes, as the captured image, the radiographic image of all frames acquired when in the first imaging state. ### Claim 4 (depends on 2) The radiographic imaging apparatus according to claim 2, wherein the image acquisition information includes, as the captured image, a selected image selected from among the radiographic image of a plurality of frames acquired when in the first imaging state. ### Claim 5 (depends on 4) The radiographic imaging apparatus according to claim 4, wherein the selected image is the radiographic image acquired last among the radiographic image of the plurality of frames. ### Claim 6 (depends on 2) The radiographic imaging apparatus according to claim 2, wherein the image acquisition information includes, as the captured image, an image obtained by size-reducing or compressing the radiographic image acquired when in the first imaging state. ### Claim 7 (depends on 2) The radiographic imaging apparatus according to claim 2, wherein the processor further causes the radiographic imaging apparatus to: input the examination information, wherein the radiographic imaging information includes the examination information inputted. ### Claim 8 (depends on 2) The radiographic imaging apparatus according to claim 2, wherein the processor further causes the radiographic imaging apparatus to: acquire the irradiation execution information in irradiation with the radiation rays executed at a radiation generating apparatus configured to generate the radiation rays, wherein the radiographic imaging information includes the irradiation execution information. ### Claim 9 (depends on 1) The radiographic imaging apparatus according to claim 1, wherein when in the second imaging state, image acquisition conditions for acquiring the radiographic image are received from the control apparatus. ### Claim 10 A method of controlling a radiographic imaging apparatus configured to be able to communicate with a control apparatus and including a radiation detecting unit configured to detect incident radiation rays to acquire a radiographic image, the method comprising: determining whether the radiographic imaging apparatus is in a first imaging state, in which a state of communication with the control apparatus is not normal, or in a second imaging state, in which the state of communication is normal; and storing, in a case where it is determined that the radiographic imaging apparatus is in the first imaging state, radiographic imaging information in the first imaging state into a storage unit; and transmitting, upon a transition from the first imaging state to the second imaging state the radiographic imaging information stored in the storage unit to the control apparatus.
