Radiation imaging apparatus, radiation imaging system, radiation imaging method, and storage medium

1 . A radiation imaging apparatus that performs radiation imaging by detecting radiation emitted from a radiation source,

wherein, in a case where the radiation imaging apparatus is in a standby state in which the radiation imaging apparatus awaits an activation signal transmitted from a control apparatus that is placed outside the radiation imaging apparatus and that controls the radiation imaging apparatus, the radiation imaging apparatus transmits internal information about the radiation imaging apparatus to the control apparatus,

wherein, upon receiving the internal information about the radiation imaging apparatus, the control apparatus causes a display device to display the internal information about the radiation imaging apparatus, and

wherein a wireless communication method used to transmit the internal information about the radiation imaging apparatus to the control apparatus is a shorter-range wireless communication method than a wireless communication method used to transmit image data captured by the radiation imaging of the radiation imaging apparatus.

2 . The radiation imaging apparatus according to claim 1 , wherein the internal information includes at least one of individual identification information, a number of images not transferred yet, a number of images savable, a remaining battery level, communication environment information, error information, an internal temperature, angular information, and positional information.

3 . The radiation imaging apparatus according to claim 1 , wherein the internal information includes a remaining battery level.

4 . The radiation imaging apparatus according to claim 1 , wherein the radiation imaging apparatus transmits the internal information to the control apparatus at predetermined time intervals.

5 . The radiation imaging apparatus according to claim 1 , wherein the radiation imaging apparatus transmits the internal information to the control apparatus in a case where the radiation imaging apparatus is in a predetermined state.

6 . The radiation imaging apparatus according to claim 5 , wherein the predetermined state is a state in which acceleration equal to or greater than a predetermined value is applied to the radiation imaging apparatus.

7 . The radiation imaging apparatus according to claim 5 , wherein the predetermined state is a state in which an internal temperature of the radiation imaging apparatus is equal to or greater than a predetermined value.

8 . The radiation imaging apparatus according to claim 1 , comprising:

a first control unit that controls the radiation imaging apparatus in the radiation imaging; and

a second control unit that is different from the first control unit,

wherein the standby state is a state in which the first control unit is not activated.

9 . The radiation imaging apparatus according to claim 8 , wherein, in the standby state, the second control unit activates the first control unit in response to reception of the activation signal by the radiation imaging apparatus.

10 . The radiation imaging apparatus according to claim 9 , wherein the second control unit determines, based on the internal information, whether to activate the first control unit in response to the reception of the activation signal.

11 . The radiation imaging apparatus according to claim 1 ,

wherein the activation signal includes imaging protocol information, and

wherein the radiation imaging apparatus determines a sequence for transitioning the radiation imaging apparatus to a state in which the radiation imaging is possible based on the imaging protocol information.

12 . The radiation imaging apparatus according to claim 11 , wherein the imaging protocol information indicates at least one of an imaging mode, an imaging technique, a tube voltage and a tube current of radiation emitted from a radiation source, and an irradiation time.

13 . A radiation imaging system, comprising:

the radiation imaging apparatus according to claim 1 ; and

the control apparatus.

14 . A radiation imaging method, comprising:

transmitting, in a case where a radiation imaging apparatus that performs radiation imaging by detecting radiation emitted from a radiation source is in a standby state in which the radiation imaging apparatus awaits an activation signal transmitted from a control apparatus that is placed outside the radiation imaging apparatus and that controls the radiation imaging apparatus, internal information about the radiation imaging apparatus to the control apparatus; and

displaying, by the control apparatus, the internal information about the radiation imaging apparatus on a display device in a case where the internal information about the radiation imaging apparatus is received,

wherein a wireless communication method used to transmit the internal information about the radiation imaging apparatus to the control apparatus is a shorter-range wireless communication method than a wireless communication method used to transmit image data captured by the radiation imaging of the radiation imaging apparatus.

15 . A non transitory computer-readable storage medium storing a program for causing a computer to execute the method according to claim 14 .
