Transmission apparatus, radiation imaging system, and transmission control apparatus

1. A transmission apparatus, comprising:

a transmission unit that transmits an operation state of a radiation imaging system to a user; and

a control unit that controls a state of the transmission unit, wherein

when imaging an exposure image by an exposure including a first exposure and a second exposure in the radiation imaging system, the control unit controls the state of the transmission unit such that the state of the transmission unit between the first exposure and the second exposure, the state of the transmission unit at a time of the imaging of the first exposure and the state of the transmission unit at a time of the imaging of the second exposure are a same state,

the first exposure and the second exposure are series of imaging, and

the first exposure is performed prior to the second exposure.

2. The transmission apparatus according to claim 1 , wherein

two or more of the transmission units are installed, and

the control unit controls at least one of the two or more of the transmission units such that a state of the at least one of the two or more of the transmission units between the first exposure and the second exposure, the state of the at least one of the two or more of the transmission units at a time of the imaging of the first exposure and the state of the at least one of the two or more of the transmission units at a time of the imaging of the second exposure are a same state.

3. The transmission apparatus according to claim 2 , wherein

the control unit sets a second transmission unit other than a first transmission unit to be in a state different from that of the first transmission unit between the first exposure and the second exposure, the first transmission unit having been set to be in the state based on that at the time of the imaging of the exposure image.

4. The transmission apparatus according to claim 2 , wherein

the control unit is capable of selecting a plurality of transmission patterns including a combination of states between the first exposure and the second exposure in the two or more of the transmission units and sets one transmission pattern selected from among the plurality of transmission patterns to be a state of the two or more of the transmission units.

5. The transmission apparatus according to claim 4 , wherein

the control unit selects the one transmission pattern based on at least one of information on the user and information on an apparatus related to the radiation imaging system.

6. The transmission apparatus according to claim 1 , wherein

the transmission unit comprises a device that acts on at least one of a visual sense, a hearing sense or a tactile sense of the user.

7. The transmission apparatus according to claim 1 , wherein

the control unit decides an imaging condition for performing the second exposure, based on a preliminary exposure image obtained by the first exposure performed prior to the second exposure and on information related to the preliminary exposure image.

8. The transmission apparatus according to claim 7 , wherein

the imaging condition is an imaging condition for combining the preliminary exposure image obtained by the first exposure and a main exposure image obtained by the second exposure.

9. A radiation imaging system, comprising:

a radiation irradiation apparatus that emits radiation for exposure;

a radiation imaging apparatus that generates image data of an exposure image by receiving an exposure of the radiation; and

the transmission apparatus according to claim 1 .

10. The radiation imaging system according to claim 9 , wherein

the transmission unit and the control unit are installed in the radiation irradiation apparatus.

11. The radiation imaging system according to claim 10 , wherein

an imaging condition for performing the second exposure, which are determined based on information on a preliminary exposure image, is an imaging condition related to a dose or an irradiation time.

12. The radiation imaging system according to claim 9 , wherein

the transmission unit is installed in the radiation irradiation apparatus, and

the control unit is installed in the radiation imaging apparatus.

13. The radiation imaging system according to claim 9 , wherein

the transmission unit is a lamp that is included in a hand switch used by the user to operate the radiation imaging system.

14. The transmission apparatus according to claim 1 , wherein

the first exposure is performed at a dose lower than a dose of the second exposure.

15. The transmission apparatus according to claim 1 , wherein

the exposure image is imaged without operating an exposure switch between the first exposure and the second exposure.

16. The transmission apparatus according to claim 1 , wherein

a plurality of the second exposure are performed after the first exposure.

17. A transmission control apparatus that controls a transmission unit that transmits an operation state of a radiation imaging system to a user, the transmission control apparatus comprising

a control unit that decides a state of the transmission unit and controls the transmission unit such that the transmission unit is in the decided state of the transmission unit, wherein

when imaging an exposure image by an exposure including a first exposure and a second exposure in the radiation imaging system, the control unit controls the state of the transmission unit such that the state of the transmission unit between the first exposure and the second exposure, the state of the transmission unit at a time of the imaging of the first exposure and the state of the transmission unit at a time of the imaging of the second exposure are a same state,

the first exposure and the second exposure are series of imaging, and

the first exposure is performed prior to the second exposure.
