Abstract

There is provided a radiographic imaging system including: a radiographic imaging device including a generating section that captures a radiographic image expressed by irradiated radiation and generates image information expressing the captured radiographic image, and a first communication section that transmits, plural times and by wireless communication and even during a response wait time period, imaging start instructing information that instructs starting of imaging when preparations for capturing a radiographic image by the generating section have been completed; and a control device having a second communication section that can communicate by wireless communication with the first communication section, and a control section that controls a radiation irradiating section such that radiation is irradiated with respect to the radiographic imaging device in a case in which the second communication section receives any of the imaging start instructing information that are transmitted plural times from the first communication section.

Claims

1. A radiographic imaging system comprising:

a radiographic imaging device comprising a generating section that captures a radiographic image expressed by irradiated radiation and generates image information expressing the captured radiographic image, and a first communication section that transmits, plural times and by wireless communication and even during a response wait time period, imaging start instructing information that instructs starting of imaging at a time when preparations for capturing a radiographic image by the generating section have been completed; and

a control device having a second communication section that is able to communicate by wireless communication with the first communication section, and a control section that controls a radiation irradiating section such that radiation is irradiated with respect to the radiographic imaging device in a case in which the second communication section receives any of the imaging start instructing information that are transmitted plural times from the first communication section.

2. The radiographic imaging system of claim 1, wherein the first communication section transmits, at a predetermined cycle, the imaging start instructing information that includes identification information for identifying the number of times of transmissions.

3. The radiographic imaging system of claim 2, wherein the control section changes a time of causing radiation to be irradiated from the radiation irradiating section, on the basis of the identification information that is included in the imaging start instructing information received at the second communication section.

4. The radiographic imaging system of claim 2, wherein

the generating section has plural charge storing sections that accumulate charges generated by radiation being irradiated, and in which charges are respectively accumulated in accordance with an accumulating time period of the charges, and

the first communication section transmits the imaging start instructing information at a time of resetting the charges accumulated in the plural charge storing sections.

5. The radiographic imaging system of claim 4, wherein

the control section effects control such that, in a case in which the imaging start instructing information is received at the second communication section, reply information is transmitted from the second communication section to the first communication section on the basis of the identification information included in the received imaging start instructing information, and

in a case in which the first communication section receives the reply information, the generating section changes a time period for accumulating charges at the charge storing sections at a time of capturing a radiographic image, on the basis of the returned reply information.

6. The radiographic imaging system of claim 1, wherein

the control device further has a receiving section that receives, in two steps, radiographic imaging instructing operations by the generating section, and

in at least one case in which an imaging instructing operation of a first step and an imaging instructing operation of a second step are received at the receiving section, the control section transmits, plural times and by wireless communication and even during a response wait time period and from the second communication section, imaging instructing information that corresponds to the step of the imaging instructing operation.

7. The radiographic imaging system of claim 6, wherein the control device further has a first notification section that gives notice in a case in which the imaging start instructing information is not received even while standing-by during a predetermined imaging standby time period from transmission of the imaging instructing information that corresponds to the imaging instructing operation of the second step.

8. The radiographic imaging system of claim 4, wherein

in a case in which the imaging start instructing information is received at the second communication section, the control section controls the radiation irradiating section, and effects control such that read-out instructing information, that instructs starting of reading-out of accumulated charges, is transmitted from the second communication section to the first communication section after ending of irradiation of radiation from the radiation irradiating section, and

in a case in which the first communication section receives the read-out instructing information transmitted from the second communication section, the generating section starts reading-out of the charges accumulated in the charge storing sections.

9. The radiographic imaging system of claim 8, wherein

the control section transmits the read-out instructing information plural times and by wireless communication and even during a response wait time period, and

in a case in which the first communication section receives any of the read-out instructing information that are transmitted plural times from the second communication section, the generating section starts reading-out of the charges accumulated in the charge storing sections.

10. The radiographic imaging system of claim 8, wherein the control section transmits the read-out instructing information after standing-by for at least a predetermined irradiation standby time period from reception of the imaging start instructing information at the second communication section.

11. The radiographic imaging system of claim 8, wherein in a case in which the read-out instructing information is not received even if standing-by for a predetermined accumulating standby time period from transmission of the imaging start instructing information plural times, the generating section starts reading-out of the charges accumulated in the charge accumulating sections.

12. The radiographic imaging system of claim 1, wherein the radiographic imaging device further has a second notification section that gives notice in a case in which the first communication section receives predetermined instruction information relating to capturing of a radiographic image.

13. The radiographic imaging system of claim 12, wherein the predetermined instruction information is instruction information requesting capturing of a radiographic image.

14. The radiographic imaging system of claim 12, wherein the second notification section gives notice by using at least one of light and sound.

15. The radiographic imaging system of claim 12, wherein the second notification section is provided at a grasping portion for grasping at a time of carrying a main body of the radiographic imaging device.

16. A radiographic imaging device comprising:

a generating section that captures a radiographic image expressed by irradiated radiation, and generates image information expressing the captured radiographic image; and

a communication section that transmits, plural times and by wireless communication and even during a response wait time period, imaging start instructing information that instructs starting of imaging at a time when preparations for capturing a radiographic image by the generating section have been completed.

17. A control device comprising:

a communication section that is able to communicate with a radiographic imaging device that transmits, plural times and by wireless communication and even during a response wait time period, imaging start instructing information that instructs starting of imaging at a time when preparations for capturing a radiographic image have been completed; and

a control section that controls a radiation irradiating section such that radiation is irradiated with respect to the radiographic imaging device in a case in which any of the imaging start instructing information that are transmitted plural times is received from the communication section.
