  However, the radiation imaging system disclosed in Patent Document 1 described above has a problem that it is difficult for the user to confirm whether or not the wireless communication by the normal wireless communication unit is set to be effective. For example, it is conceivable that the user confirms whether or not wireless communication has been effectively set from the image processing PC that controls the entry device, but it is the user's workflow to move to the image processing PC and confirm each time it is set. This is inefficient.

  On the other hand, Patent Document 2 discloses a radiographic imaging system in which a signal reception state display unit for visually confirming a signal reception state between an imaging unit and a signal transceiver is provided separately from the imaging unit. ing. According to such a radiographic imaging system, it is possible to check the signal reception state between the imaging unit and the signal transceiver. Therefore, it is not necessary to confirm whether or not the wireless communication has been enabled by moving to the image processing PC, and the degree of freedom of the user's workflow flow line is improved.

  However, if an entry device and a signal reception state display unit are provided in the radiation imaging system, the number of devices in the system increases and the cost of the system increases. In addition, when a plurality of radiation imaging apparatuses are to be wirelessly communicated with one radiation imaging system, a signal reception state display unit must be provided for each radiation imaging apparatus, which further increases the cost of the system. There's a problem.

  The present invention has been made in view of the above-described problems, and suppresses an increase in the number of devices in the system and reduces the cost of the system when configuring a radiation imaging system capable of confirming the states of a plurality of radiation imaging devices. The purpose is to let you.

  The present invention is a state display device for displaying the state of a radiation imaging apparatus in a radiation imaging system, and communication information for communicating with the radiation imaging apparatus via a communication means is transmitted via a wireless communication means. The state of one of the plurality of radiation imaging apparatuses including the transmission means for transmitting to the radiation imaging apparatus and the radiation imaging apparatus in which the communication information transmitted by the transmission means is set via the communication means. Receiving and displaying status display means.

  ADVANTAGE OF THE INVENTION According to this invention, when comprising the radiography system which can confirm the state of several radiography apparatus, the increase in the number of apparatuses of a system can be suppressed and the cost of a system can be reduced.

In order to add the portable imaging device 110 to the radiation imaging system 100, the user makes the portable imaging device 110 face the state display device 140. Next, the user presses either a communication start switch that is a part of the operation unit 115 of the portable imaging device 110 or a communication start switch that is a part of the operation unit 144 of the status display device 140. Communication between the portable imaging device 110 and the status display device 140 starts in response to pressing of the communication start switch.

Hereinafter, processing of the radiation imaging system 100 will be described with reference to the flowchart of FIG.
In step S <b> 301, the CPU 116 of the portable imaging device 110 transmits a communication information request signal to the status display device 140 via the infrared communication interface 113 in order to enable wireless communication with the wireless LAN base station 160. At this time, the CPU 116 of the portable imaging device 110 also transmits its own device information to the status display device 140.
In step S311, the CPU 145 of the status display device 140 receives a request signal and device information via the infrared communication interface 143. The infrared communication interface 143 corresponds to an example of a second receiving unit. Here, the communication information is information of wireless communication parameters necessary for starting wireless LAN communication, for example, information including the SSID described above. Next, the CPU 145 of the status display device 140 transmits communication information to the portable imaging device 110 to instruct the setting of communication between the portable imaging device 110 and the wireless LAN base station 160. The CPU 145 corresponds to an example of an instruction unit.

In step S <b> 302, the CPU 116 of the portable imaging device 110 sets the received communication information after receiving the communication information. This process enables communication between the portable imaging device 110 and the wireless LAN base station 160.
In step S <b> 303, the CPU 116 of the portable imaging device 110 transmits a communication information setting completion notification to the status display device 140.

To the user. This processing corresponds to an example of processing by the completion display means. Specifically, CPU145 notifies by lighting the LED indicator which is the display part 141 with a specific pattern. If the portable imaging device 110 cannot set communication information, the CPU 145 of the status display device 140 notifies the user that the portable imaging device 110 could not be added to the radiation imaging system 100.
In step S <b> 313, the CPU 145 of the status display device 140 transmits a notification that the portable imaging device 110 has been added to the radiation imaging system 100 to the image display device 150. At this time, the CPU 145 also transmits device information of the added portable photographing device 110 to the image display device 150.

In step S <b> 321, the CPU 151 of the image display device 150 receives the notification that it has been added, adds the portable imaging device 110 to the list of usable radiation imaging devices, and displays it on the display unit 156. On the display unit 156, the stationary imaging device 120 and the portable imaging device 110 are displayed in a list.
Therefore, the user can confirm whether or not the process of adding the portable imaging device 110 to the radiation imaging system 100 is successful by viewing either the status display device 140 or the image display device 150.

As described above, communication between the radiographic imaging apparatus 110 and the wireless LAN base station 160 is enabled by matching the SSIDs of the radiation imaging system 100 and the portable imaging apparatus 110. Therefore, the portable imaging device 110 and the radiation generator 130 can be synchronized via the wireless LAN. In addition, the portable imaging device 110 and the image display device 150 can communicate with each other via a wireless LAN. Therefore, the image display device 150 can display the radiation image data captured by the portable imaging device 110 and the stationary imaging device 120 on the display unit 156. Further, the image display device 150 can receive the states of both the portable imaging device 110 and the stationary imaging device 120.
At this time, the image display device 150 determines that the portable imaging device 110 has been selected for the next imaging on the basis that the portable imaging device 110 was recently added to the radiation imaging system 100. The image display device 150 transmits the status of the portable imaging device 110 received from the selected portable imaging device 110 to the status display device 140, so that the status display device 140 displays the status of the portable imaging device 110. Specifically, the CPU 151 of the image display device 150 receives the status of the portable imaging device 110 from the portable imaging device 110 via the wireless LAN base station 160, and the status display device displays the received status of the portable imaging device 110. 140. The status display device 140 receives the status of the portable imaging device 110 via the USB cable 104 connected to the connector. The connector corresponds to an example of second receiving means.

  The image display device 150 is configured such that the user can select one radiation imaging device from the list of a plurality of radiation imaging devices displayed on the display unit 156 by the operation unit 155. The state display device 140 displays the state of the selected radiation imaging apparatus by the image display device 150 transmitting the state of the radiation imaging apparatus selected by the user to the state display device 140. Therefore, the user can display the state of an arbitrary radiation imaging apparatus on the state display device 140 by selecting the radiation imaging apparatus.

According to the present embodiment, since the state display device 140 also serves as a communication terminal on the system side when adding a radiation imaging apparatus to the system, an increase in the number of apparatuses of the radiation imaging system 100 can be suppressed and costs can be reduced. Can do.
In addition, the status display device 140 displays the status of one selected radiographic apparatus from among a plurality of radiographic apparatuses constituting the radiographic system 100. Therefore, it is not necessary to provide a state display device for each of the plurality of radiation imaging apparatuses, and an increase in the number of apparatuses of the radiation imaging system 100 can be suppressed and the cost can be reduced.
Further, since the status display device 140 displays whether or not the process of adding the radiation imaging apparatus to the radiation imaging system 100 is successful, the degree of freedom of the flow line of the user's workflow can be improved.

(Second Embodiment)
In the second embodiment, the processing of the state display device 140 when adding the portable imaging device 110 to the radiation imaging system 100 is different from that in the first embodiment. The display unit 141 of the status display device 140 can display a character string and the like. Note that the configuration in the radiation imaging system of this embodiment is the same as that of the first embodiment, and a description thereof will be omitted.

Hereinafter, processing of the radiation imaging system 100 will be described with reference to the flowchart of FIG. 4 and FIG. 5. FIG. 5 is a diagram illustrating an example of communication contents. Here, a case will be described in which the portable imaging device 110 used in the imaging room C (roomC) is used in the imaging room A (roomA).
In step S 401, the CPU 116 of the portable imaging device 110 transmits a communication information request signal to the status display device 140 via the infrared communication interface 113 in order to enable wireless communication with the wireless LAN base station 160. At this time, the CPU 116 of the portable imaging device 110 also transmits its own device information to the status display device 140. Specifically, as shown in FIG. 5, the CPU 116 of the portable imaging device 110 transmits its product type and serial number to the status display device 140.

  In step S411, the CPU 145 of the status display device 140 receives a request signal and device information via the infrared communication interface 143. The CPU 145 of the status display device 140 determines whether or not the portable imaging device 110 is registered in the radiation imaging system 100 based on the received device information. For example, the status display device 140 determines whether or not the portable imaging device 110 exists in a registered radiation imaging device stored in advance. For example, the status display device 140 transmits device information to the image display device 150 and inquires of the image display device 150 whether the portable imaging device 110 has been registered. The image display device 150 determines whether the portable imaging device 110 exists in the registered radiation imaging device stored in advance in the HDD 154, and transmits the inquiry result to the status display device 140. If portable imaging device 110 is registered, the process proceeds to step S413, and if not registered, the process proceeds to step S412.

  In step S412, the CPU 145 of the status display device 140 newly generates an identification name of the portable imaging device 110 and registers the portable imaging device 110. The identification name generated by the CPU 145 only needs to be unique only within the system, and the identification name with the same name may be used in another system at the same time. It may be another identification name. Note that the processing of step S412 may be performed by the CPU 151 of the image display device 150.

  In step S413, the CPU 145 of the status display device 140 transmits the communication information, the system identification name, and the registered radiation imaging device identification name to the portable imaging device 110 via the infrared communication interface 143. Here, the communication information is information necessary to start wireless LAN communication, and can include a wireless encryption passphrase, a physical channel, and the like in addition to the SSID described above. 5, the SSID is “roomA”, the system identification name is “imaging room A”, and the radiation imaging apparatus identification name is “half-cut cassette No. 2”. Here, a character string is transmitted as the identification name, but binary data may be transmitted.

In step S402, after receiving the communication information, the CPU 116 of the portable imaging device 110 sets the received communication information. This process enables communication between the portable imaging device 110 and the wireless LAN base station 160.
In step S <b> 403, the CPU 116 of the portable imaging device 110 transmits a communication information setting completion notification to the status display device 140. In FIG. 5, the CPU 116 notifies “roomC” as the SSID used until immediately before, in order to indicate that the SSID has been switched by the setting.

In step S414, after receiving the notification of setting completion, the CPU 145 of the status display device 140 has added the portable imaging device 110 to the radiation imaging system 100, that is, the portable imaging device 110 has completed setting communication information. To the user. If the portable imaging device 110 cannot set communication information, the CPU 145 of the status display device 140 notifies the user that the portable imaging device 110 could not be added to the radiation imaging system 100. Therefore, the user can confirm whether or not the addition of the portable imaging device 110 has succeeded only by confirming the status display device 140 at hand without moving to the image display device 150.
In step S415, the CPU 145 of the status display device 140 transmits a notification to the effect that the portable imaging device 110 has been added to the radiation imaging system 100 to the image display device 150.
In step S <b> 421, the CPU 151 of the image display device 150 receives the notification that it has been added, and then adds the portable imaging device 110 to the list of usable radiation imaging devices and displays it on the display unit 156.

FIG. 6 is a diagram illustrating an example of display contents of the portable imaging device 110 and the status display device 140 of the present embodiment.
First, the portable imaging apparatus 110 is used in a system in another place until immediately before, and the display unit 111 has a system identification name “imaging room C” and a radiation imaging apparatus assigned in the system. The identification name “half-cut cassette No. 1” is displayed. When the portable imaging apparatus 110 is used in the system of the “imaging room A”, the SSID set in the radiation imaging apparatus in this state is also the SSID of the previous system, so the image display apparatus 150 of the “imaging room A”. Cannot be used for shooting.

  Here, it is assumed that the portable photographing apparatus 110 is brought into “photographing room A” from “photographing room C” and used. Although the user brings the radiation imaging apparatus to the place of use, as shown in FIG. 6A, at this time, “imaging room C” is displayed on the display unit 111 of the portable imaging apparatus 110. For this reason, the user can recognize that communication settings are necessary for use in the “photographing room A”.

  Next, the portable imaging device 110 and the status display device 140 are opposed to each other, and when the user presses the communication start switch, as shown in FIG. Communication is started and information such as communication information is transmitted and received. When the portable imaging device 110 transmits a notification of the completion of communication information setting, as shown in FIG. 6C, the status display device 140 displays that the portable imaging device 110 has been added to the system, and The identification name of the portable imaging device 110 and the identification name of the system are displayed. 6C, the portable imaging apparatus 110 simultaneously displays the newly assigned system identification name “imaging room A” and the radiation imaging apparatus identification name “half-cut cassette No. 2”. Switch.

  Thereafter, the state of the portable photographing device 110 is transmitted to the image display device 150 via the wireless LAN without the portable photographing device 110 and the state display device 140 being opposed to each other. Therefore, when the status display device 140 receives and displays the status of the portable imaging device 110 via the image display device 150, the user can check the status of the portable imaging device 110.

According to this embodiment, since the identification name of the system and the identification name of the radiation imaging apparatus are displayed on both the radiation imaging apparatus and the status display apparatus 140, the user can identify the status display apparatus 140 and the radiation imaging apparatus. The correspondence can be easily recognized.
In addition, since the identification name of the system is displayed on the radiation imaging apparatus, whether or not the user is performing an operation of adding the radiation imaging apparatus to the system when the radiation imaging apparatus is brought from another system and used in the own system. Can be easily identified.

(Third embodiment)
In 3rd Embodiment, the structure of the radiography system 200 differs from the radiography system 100 of 1st and 2nd embodiment. In addition, the same structure of 1st Embodiment attaches | subjects the same code | symbol, and abbreviate | omits the description.
FIG. 7 is a schematic diagram illustrating an example of the radiation imaging system 200 according to the present embodiment.

The status display device 170 of this embodiment has a wireless LAN interface 171. That is, the status display device 170 is not directly connected to the image display device 150 but communicates with other devices via communication between the wireless LAN interface 171 and the wireless LAN base station 160. The status display device 170 needs communication information such as SSID in order to perform wireless communication with other devices, but it is assumed that the communication information is set in advance when the system is installed. That is, the status display device 170 of the present embodiment has portability by operating wirelessly, but cannot move between systems.

  In this embodiment, the management method of the identification name of the radiation imaging apparatus is different from that of the second embodiment. In the second embodiment, the identification name of the radiation imaging apparatus is automatically generated in each system so as to be unique only within a single system. In this embodiment, the identification name of the radiation imaging apparatus is a property of the radiation imaging apparatus, and is fixedly set in advance to the radiation imaging apparatus at the time of installation so as to be unique across a plurality of systems that may move. . Therefore, in the present embodiment, the communication content between the portable imaging device 110 and the status display device 170 is different from that in the second embodiment.

Send. At this time, the CPU 116 of the portable imaging device 110 b also transmits its own device information to the status display device 170. Specifically, as shown in FIG. 9, the CPU 116 of the portable imaging device 110 b transmits its product type, serial number, and identification name to the status display device 170. Here, “half-cut cassette No. 2” is set in advance as a unique identification name in the portable photographing apparatus 110b.

In step S811, the CPU 145 of the status display device 170 receives a request signal and device information via the infrared communication interface 143. The CPU 145 of the status display device 170 determines whether or not the portable imaging device 110b is registered in the radiation imaging system 200 based on the received device information. The processing in step S811 may be performed by the CPU 151 of the image display device 150, as in the second embodiment. If portable imaging device 110b is registered, the process proceeds to step S813, and if not registered, the process proceeds to step S812.
In step S812, the CPU 145 of the status display device 170 stores the identification name of the portable imaging device 110b and registers the portable imaging device 110b. Note that the processing in step S812 may be performed by the CPU 151 of the image display device 150.

In step S813, the CPU 145 of the status display device 170 transmits communication information and a system identification name to the portable imaging device 110b via the infrared communication interface 143. In FIG. 9, the SSID is transmitted as “roomA”, the system identification name is “imaging room A”, and the identification name of the radiation imaging apparatus is not transmitted.
The subsequent processing is the same as that in the flowchart of FIG.
Accordingly, the image display device 150 transmits the status of the portable imaging device 110 received from the portable imaging device 110b to the status display device 170, so that the status display device 170 displays the status of the portable imaging device 110b. Specifically, the CPU 151 of the image display device 150 receives the state of the portable imaging device 110b from the portable imaging device 110b via the wireless LAN base station 160. The CPU 151 of the image display device 150 transmits the received state of the portable imaging device 110 to the state display device 170 via the wireless LAN base station 160.
