Description

  The present invention relates to a radiation imaging apparatus and a radiation imaging system provided with the apparatus.

The radiation imaging apparatus transitions to a state capable of generating a radiation image (detects radiation) by receiving a signal instructing start of imaging from the control device, and after generating the radiation image, the image data thereof Are generally configured to be sent to the controller. Therefore, when communication can not be performed between the control device and the radiation imaging apparatus, there is a problem that imaging can not be performed.
Such problems rarely occur when the control device and the radiation imaging apparatus are connected by wire or wirelessly connected in a good communication environment such as a general imaging room. However, when wireless connection is performed in a poor communication environment such as an operating room, it is often difficult to stably continue imaging.

Therefore, conventionally, a radiation imaging system as described in Patent Document 1 has been proposed. The radiation imaging system is configured to use two types of imaging modes, slave mode and stand-alone mode, according to the communication state between the control device and the radiation imaging apparatus.
The slave mode is an imaging mode used when the control device and the radiation imaging apparatus can communicate with each other while being set as an initial state, and the radiation imaging apparatus stores and reads electric charges based on an imaging start request from the control apparatus. And send the image to the control device.
The stand-alone mode is an imaging mode used when communication is not possible, and the radiation imaging apparatus autonomously detects radiation, stores and reads electric charges, and stores image data in an internal memory.
By doing this, it is possible to continue imaging even when communication between the control device and the radiation imaging apparatus is interrupted.

In addition, the imaging device 2 may be provided with notification means for notifying that the radiation has been detected by light, voice, vibration or the like.
At that time, notification of different modes may be performed depending on whether radiation is detected in the unreserved state and radiation is detected in the reserved state.
Further, the imaging apparatus 2 may be provided with a function of notifying the console 3 that the radiation has been detected, and the console 3 may display the effect.
At that time, the console 3 may be notified of an indicator such as the intensity of the detected radiation.
Alternatively, the detected image may be analyzed (histogram, shape), and when the result is largely different from that of the other images, the console 3 may be notified when transmitting the image data. If the analysis results are largely different, such images may be excluded because they may be unexposed images or scattered radiation / secondary radiation images.

[Operation of radiation imaging system]
Next, the operation of the radiation imaging system 100 will be described.
FIGS. 4 and 5 are ladder charts showing the flow of examination using the radiation imaging system 100 according to the present embodiment, and FIGS. 6 to 9 are ladders showing the flow of examination using the radiation imaging system according to the modification of the present embodiment. It is a chart.

(Operation example)
The basic flow of inspection using the radiation imaging system 100 of the present embodiment is as shown in FIG.
First, the prepared photographing device 2 is in the photographing standby state (step A1).
Thereafter, when the user makes a reservation for photographing via the operation unit 35 of the console 3 (step A2), the console 3 transmits photographing order information to the photographing device 2 (step A3).

In this state, when the radiation irradiating apparatus 1 irradiates radiation toward the subject and the imaging apparatus 2 behind it (step A4), the imaging apparatus 2 detects the radiation and immediately accumulates (photographs) electric charge (step A5). Then, image data is generated (step A6), and the generated image data is stored in the storage unit 33 (step A7). At this time, photographing order information, incidental information, and the like are linked to the generated image data. Then, the photographing device 2 transmits the image data to the console 3 (step A8).
After step A8, the photographing device 2 transitions to the photographing standby state again (step A1).

When the console 3 receives the image data, it stores it in the storage unit 33 (step A9). Then, the console 3 displays a radiation image based on the received image data on the display unit 34 (step A10), and transmits a data reception completion notification notifying that the image data has been received to the imaging device 2 (step A11) .
When the photographing device 2 receives the data reception completion notification, the photographing device 2 deletes the image data stored in the storage unit 33 (step A12).

Here, when communication between the imaging device 2 and the console 3 is interrupted due to the influence of an external electromagnetic wave or the like, even if the user makes a reservation for imaging (step A2), the console 3 captures the imaging order information It can not be sent to step 2 (step A3f). However, since the imaging device 2 of this embodiment detects radiation irradiation and performs imaging autonomously, if radiation is emitted from the radiation irradiation device 1 (step A4), there is no abnormality in the communication state and Similarly, photographing and generation of image data (steps A5 and A6) can be performed.
However, at this stage, since the photographing order information has not arrived at the photographing device 2, the photographing order information and the like can not be linked to the image data in step A7. Also, the photographing device 2 can not transmit image data (step A8 f).
Therefore, the console 3 can not perform steps A9 to A11, and accordingly, the photographing device 2 can not perform step A12.

Thereafter, when the communication between the photographing device 2 and the console 3 is recovered, the console 3 detects it (step A13), and photographs a confirmation signal for confirming the presence or absence of unsent image data (remaining in the storage unit 25). It transmits to the apparatus 2 (step A14).
When the photographing device 2 receives the confirmation signal, the photographing device 2 transmits unsent image information (such as an ID) regarding unsent image data to the console 3 (step A15).
When the console 3 receives the unsent image information, the console 3 displays the list on the display unit 34 (step A16).

Here, when the user checks the photographing order information which could not be transmitted and the list of the unsent image information and designates photographing order information corresponding to one unsent image information through the operation unit 35 (step A17) And the console 3 transmits a data request signal for requesting transmission of image data corresponding to designated photographing order information among unsent image data to the photographing device 2 (step A18). When the imaging device 2 receives the data request signal, the imaging device 2 reads the designated image data from the storage unit 25 (step A19), and transmits it to the console 3 (step A20).
When the console 3 receives the designated image data, it stores the image data, displays the radiation image, and transmits a notification of completion of data reception (steps A9 to A11), and the imaging device 2 deletes the image data (step A12). I do.

Here, the imaging order is specified one by one in the console 3 and the image data not linked is transmitted in the imaging device 2 and then transmitted to the console 3. However, the data request signal is transmitted, but not transmitted. The image data of the image data may be received at once and linked at the console 3.
In addition, although a plurality of photographing order information exists in one examination and transmission of the photographing order information (step A3) is performed for each photographing, the operation in the first step A3 has been described here. May be transmitted at once, and the second and subsequent steps A3 may not be performed. In this way, it is possible to cope with the case where the console 3 breaks down in the middle of the inspection.
Further, although the case where the series of operations from the imaging reservation (step A1) to the deletion of the image data (step A12) is performed twice has been described here, this series of operations may be performed only once. It may be repeated more than once.
Further, the image data generated in the unreserved state may be allocated from the list of the photographing order information.

(Modification 1)
In the above-described operation example, the transmitted image data is deleted for each photographing, but the transmitted image data may be collectively deleted from the storage unit 25 after the examination is completed.

In this case, the flow of inspection is as shown in FIG.
First, the operations of steps A1 to A11 are performed as in the above-described operation example. In step A7, transmission status information of "not transmitted" is linked to the image data.
Upon receiving the data reception completion notification, the imaging device 2 updates the transmission state information linked to the image data to "sent" (step A12A).

  Here, when the communication between the photographing device 2 and the console 3 is interrupted, the photographing device 2 can not transmit the image data to the console 3 (step A8 f). Therefore, the console 3 can not perform steps A9 to A11, and accordingly, the photographing device 2 can not perform step A12A. That is, the transmission state information linked to the image data remains "unsent".

Thereafter, when communication between the imaging device 2 and the console is restored, the console 3 and the imaging device 2 perform the operations of steps A13 to A11 as in the above-described operation example.
When the imaging device 2 receives the data reception completion notification, the imaging device 2 updates the transmission state information linked to the image data that has not been transmitted to "sent" (step A12A).
Thereafter, when the user instructs the end of the examination via the operation unit 35 (step A21), the console 3 transmits a data deletion signal for requesting deletion of the image data to the photographing apparatus 2 (step A22).
When the photographing device 2 receives the data deletion signal, the photographing device 2 collectively deletes the image data stored in the storage unit 33 for which the transmission state information is "sent" (step A23).

Here, the image data whose transmission status information is "sent" is deleted at once in response to an instruction to end the examination, but based on the fact that the storage capacity of the storage unit 25 falls below a predetermined value. It may be deleted automatically.
Further, although the case where the series of operations from the imaging reservation (step A1) to the update of the transmission state information (step A12A) is performed twice has been described here, this series of operations may be performed only once. It may be repeated three or more times.

(Modification 2)
In the above-described radiation image capturing apparatus 2, the control unit 21 has a function of causing the radiation detection unit 22 and the reading unit 23 to transition to the imaging standby state when receiving an instruction to start an examination from the console 3; A function may be provided to end the imaging standby state upon receiving an instruction to end the examination.

In this case, the flow of inspection is as shown in FIG.
First, when the user instructs the start of an examination via the operation unit 35 of the console 3 (step A31), the console 3 transmits a transition request signal requesting transition to the imaging standby state to the imaging device 2 (step A32) .
When the imaging device 2 receives the transition request signal, the imaging device 2 transitions to the imaging standby state (step A1).

After that, steps A2 to A9 are performed as in the above-described operation example and the first modification. Although FIG. 6 exemplifies a case where steps A1 to A9 are repeated twice after step A32, this series of operations may be performed only once or may be repeated three times or more.
Thereafter, when the user instructs the end of the examination via the operation unit 35 of the console 3 (step A21), the console 3 transmits an autonomous end signal requesting the end of the autonomous drive to the imaging device 2 (step A33).
When receiving the autonomous end signal, the imaging device 2 cancels the imaging standby state (step A34).

Although not shown in FIG. 6, after photographing, an operation related to deletion of image data (steps A11 and A12) similar to the above operation example, or an operation related to collective deletion of image data similar to the first modification. (Steps A11, A12A, A21 to A23) are performed.
Further, although not shown in FIG. 6, when communication between the console 3 and the photographing apparatus is interrupted and recovered thereafter, an operation regarding transmission of unsent image data similar to the above operation example or the first modification (step A13) To A12 or steps A13 to A12A) are performed.

(Modification 2A)
In the second modification, the instruction to start the examination is used as a trigger for transition to the imaging standby state, and the instruction to end the examination is used as a trigger for ending the imaging standby state. However, imaging is scheduled between the console 3 and the imaging device 2 The number of sheets may be exchanged, and the imaging standby state may be ended when the radiation detection unit 22 and the reading unit 23 finish generating the image data of the scheduled number of examinations.

In this case, the flow of inspection is as shown in FIG.
Specifically, after step A31, the console 3 transmits a state transition request signal to the imaging device 2, and also transmits the total number of radiographed radiation images in this examination (step A32A). In addition, although the case where the total number of shots is two is described here, it may be one or three or more.

Then, after step A2, the console 3 transmits the first photographing order information to the photographing device 2 (step A3A).
After that, steps A4 to A8 are performed as in the above-described operation example and the first modification.
Then, after step A8, the photographing device 2 checks the number of photographed images (step A35). Here, the total number of shots and the number of shots already taken are confirmed and both are compared. Here, if the number of captured images is less than the total number of captured images, the operation after step A1 is performed again.

Then, after the second step A2, the console 3 transmits the photographing order information of the two images to the photographing device 2 (step A3A).

Here, it is assumed that examination information indicating that three types of imaging of the chest front, chest side, and abdomen front are to be performed is transmitted.
When the imaging device 2 receives the examination information, the imaging device 2 transitions to the imaging standby state (step B3).
Thereafter, when the user designates a photographing order via the operation unit 35 of the console 3 (step B4), the photographing order information on the front of the chest, which is one of the plural photographing order information of the console 3, is transmitted to the photographing device 2 To do (step B5).
The photographing device 2 sets the received photographing order information (step B6). At this point in time, as shown in FIG. 14A, all the re-shooting status information, the shooting status information, and the transmission status information linked to each shooting order information are “(no re-shooting)” and “not yet It is "shooting", "not sent".

In this state, when the radiation irradiation apparatus 1 irradiates radiation toward the subject and the imaging apparatus 2 behind it (step B7), the imaging apparatus 2 detects the radiation and immediately accumulates (photographs) electric charge ( Step B8). Then, image data is generated (step B9), the generated image data is stored in the storage unit 33 (step B10), and the image data is transmitted to the console 3 (step B11). Then, the imaging state and the transmission state linked to the imaging order information on the front of the chest become "photographed" and "sent" as shown in FIG. 14 (b).
After step B11, the photographing device 2 shifts to the photographing standby state again (step B3).
When the console 3 receives the image data, the console 3 stores it in the storage unit 33 (step B12). Then, the console 3 displays a radiation image based on the received image data on the display unit 34 (step B13).
