Description

The present invention relates to a radiographic imaging system and a radiographic imaging apparatus constituting this system.

In recent years, a radiation imaging system equipped with a radiation device that generates radiation and a radiation imaging device that receives radiation and generates image data has been developed that supports not only still images but also moving images. There is. In such a system, the radiation apparatus and the radiation imaging apparatus are connected by a cable or the like, and a pulsed synchronization signal is transmitted to them a plurality of times for each imaging. Then, the radiation device and the radiation image capturing device repeat the radiation irradiation and the image data generation according to the synchronization signal, so that the moving image is captured.
Further, in order to facilitate compatibility with various imaging modes, there are an increasing number of cases where a portable type is adopted as a radiation imaging device constituting such a radiation imaging system.

By the way, in a facility (such as a large-scale hospital) equipped with a plurality of such radiographic imaging systems, the combination of the radiographic apparatus and the radiographic imaging apparatus may change for each imaging. However, not all of the plurality of radiation devices and radiation image pickup devices are compatible with moving image shooting. If a moving image is accidentally taken using a device that does not support moving image shooting, the desired moving image cannot be obtained and the subject is unnecessarily exposed to radiation.
Therefore, in recent years, when a radiographic imaging device (FPD) is loaded in a bucky device, the bucky device transmits the cassette ID and the bucky ID, which are identification information thereof, to the console, and images are taken based on the ID received by the console. A technique for determining the propriety of the above has been proposed (see Patent Document 1).

In addition, many portable radiographic imaging devices have a built-in battery so that imaging can be performed without receiving power from the outside. In order to suppress unnecessary power consumption, such a radiation image capturing device has, for example, a shootable mode in which shooting is possible, a power saving mode in which shooting is not possible although the amount of power consumption is small, and the like, as described in Patent Document 2. Many of them can be switched to.

Japanese Unexamined Patent Publication No. 2012-110451 Japanese Unexamined Patent Publication No. 2015-11258

In the radiographic imaging system described in Patent Document 1, a cassette ID and a bucky ID are transmitted to a console, the console determines whether or not video recording is possible based on these IDs, and then further video recording is performed by the user. Since the radiological imaging device is switched to the state in which it can be imaged for the first time upon receiving the instruction of, it takes a long time from the time when the radiographic imaging device is loaded in the bucky device until the actual imaging is performed, and it takes a long time for the user and the subject to be examined. It will make people wait.
In particular, in the case of a radiographic image capturing apparatus that switches to the power saving mode when shooting is not performed, as described in Patent Document 2, it takes more time to switch to the shooting mode.

The present invention has been made in view of the above points, and is connected to a radiation device that generates radiation and a radiation device by a cable, and radioimaging is performed based on a synchronization signal input via the cable. It is an object of the present invention to shorten the time from connecting the radiographic imaging apparatus to the radiographic apparatus to the state in which the radiographic imaging apparatus can be imaged in the radiographic imaging system including the apparatus.

[Structure of radiation imaging system]
First, the configuration of the radiographic imaging system 100 according to the present embodiment will be described. FIG. 1 is a schematic diagram showing a part of a facility in which the radiographic imaging system 100 according to the present embodiment is arranged.

It is configured so that it can be applied.
Although FIG. 1 shows a case where the exposure switch 13 is connected to the generator 12, it may be provided in the synchronization signal output unit 11 or an operation console (not shown).

The radiation source 14 (tube) has a rotating anode, a filament, and the like (not shown). Then, when a voltage is applied from the generator 12, the filament irradiates the rotating anode with an electron beam corresponding to the voltage, and the rotating anode generates a dose of radiation X corresponding to the intensity of the electron beam. ..
Further, the radiation source 14 is rotated by a rotation axis extending in the horizontal direction, and the irradiation port of the radiation is oriented in the horizontal direction (a state in which the image is taken in a standing position) or a state in which the irradiation port is directed in a vertically downward direction (a state in which the image is taken in a recumbent position). It is possible to switch to the state of performing.

The radiation imaging device 2 is connected to the synchronization signal output unit 11 of the radiation device 1, and when it receives radiation X, it accumulates charges corresponding to the intensity of radiation in a plurality of pixels, and the synchronization signal of the radiation device 1 is obtained. Each time a synchronization signal is input from the output unit 11, a signal value based on the amount of charge accumulated in each pixel is read out, and image data based on each signal value is generated. Then, the generated image data is retained by itself or transmitted to the console 3.
The radiation imaging apparatus 2 may be a dedicated machine type integrated with an imaging table or a portable type (cassette type), but it is preferably a portable type.
The details of the radiation imaging apparatus 2 will be described later.

The console 3 is composed of a computer, a dedicated device, and the like, and includes a control unit (not shown), a storage unit, and the like, as well as a display unit 31, an operation unit 32, and the like.

Further, the console 3 performs predetermined image processing on the image data received from the radiographic image capturing apparatus 2 to generate preview image data and diagnostic image data, and displays an image based on this data on the display unit 31. Is possible.
Although FIG. 1 shows a case where the console 3 is separate from the radiation device 1, the console 3 may be integrally configured with the radiation device 1.

When the radiation imaging system 100 is installed in a facility (hospital or the like), for example, as shown in FIG. 1, the synchronization signal output unit 11, the generator 12, the radiation source 14, and the radiation imaging device of the radiation device 1 are installed. The second and the like are arranged in the photographing room Ra, and the radiation switch 13 of the radiation device 1, the console 3 and the like are installed in the front room Rb (operation room) separated from the photographing room Ra.
When the radiation image photographing apparatus 2 is a portable type, as shown in FIG. 1, a cassette holder of an imaging table (an imaging table 4A for standing position photography and a photographing table 4B for lying position photography). It can be loaded into 41 and used. In this way, one radiographic image capturing device 2 can handle both standing and recumbent imaging.

In the radiation imaging system 100 configured in this way, when the user (radiologist or the like) operates the exposure switch 13 with the radiation imaging apparatus 2 loaded in the imaging tables 4A and 4B, the radiation apparatus 1 The synchronization signal output unit 11 transmits a pulsed synchronization signal to the generator 12 and the radiographic image capturing device 2, respectively. In response to this synchronization signal, the radiation device 1 irradiates the subject located in front of or above the radiation imaging device 2 with the radiation X under preset conditions, and the radiation imaging device 2 receives the subject. Generate image data of. That is, the radiation device 1 and the radiation imaging device 2 operate in synchronization with each other. In the case of moving image shooting in which the synchronization signal output unit 11 outputs a plurality of synchronization signals per shooting, irradiation of radiation X by the radiation device 1 and generation of image data by the radiation image shooting device 2 are repeated, and a plurality of times are performed. Movie data consisting of the frame image data of is generated.

[Connection between radiation device and radiation imaging device]
Next, the connection between the radiation device 1 and the radiation imaging device 2, which is a main part of the present invention, will be described. FIG. 2 is a block diagram of the radiation imaging system 100, and FIG. 3 is a perspective view of the radiation imaging device 2.

As shown in FIG. 2, the radiation device 1 of the present embodiment has an interface cable 15 (hereinafter referred to as a cable 15). The cable 15 can be configured by, for example, a LAN cable or the like, and has a plug 151 at the tip thereof. The base end of the cable 15 is fixed to the main body of the radiation device 1 (synchronization signal output unit 11 or the like). That is, the cable 15 of the present embodiment is dedicated to each radiation device 1, and is attached inseparably from the main body (so that it cannot be reused).
If there is no concern that the cable 15 may be confused, it may be removable.

Further, the plug 151 includes a chip 152 of a non-volatile memory (for example, EEPROM or the like) inside or on the surface thereof.
Further, a plurality of terminals 153 and 154 are formed on the plug 151. Some terminals 153 are connected to the signal line 155 (synchronous signal output unit 11) in the cable 15, and the remaining terminals 154 are connected to the chip 152.

The chip 152 (information storage means) stores a unique ID (identification information) for identifying each radiation device 1. The ID used in the present embodiment has a format in which the ID itself has no meaning, for example, a random enumeration of letters and numbers.
The format of the ID is not particularly limited, and may be a format that indicates the manufacturer, the presence / absence of the moving image shooting function, etc. for each digit.

In addition to the housing 21, the radiation imaging device 2 according to the present embodiment includes a control unit 22, a radiation detection unit 23, a reading unit 24, a storage unit 25, a communication unit 26, and an ID, which are housed in the housing 21. The interface 27, the connector 28, and the like are provided, and each part 22 to 27 is connected by a bus 29. Further, electric power is supplied to each unit 22 to 27 from a built-in power supply (not shown).

As shown in FIG. 3, a power switch 21a, a changeover switch 21b, an indicator 21c, and the like are provided on one side surface of the housing 21, and the connector 28 is exposed.

The control unit 22 is configured to comprehensively control the operation of each unit of the radiation imaging apparatus 2 with a CPU, RAM, or the like. Specifically, various types stored in the storage unit 25 based on the fact that the power switch is turned on, that a predetermined control signal is received from the radiation device 1, that radiation is received from the radiation device 1, and the like. The processing program is read out, expanded in RAM, and various processes are executed according to the processing program.

The radiation detection unit 23 may be any conventionally known one as long as it has a substrate in which a plurality of radiation detection elements that generate an amount of charge corresponding to the dose of radiation when receiving radiation have a substrate arranged in a two-dimensional manner. Can be used.
That is, the radiation imaging apparatus 2 may be a so-called indirect type that includes a scintillator and detects the light emitted by the scintillator receiving radiation, or the so-called direct detection of radiation without going through a scintillator or the like. It may be a direct type.

The reading unit 24 may be configured to be able to read out the amount of electric charge generated by each of the plurality of radiation detection elements as a signal value and generate image data based on each signal value, and conventionally known ones may be used. Can be used.

The storage unit 25 is composed of an HDD (Hard Disk Drive), a semiconductor memory, or the like, and stores various processing programs, parameters, files, and the like necessary for executing the program.
Further, the storage unit 25 can store the image data generated by the reading unit 24 in association with the subject information to be photographed and various shooting conditions.
Further, the storage unit 25 has a plurality of different IDs of the radiation device 1 and other radiation devices according to the present embodiment, and a shooting mode (still image shooting mode, moving image) in which the radiation device corresponding to each ID can be executed. The table to which the shooting mode) is associated is stored.

The communication unit 26 is composed of an interface circuit.
ID interface 27, for example, 1-wire is composed of a (R) or ^{I 2} C or the like.

The connector 28 is configured so that a cable 15 extending from the radiation device 1 can be inserted.
Further, the connector 28 is formed with a plurality of terminals 281,282 corresponding to the terminals 153 and 154 formed on the plug 151 of the cable 15, and some of the terminals 281 are connected to the communication unit 26. , The remaining terminals 282 are connected to the ID interface 27.

When the plug 151 of the cable 15 is inserted into the connector 28, a part of the terminal 153 of the plug 151 comes into contact with the part of the terminal 281 of the connector 28, and the communication unit 26 and the synchronization signal output unit 11 of the radiation device 1 Communication becomes possible, and the remaining terminals 154 of the plug come into contact with some terminals 282 of the connector 28, and the storage content (ID) of the chip 152 can be read by the control unit 22.

The control unit 22 of the radiation imaging apparatus 2 configured in this way operates as follows according to the processing program stored in the storage unit 25.
For example, the control unit 22 may cause the reading unit 24 to generate image data based on the amount of electric charge stored in each radiation detection element of the radiation detection unit 23 based on the reception of the synchronization signal by the communication unit 26. It is possible. That is, the control unit 22, the radiation detection unit 23, and the readout unit 24 function as image generation means in the present invention.
Further, the control unit 22 can store the generated image data in the storage unit 25 or transmit the generated image data to the outside using the communication unit 26. The image data may be output automatically as soon as the image data is generated, or may be output based on a request for transmission from the outside.

Further, when the plug 151 of the cable 15 is inserted into the connector 28, the control unit 22 acquires an ID via the cable 15 inserted into the connector 28. In this embodiment, the ID is directly read from the chip 152 embedded in the plug 151. That is, the control unit 22 functions as an information acquisition means in the present invention. Then, the control unit 22 recognizes that the cable 15 has been inserted into the connector 28 when the ID is read. That is, the control unit 22 also functions as a recognition means in the present invention.
Further, the control unit 22 can determine the type of the radiation device 1 connected by the cable 17 by referring to the table stored in the storage unit 25 after reading the ID. That is, the control unit 22 functions as a radiation device discriminating means in the present invention.

Further, the control unit 22 can change the state of the radiation detection unit 23 and the reading unit 24 (image generation means) to an exposure standby state (capable of photographing) in which electric charges can be accumulated in the radiation detection element and image data can be generated. It is possible to switch to a power saving state (state) in which image data cannot be generated due to a decrease in power consumption (state) or a power saving state (shooting impossible state). That is, the control unit 22 functions as a state control means in the present invention.
Specifically, when the control unit 22 is in the exposure standby state, a predetermined condition is satisfied (for example, a state in which an instruction to end shooting is received from the console 3 or a state in which a synchronization signal is not received is a predetermined period. Based on the above-mentioned continuation, etc.), the state of the radiation imaging apparatus 2 is switched to the power saving state.

Further, the control unit 22 is adapted to switch to the exposure standby state based on the recognition that the cable 15 has been inserted when the power saving state is in effect.
Further, when switching to the exposure standby state, the control unit 22 switches to the exposure-capable state corresponding to the discriminated radiation device 1 type among the plurality of types of imageable states.
Since there are two types of exposure standby states in the present embodiment, the exposure standby state in the still image shooting mode and the exposure standby state in the moving image shooting mode, the type of the discriminated radiation device corresponds to the still image shooting. If it is, the still image shooting mode is switched to the exposure standby state, and if it is compatible with movie shooting (radiation X is generated each time a synchronization signal is input), movie shooting is performed. Switch to the exposure standby state of the mode.

Next, the pre-shooting process executed by the radiographic image capturing device 2 will be described. FIG. 4 is a flowchart of pre-shooting processing.
This pre-shooting process is executed, for example, when the state of the radiographic image capturing device 2 is switched to the power saving state.

In this pre-imaging process, first, it is determined whether or not the plug 151 of the cable 15 is inserted into the connector 28, that is, whether or not the ID of the radiation device 1 can be acquired (step S1). This process of step S1 is repeated until it is determined that the plug 151 has been inserted (step S1; Yes).
In step S1, when it is determined that the plug 151 is inserted into the connector 28, that is, the ID of the radiation device 1 can be acquired (step S1; Yes), a process of recovering from the power saving state is performed (step S2). The type of the radiation device corresponding to the acquired ID, that is, whether or not the inserted cable 15 is compatible with moving image shooting is determined (step S3).

In step S3, when it is determined that the radiation device corresponding to the acquired ID does not support moving image shooting, that is, it corresponds to still image shooting (step S3; No), shooting is performed in the still image shooting mode. (Step S4). Then, the process shifts to the exposure standby state of the still image shooting mode (step S5), and the pre-shooting process is completed.

On the other hand, in step S3, when it is determined that the radiation device corresponding to the acquired ID is compatible with moving image shooting (step S3; Yes), it is determined whether or not the shooting information is input (step S6). ).
When it is determined in step S6 that the shooting information has been input (step S6; Yes), it is determined whether or not the shooting condition included in the input shooting information is moving image shooting (step S7).
If it is determined in step S7 that the shooting condition is not moving image shooting, that is, still image shooting (step S7; No), the process proceeds to step S4 described above.

When it is determined in step S6 that the shooting information has not been input (step S6; No), or when it is determined in step S7 that the shooting condition is moving image shooting (step S7; Yes), the moving image shooting mode is used. A preparatory process for shooting is performed (step S8). Then, it is determined whether or not the shooting information has been input (step S9). This process of step S9 is repeatedly executed until it is determined that the shooting information has been input (step S9; Yes).
When it is determined in step S9 that the shooting information has been input (step S9; Yes), it is determined whether or not the shooting condition included in the input shooting information is moving image shooting (step S10).

If it is determined in step S10 that the shooting condition is not moving image shooting, that is, still image shooting (step S10; No), the process proceeds to step S4 described above.
On the other hand, if it is determined in step S10 that the shooting condition is moving image shooting (step S10; Yes), the process of step S5 described above is performed, and the pre-shooting process is terminated.
In the pre-shooting process of the present embodiment, the number of steps when shooting a moving image is larger than that when shooting a still image, but the preparatory process for shooting a moving image takes time, and the preparatory process for shooting a still image is Since it can be done in a short time, it is possible to reduce the waiting time of the user even in this flow.

As described above, the radiation imaging system 100 according to the present embodiment includes a radiation device 1 having a radiation source 14 capable of generating radiation, an image generation means capable of generating image data, and a cable extending from the main body of the radiation device 1. The state of the connector 28 into which the 15 can be inserted, the recognition means for recognizing that the cable 15 has been inserted into the connector 28, and the state of the image generation means can be changed to an exposure standby state (photographable state) or an image capable of generating image data. The state control means includes a state control means for switching to a power saving state (imaging impossible state) in which data cannot be generated, and a radiographic image capturing apparatus 2 having the state control means, when the image generation means is in the power saving state. Based on the recognition by the recognition means that the cable 15 has been inserted, the state is switched to the exposure standby state.

In the past, the console was used to determine the type of radiation device or radiation imaging device, and after receiving instructions from the user, the process was performed to switch from the power saving state to the exposure standby state. I had to wait a relatively long time for the switch to complete. However, according to the present embodiment, as soon as the radiation imaging device 2 is connected to the radiation device 1, the radiation imaging device 2 is switched to the exposure standby state corresponding to the radiation device 1. It is possible to shorten the time from the connection with the radiation apparatus 1 until the radiation imaging apparatus is in the exposure standby state, and it is possible to improve the usability of the radiation imaging system and the efficiency of examination.
Further, since the preparation process for moving image shooting can be started immediately after the cable 15 is inserted into the connector 28 of the radiation image capturing device (image generation means), the preparation process is started after receiving the user's instruction as in the conventional case. It is possible to spend more time on the preparatory process without increasing the waiting time of the user or the subject as compared with the case of doing so. As a result, it becomes possible to take a picture after the state of the radiation image taking device is sufficiently prepared, so that the image quality of the moving image can be improved.

<Second Embodiment>
Next, a second embodiment of the present invention will be described.
Here, only the differences from the first embodiment will be described, and the description of the common configuration will be omitted.

FIG. 5 is a block diagram showing the configuration of the radiation imaging system 100A according to the present embodiment.
In the first embodiment, the cable 15 is inseparable from the main body of the radiation device 1, and the chip 152 for storing the ID is provided in the plug 151 of the cable 15. However, the radiation acquisition line according to the present embodiment is provided. As shown in FIG. 5, the imaging system 100A is provided with the chip 16 in the main body of the radiation device 1A.
The cable 15A in the present embodiment may be inseparable from the radiation device 1A or may be separable.

Along with this, the radiation apparatus 1A according to the present embodiment is adapted to transmit the ID stored in the chip 16 from the ID interface 17 to the radiation imaging apparatus 2A via the cable 15A. That is, the chip 16 and the ID interface 17 function as transmission means in the present invention.

The ID used in this embodiment has a format that indicates the manufacturer, the presence / absence of a moving image shooting function, etc. for each digit.
In addition, also in this embodiment, the format of the ID is not particularly limited, and the ID itself may be a format having no meaning, such as a random enumeration of characters and numbers as in the first embodiment.

Further, the cable 15A according to the present embodiment includes a signal line 156 for transmitting an ID separately from the signal line 155 for transmitting a synchronization signal. The tip of the signal line 156 is connected to the terminal 154 of the plug 151.
In addition, instead of providing the signal line 156 for transmitting the ID to the cable 15A, the ID interface 17, the radiation imaging device 2, and the cable 15A may be connected by a different cable to transmit the ID. ..

Further, the storage unit 25A of the radiation imaging device 2A according to the present embodiment does not store a table for comparing the ID and the radiation device 1 or a program for the control unit 22 to refer to the table.
Then, after reading the ID, the control unit 22 directly identifies the type of the connected radiation device from the read ID without referring to the table.
Further, the ID interface 27 receives the ID transmitted from the radiation device 1A through the cable 15A.

By doing so, it is not necessary to make the cable 15A unique to each radiation device 1, so that the cable 15A can be reused, and a radiation image is taken every time the radiation device 1 is updated with a new one. There is no need to store a new table in the device 2.
In this embodiment as well, as in the first embodiment, the ID may be a random enumeration of characters and numbers and may be identified based on a table.

Although the present invention has been specifically described above based on the embodiment, the present invention is not limited to the above embodiment and can be changed without departing from the gist thereof.
