In addition, the radiological image detection apparatus 1 incorporates a wireless communication unit 19 that performs directional wireless transmission and wireless reception, as will be described later. A wireless communication unit 41 of the network 4 is provided ahead of the directivity direction 42. The radiological image detection apparatus 1 is connected to the network 4 via the wireless communication unit 41. In FIG. 2, as an example, the device configuration around the imaging bed 50 for the lying position imaging in which the imaging is performed with the patient lying on the table is shown, but the imaging is performed with the patient standing. The present invention can also be applied to an apparatus configuration for standing imaging performed, an apparatus configuration of the radiation image detection apparatus 1 alone, or a combination thereof.

  The radiation image detection apparatus 1 of this embodiment is demonstrated.

  The radiation image detection apparatus 1 is a cassette type FPD (Flat Panel Detector) in which an FPD (Flat Panel Detector) is accommodated as the flat detector 12. In this embodiment, an example in which the radiation image detection device 1 is a cassette type FPD (Flat Panel Detector) will be described. However, the radiation image detection device 1 has an FPD (Flat Panel Detector) as a flat detector. It is not limited to the cassette type.

  FIG. 3 is a block diagram showing a main configuration of the radiological image detection apparatus 1 according to the present embodiment. As shown in FIG. 3, the radiological image detection apparatus 1 includes a flat detector 12. The flat detector 12 is image data acquisition means for outputting the radiation image data by a plurality of solid state light detection elements arranged in a two-dimensional manner.

  In radiographic image detection apparatus 1, at the time of radiography, the plane detection unit is disposed in the irradiation field of radiation source 10 so as to face the imaging region of the patient, and detects the radiation emitted from radiation source 10.

  Here, although not shown in the figure as the flat detector 12, for example, on a predetermined substrate such as a glass substrate, a radiation light conversion layer that converts radiation into fluorescence, and fluorescence converted by the radiation light conversion layer An indirect type having a photoelectric conversion layer that detects and converts it into an electric signal, and a direct type having a radiation charge conversion layer that converts radiation directly into electric charge instead of the radiation conversion layer and the photoelectric conversion layer Any of these may be used. Then, each solid-state light detection element of the flat detector 12 is converted into an electric charge and accumulated according to the intensity of the radiation irradiated from the radiation source 10 and transmitted through the patient 6, and is read out by the read signal. Output data. This radiographic image data represents a radiographic image that is an intensity distribution of the radiation transmitted through the patient 6.

  Furthermore, the radiation image detection apparatus 1 is provided with an image memory 14 that can store radiation image data corresponding to a plurality of radiation images. The image memory 14 temporarily stores radiation image data detected by the flat detector 12, and is composed of, for example, a nonvolatile memory such as a flash memory. Since the image memory 14 can store radiographic image data corresponding to a plurality of radiographic images, as described later, when the transmission of the radiographic image data to a specific controller is not normally completed, the image memory 14 can store the radiographic image data. Until the transmission, another radiation image data can be stored by another radiation imaging. In addition, when the memory has such a large capacity, it is not necessary to send the radiation image data to the controller 2 for each imaging, and a plurality of imaging can be performed continuously.

Furthermore, the radiation image detection apparatus 1 is provided with a display unit 20 that displays that the communication state between the radiation image detection apparatus 1 and the network 4 is poor. This display only needs to allow the operator to recognize that the communication state is poor. For example, the display may be a visual display such as a liquid crystal display or an LED display, or an auditory display such as a warning sound. Or other display may be used.
The radiological image detection apparatus 1 also includes a power source 15 that supplies power to the flat detector 12, the communication unit 13, the image memory 14, the detection device control unit 17, and the display unit 20. The power supply unit 15 includes a rechargeable battery 16 and is configured to be rechargeable via a charging terminal (not shown) provided at a predetermined position of the radiological image detection apparatus 1. Thus, by providing the radiographic image detection apparatus 1 with the power supply unit 15, the radiographic image data can be continuously output and the radiographic image data can be transmitted even if the radiographic image detection apparatus 1 is not always connected to an external power supply by a cable or the like.

The radiological image detection apparatus 1 is provided with the above-described flat detector 12, communication unit 13, image memory 14, power supply unit 15, and detection device control unit 17 that controls the display unit 20.

Detecting means for detecting whether or not the transmission of the radiation image data to the specific controller 2 has been normally completed, and at least one of cases where the detection means has not detected that the transmission has been normally completed. In this case, the transmission means functions as a transmission control means for transmitting to a controller different from the specific controller 2. Then, when at least part of the case where the detection means does not detect that the transmission has been normally completed, the radiation image data is transmitted to one of these controllers based on a predetermined order. Let
In addition, the program stored in the storage unit 18 includes a corresponding unit that associates the detection device control unit 17 that is a computer with an operator ID and a radiographic image transmitted from the controller 2, as will be described later. And means for detecting whether or not the transmission of the radiographic image data to the specific controller 2 has been normally completed after starting to transmit the radiographic image data to the specific controller 2. In at least a part of the case where the detection means does not detect that the detection has been completed normally, the operator ID associated with the radiation image is assigned to the controller 2 that is the operator ID of the operator currently in use. The communication unit 13 of the radiation image detection apparatus 1 functions as a transmission control unit that causes the radiation image data of the radiation image to be transmitted. Than is.

Note that the detection device control unit 17, the plane detection unit 12, the communication unit 13, the image memory 14, and the power supply unit 15 are connected by a bus 30.
Further, the detection device control unit 17 detects whether or not the radiation image data has been normally transmitted to the controller 2. Further, it is detected whether another abnormality has occurred, such as a transmission abnormality on the radiation image detection apparatus 1 side. Specifically, the detection device control unit 17 measures the elapsed time from the start of transmission of the radiation image data to the controller 2, and does not receive the reception completion signal from the controller 2. When elapses, it is determined that the transmission of the radiation image data to the controller 2 has not been completed normally.

  Here, the reference time is a variation of a general time taken from the start of transmission of radiation image data from the radiation image detection apparatus 1 to the controller 2 until reception of a reception completion signal from the controller 2. And may be a fixed time, or may be a time varying or different depending on conditions such as the distance from the radiation image detection apparatus 1 to the controller 2 and the type of the controller 2 on the receiving side. . This specific reference time is preset and stored in the storage unit 18 of the detection device control unit 17. In the present embodiment, the detection device control unit 17 reads out the reference time from the storage unit 18 and compares it with the measured elapsed time to determine whether or not the reference time has elapsed from the time of transmission.

  When it is determined that the radiographic image data could not be transmitted normally, the detection device control unit 17 determines whether the cause of the further failure in transmission is the radiographic image detection device 1 side or the controller 2 side. If the cause is determined to be on the controller 2 side, the detection device control unit 17 controls the communication unit 13 to respond to an operator who has performed radiographic imaging with another controller 2. The controller 2 in which the operator ID to be registered is made to perform transmission processing for transmitting radiation image data and the like.

  When the radiographic image data is normally transmitted to the controller 2, the radiographic image detection confirmation program receives an electric signal (hereinafter, referred to as completion of reception) from the communication unit 22 of the controller 2 to the detection device control unit 17. When the reception completion signal from the controller 2 is received, the detection device control unit 17 transmits the radiation image data stored in the image memory 14. Erase the radiation image data of the already completed one The radiographic image data may be transmitted to the controller 2 for each radiographing, and the radiographic image data stored in the image memory 14 may be sequentially deleted from the completed transmission, or a plurality of radiographic image data may be deleted. When a large-capacity memory that can be stored is provided, the radiographic image data is transmitted to the controller 2 every time when all imaging for one patient 6 is completed or every time a certain number of imaging is completed, and the transmission is completed. The radiation image data stored in the image memory 14 may be sequentially deleted.

Examples of such portable storage media and storage medium readers include, but are not limited to, barcodes and barcode readers, magnetic cards and magnetic card readers, and IC cards and IC card readers.

  Moreover, you may make it search the matching information from HIS and RIS with patient ID. In this case, the patient may have a portable storage medium storing the patient ID, and a storage medium reader may be provided to read the information from the portable storage medium brought by the patient. Alternatively, input from the input operation unit 27 may be performed, or patient-specific information such as a fingerprint or a voiceprint is stored in the HIS or RIS, and a fingerprint detection device or a voiceprint detection device is provided in the controller 2 to detect the detected fingerprint. Information matching by voiceprints or voiceprints may be retrieved from HIS or RIS.

  Next, radiation image detection processing of a radiation image in the radiation image detection confirmation network system and the radiation image detection confirmation program according to the present embodiment will be described.

  When radiographing is performed, the operator inputs advance information such as patient information and imaging conditions of the patient to be imaged from the input operation unit 27 of the controller 2, and these information are transmitted via the network 4. It is transmitted to the radiation irradiation control device 11 and the detection device control unit 17 of the radiation image detection device 1.

  The operator arranges the imaging region of the patient as a subject at a predetermined position in the irradiation field of the radiation source 10 and causes the display unit 21 of the controller 2 to display the patient information and imaging information as appropriate. The operator operates the radiation irradiation control device 11 while confirming these pieces of information, and irradiates the patient 6 with a predetermined amount of radiation from the radiation source 10. Patient information, imaging information, and the like may be displayed on the display unit of the radiation irradiation control device 11 instead of the display unit 21 of the controller 2.

  At this time, the radiation image detection apparatus 1 is mounted below the patient, detects the amount of radiation that passes through the patient 6, converts the detected radiation into an electrical signal, and acquires radiation image data of the radiation image. The radiation image data acquired by the radiation image detection device 1 is temporarily stored in the image memory 14 and then transmitted to the specific controller 2.

  Next, a transmission processing flow of the radiological image detection apparatus according to the present embodiment will be described with reference to FIG. FIG. 5 is a flowchart showing a transmission process of the radiological image detection apparatus of the present embodiment.

  Each controller 2 associates patient information, imaging information, operator ID (identification information unique to the operator) and the like input before radiography with the radiation image ID (= identification information unique to the radiographic image) to the server 3. And save. Then, the controller ID of the controller 2 (= identification information unique to the controller), the operator ID, and the radiographic image ID are transmitted to the radiographic image detection apparatus 1 that outputs radiographic image data by radiography.

  Then, the detection device control unit 17 of the radiation image detection device 1 receives the controller ID, the operator ID, and the radiation image ID from the controller 2 via the network 4. Thereafter, the radiological image detection apparatus 1 obtains radiographic image data by radiography. The detection device control unit 17 of the radiation image detection device 1 associates the obtained radiation image data with the received controller ID, operator ID, and radiation image ID.

And the detection apparatus control part 17 of the radiographic image detection apparatus 1 specifies and transmits a transmission destination controller based on the information registered before transmission by a transmission processing program. In this embodiment, the specific controller 2 which becomes a transmission destination of radiation image data is specified based on the received controller ID, and is transmitted. (Step S1) Here, the detection device control unit 17 controls the communication unit 13 to transmit the radiation image data to the controller 2, and the detection device control unit 17 has successfully transmitted the radiation image data to the controller 2. Detect. Further, it is detected whether another abnormality (referred to as another abnormality) such as a transmission abnormality on the side of the radiation image detection apparatus 1 has occurred.
When the detection device control unit 17 of the radiological image detection device 1 detects that the radiographic image data has been normally transmitted to the controller 2, the transmission processing is terminated. If it is detected that another abnormality has occurred, the transmission process is stopped.
However, when it is not detected that the radiographic image data has been normally transmitted to the controller 2 and it is not detected that another abnormality has occurred, the detection device control unit 17 of the radiographic image detection device 1 uses the transmission processing program. The controller holding the operator ID corresponding to the radiation image data is specified and transmitted. (Step S2)
This is because, when the reception state of the controller 2 in which the information related to the radiation image is registered becomes abnormal, the operator recognizes it and the operator moves to any other controller 2, and the operator of the controller 2 This is a flow assuming that the operator ID is input from the ID input unit 26 and the operation / image confirmation is performed. This step S2 can cope with this.

When the detection device control unit 17 of the radiation image detection device 1 acquires the operator ID registered in the controller 2 via the network 4 and confirms that the operator ID corresponds to the operator who performed the imaging, the operator ID is Radiation image data is transmitted to the registered controller 2.
In this case as well, the detection device control unit 17 controls the communication unit 13 to transmit the radiation image data to the controller 2, and the detection device control unit 17 detects whether the radiation image data can be normally transmitted to the controller 2. . Further, it is detected whether another abnormality has occurred, such as a transmission abnormality on the radiation image detection apparatus 1 side.
When the detection device control unit 17 of the radiological image detection device 1 detects that the radiographic image data has been normally transmitted to the controller 2, the transmission processing is terminated. If it is detected that another abnormality has occurred, the transmission process is stopped.
However, when it is not detected that the radiographic image data has been normally transmitted to the controller 2 and it is not detected that another abnormality has occurred, the detection device control unit 17 of the radiographic image detection device 1 uses the transmission processing program. The controller is specified and transmitted in a predetermined order. (Step S3) Again, the detection device control unit 17 controls the communication unit 13 to transmit the radiation image data to the controller 2, and the detection device control unit 17 has successfully transmitted the radiation image data to the controller 2. Detect. Further, it is detected whether another abnormality has occurred, such as a transmission abnormality on the radiation image detection apparatus 1 side.

  As a modification of the present embodiment, step S2 may be omitted and step S1 followed by step S3. Specifically, the priority order of the transmission destination controller 2 that transmits the radiation image data is determined in advance, and when the controller 2 specified first is unsuitable for communication, the detection device control unit 17 determines the radiation image data. The radiographic image data may be transmitted according to this order without checking the controller corresponding to the operator ID corresponding to. As a result, time for confirming the operator ID becomes unnecessary, and image transmission and confirmation can be performed earlier. This is because when the reception state of the controller 2 in which the information related to the radiation image is registered becomes abnormal, the operator recognizes it and moves the operator to another controller 2 in a predetermined order. This flow assumes that the image is confirmed. This step S2 can cope with this.

  Next, the subflow of each processing step will be described based on FIG. 6 which is a flowchart of the subflow in each processing step of the transmission processing flow.

  Upon entering each processing step, the following subflow starts (step S11). The detection device controller 17 of the radiation image detection device 1 selects the controller 2 that is the transmission destination of the radiation image data by the method for each processing step described above (step S12). The detection device control unit 17 of the radiological image detection device 1 controls the communication unit 13 to transmit the radiation image data from the communication unit 13 to the selected specific controller 2. At the same time, the detection device control unit 17 starts measuring the elapsed time from the time when the radiation image data is transmitted (step S13). And the detection apparatus control part 17 detects whether the communication part 13 received the reception completion signal (step S14). The reception completion signal is a reception completion signal that is returned to the radiological image detection apparatus 1 when the controller 2 normally receives the radiographic image data.

  When the communication unit 13 receives the reception completion signal, the detection device control unit 17 determines that the transmission is normally completed, and deletes the radiation image data stored in the image memory 14 (step S15).

  As a modification of the present embodiment, the detection device control unit 17 may not erase the radiation image data in the image memory 14 for a while even after confirming the signal from the controller 2. In this case, the radiation image data can be transmitted again when it is later determined that there is an abnormality in the transmitted radiation image data, or when the transmitted radiation image data is lost. When the specific controller 2 normally receives the radiation image data, the image transmitted to the display unit of the controller 2 is displayed, and the operator can check the image.

  And when the communication part 13 has not received the reception completion signal, the detection apparatus control part 17 judges whether the preset predetermined time passed from the time of transmitting radiographic image data (step S16). As a result, when it is determined that the predetermined time has not elapsed, the process returns to step S14. As a result, if it is determined that the predetermined time has elapsed, it is determined that the transmission has not been completed normally (step S17). In this case, it is further detected whether or not the communication state between the radiological image detection apparatus 1 and the network 4 is good (step S18).

  When it is detected that the communication state between the radiological image detection apparatus 1 and the network 4 is not good, that is, when it is detected that the above-described another abnormality has occurred, the cause of the transmission not being performed normally is the radiographic image. Since there is a problem on the detection device 1 side, the detection device control unit 17 controls the display unit 20 to display that the communication state of the radiation image detection device 1 is defective (step S19). Then, the entire transmission process is stopped.

  On the other hand, when it is not possible to detect whether or not the communication state between the radiation image detection device 1 and the network 4 is good, or when it is detected that the communication state of the radiation image detection device 1 is good, transmission is normal. Since there is a possibility that the cause of the failure is not on the controller 2 side, the process proceeds to the next processing step (step S20).

  As described above, according to the radiological image detection confirmation network system according to the present embodiment, even when one identified controller 2 is in a transmission disabled state, an operator ID corresponding to the controller 2 or a predetermined ID is determined. By selecting and transmitting another controller 2 as a transmission destination of the radiation image data in accordance with the order in which they are transmitted, the radiation image data acquired by the radiation image detection apparatus 1 is used for the display unit 21 of the other controller 2. The confirmation image is displayed, and the operator can confirm the radiation image represented by the radiation image data.

  In the present embodiment, if the transmission of the radiation image data to the specific controller 2 selected as the transmission destination of the image information is not normally completed and it is not detected that another abnormality has occurred, The radiographic image data is transmitted only to the specific controller 2, but as a modification thereof, the transmission of the radiographic image data to the specific controller 2 is not normally completed and it is not detected that another abnormality has occurred. In this case, the radiation image data may be transmitted to all other controllers 2. Thereby, the confirmation image corresponding to the radiation image represented by the radiation image data can be displayed in any controller 2, and the operator can confirm the radiation image data in any controller 2.

In the present embodiment, (1) from the operator ID acquired by the operator ID input unit 26 of the controller 2, the controller 2 and the operator ID of the operator currently in use of the controller 2 are obtained. The association is performed by each controller 2, (2) the operator ID transmitted from the controller 2 is associated with the radiation image, and (3) the operator ID associated with the radiation image is currently in use. The controller that is the operator ID of each operator is specified by the detection device control unit 17 of each radiation image detection device 1.
As a modification to this, in the server 3, (1) from the operator ID acquired by the operator ID input unit 26 of the controller 2, the operator of each controller 2 and the currently used operator of the controller 2. (2) The operator ID transmitted from the controller 2 is associated with the radiographic image, and (3) the operator ID associated with the radiographic image is that of the operator currently in use. The controller that is the operator ID may be specified. As a result, all information can be concentrated on the server 3 and batch management becomes easy.

In this case, when the controller 2 initially specified as the transmission destination cannot be transmitted, the radiological image detection apparatus 1 is registered in the server 3 with the corresponding operator ID registered in the server 3 or in advance. A signal instructing to notify the controller ID of the controller 2 selected by the priority order is transmitted, and based on this signal, the server 3 transmits the controller ID to the radiation image detection apparatus 1.
Further, in the server 3, (1) each controller 2 is associated with the operator ID of the currently used operator of the controller 2 from the operator ID acquired by the operator ID input unit 26 of the controller 2. (3) The operator ID associated with the radiographic image identifies the controller that is the operator ID of the operator currently in use, and the radiographic image detection apparatus 1 (2) The operator ID transmitted from the controller 2 may be associated with the radiation image.

  Further, the present embodiment is limited to a case where information such as correspondence between radiographic image ID, controller ID, and operator ID and imaging conditions is directly acquired from the controller 2 to the radiographic image detection apparatus 1 via the network 4. Instead, the data may be transmitted to the server 3 via the network 4 and stored, and then transmitted from the server 3 to the radiation irradiation control device 11 and the radiation image detection device 1.

  In this embodiment, whether or not the transmission of the radiation image data to the specific controller 2 has been normally completed is determined based on whether or not the reception completion signal transmitted from the controller 2 has been received within a predetermined time. However, the determination as to whether or not the transmission of the radiation image data to the specific controller 2 has been normally completed is not limited to this. For example, between the radiation image detection device 1 and the specific controller 2 It may be determined whether or not the transmission has been normally performed by detecting whether or not the communication has been established.

  In this embodiment, it is determined that the radiation image data has not been transmitted normally when a predetermined time has elapsed since the radiation image data was transmitted to the controller 2. Is not limited to the elapsed time from the time of transmission. For example, it may be determined based on the elapsed time from the end of transmission, or from the controller 2 selected as the transmission destination. If there is no response, it may be determined immediately that transmission has failed.

  The image memory 14 itself may be a portable memory that is detachable from the main body of the radiation image detection apparatus 1. Examples of the portable memory in this case include, but are not limited to, a memory card, a memory stick, and a portable silicon disk. The radiation image detector 3 is provided with slots (not shown) corresponding to these.

As a result, even when the communication state between the radiation image detection apparatus 1 and the network 4 is not good, the operator can carry the portable memory to the controller 2 and attach it to the predetermined attachment position of the controller 2, so that the worst radiation Radiation image data obtained by imaging can be taken into the controller 2.
The portable memory may have a small capacity that can store only radiation image data for one radiation image, but has a large capacity that can store radiation image data of a plurality of radiation images. Some are preferred.

In addition to the image memory 14, the radiation image detection apparatus 1 may be equipped with a portable memory that is detachable from the main body of the radiation image detection apparatus 1. When the portable memory is mounted, the radiation image data output from the plane detection unit 13 may be stored simultaneously with the image memory 14, but the radiation image data output from the plane detection unit 13 is stored in the image memory 14. It is preferable to store the radiation image data once stored in the image memory 14 and transferred to the portable memory.
Thereby, even when the communication state between the radiological image detection apparatus 1 and the network 4 is not good, the radio image data obtained by radiography can be taken into the controller 2 at worst, and the portable type has a low storage speed. The memory becomes rate-determined, the signal reading speed of the flat surface detection unit 13 becomes slow, and it can be suppressed that noise is added to the output radiation image data.

  In addition, it is needless to say that the present invention is not limited to the above embodiment and can be modified as appropriate.
