Description

  The present invention relates to a radiation imaging system that irradiates a subject with radiation and acquires radiation image data based on the amount of radiation that has passed through the subject, and particularly relates to a radiation imaging system and a radiation image detection device that are connected via a communication line.

  In recent years, a digital radiological image detection apparatus has been used as a method for obtaining a radiographic image by irradiating a subject with radiation and detecting the radiation transmitted through the subject. As such a radiation image detection apparatus, there is a so-called FPD (Flat Panel Detector).

  As an example of an FPD, a plurality of detection elements are two-dimensionally arranged on a substrate, radiation that has passed through a subject is irradiated on a phosphor (scintillator), and visible light that emits light according to the amount of irradiated radiation is emitted. There is one that obtains a radiographic image by converting electric charge into a capacitor by a detection element and accumulating it in a capacitor and reading out the electric charge accumulated in the capacitor. Such an FPD has immediacy that a radiographic image can be obtained immediately after imaging.

  Also, in recent years, from the viewpoint of convenience of information use and speed of various processes, HIS (Hospital Information System) is managed as a system for centrally managing patient diagnosis information and accounting information, and radiographing order information in radiology is managed. RIS (Radiology Information System) and the like have been introduced as a system. Various radiographic image capturing apparatuses, control terminals of the image capturing apparatuses, and the like are connected to the RIS and the HIS via a network such as a LAN disposed in the hospital.

  A radiation imaging system in which a plurality of consoles (control terminals) and a plurality of FPDs having a communication function are connected to such a hospital network is disclosed (see Patent Document 1). In the radiation image system described in Patent Document 1, in order to improve the efficiency of image confirmation by an operator such as a radiologist or a doctor, an imaging order is transmitted and registered to the FPD selected from the console before imaging, After imaging, the radiographic image is transmitted from the FPD to the console that has performed the registration. As a result, the operator can check the radiographic image by returning to the console that has registered the imaging order after imaging.

In addition, since the portable cassette type FPD can store a plurality of radiation images in its internal memory, it can be used by registering a plurality of imaging orders at a time and performing a plurality of imaging continuously. It has become.

The “vacant” state is a state that is not “accepting”, and the control terminal from the time when all the radiation image data related to the imaging reservation is acquired or the time when the acquired radiation image data is completely transmitted to the control terminal CS. This is until the photographing reservation is received from the CS. These reception states are stored in the memory F3. When the acceptance state is “accepting”, the control terminal ID information of the control terminal CS that has transmitted the accepted photographing reservation is stored in the memory F3 together with the acceptance state and the number of photographed images. In other words, the control unit F1 has functions of a “shooting reservation receiving unit”, a “shooting state control unit”, and a “reception control unit”, and the memory F3 functions as a “storage unit”.

Or remember. Further, in order to identify each control terminal CS, the control terminal CS is given unique “control terminal ID” information and stored in the memory C3 in advance.

  FIG. 3 is a schematic diagram of the radiation imaging system according to the embodiment. As shown in the figure, the radiation imaging system includes irradiation devices R1 and R2 and a plurality of radiation image detection devices F1 to F4 (hereinafter referred to as FPD1 to FPD4 or simply referred to as FPD) shown in FIG. A plurality of control terminals CS1 to CS4 are connected to the same communication line N. The FPD 1 and FPD 2 in the radiation room 1 are connected to the communication line N by a wireless method, but the FPD 3 and FPD 4 in the radiation room 2 are wired via a connector 35 and a cradle (not shown). It is connected to the communication line N by the method.

  FIG. 4 is a diagram illustrating a control flow of the radiation imaging system according to the embodiment. The control flow between control terminals CS and FPD operated by an operator such as a radiologist or a doctor is shown.

  First, in step S0, a photographing order executed by the irradiation device R and the FPD is selected from a plurality of photographing orders held in the memory C3 of the control terminal CS.

  FIG. 5 shows an example of a plurality of imaging orders stored in the memory C3 of the control terminal CS. As shown in FIG. 5, each imaging order is assigned a unique imaging order ID (p1), and each imaging order has a patient ID (p2), a department (p6), an imaging region (p7), and an imaging direction. Information on the imaging condition (p8) is given. Since patient information such as patient name (p3), sex (p4), age (p5), and the like is associated with the patient ID (p2), the information is also given. The patient information is for specifying a patient, and by identifying the patient, the patient information is prevented from being mixed with other patients. For example, the imaging order ID “61201001” indicates that the department is a surgery department, and that Ichiro Suzuki with the patient ID “100085” performs imaging of front AP on the chest.

  Since a list of shooting orders as shown in FIG. 5 is displayed on the display screen of the operation display unit C5 of the control terminal CS, the operator selects a shooting order ID (p1) for shooting from the displayed shooting orders. To do. The imaging order may be input directly by the operator from the operation display unit of the control terminal CS, or the imaging order registered in the radiation management server or in-hospital information system HIS, not shown, is received. You may make it do.

  In step S1, the control terminal CS requests one of the FPDs to make a shooting reservation. At this time, the control terminal ID information of the control terminal CS and the number of shots are also transmitted.

  In the FPD that has received the imaging reservation request, the control unit F1 refers to the reception state stored in the memory F3, and if the current reception state is “accepting” (Yes in step S2), the reception of the imaging reservation is received. Is rejected (step S3). The control terminal CS that has received the reply of acceptance rejection (step S4) performs the flow from step S1 onward again to request another FPD other than the FPD for which acceptance has been rejected to accept the imaging reservation again.

  On the other hand, if the accepting state is not the “accepting” state (No in step S2), the control unit F1 sets the FPD state to the “accepting” state, that is, stores the accepting state of “accepting” in the memory F3. Then, the control terminal ID of the control terminal CS that has transmitted the number of shots and the shooting reservation is stored in the memory F3 (step S6), and the shooting reservation is accepted for the control terminal CS that has transmitted the shooting reservation. A reply (acceptance permission) is returned (step S7). Thereafter, no other imaging reservation is accepted until the “accepting” state is canceled.

  The control terminal CS registers the photographing order and the ID number of the FPD that received the reception (step S8) upon completion of reception permission, and ends.

  In the radiation imaging system in which a plurality of consoles and a plurality of FPDs are connected on the same communication line as described above, when the imaging reservation from one control terminal device is being accepted, By not accepting other imaging reservations, it is possible to prevent a single FPD from being registered redundantly by a plurality of consoles, and thus to prevent a radiographic image corresponding to a patient from being mixed up. A detection device can be obtained.

  In the present embodiment, the imaging reservation, the number of images to be captured, and the control terminal ID are transmitted from the control terminal CS to the FPD, and the imaging state, the number of images to be captured, and the control terminal ID are stored in the memory F3 of the FPD. However, an imaging order including information such as a patient ID and an imaging region may be transmitted from the control terminal CS, and the transmitted imaging order may be stored in the memory F3. In this case, it becomes possible to display the imaging order on the display unit 33 of the FPD, and the operator can confirm the imaging order immediately before the radiographic imaging, thereby preventing the radiographic image corresponding to the patient from being mistaken. It becomes possible.

  FIG. 6 is a diagram illustrating a control flow of a radiation imaging system according to another embodiment. The flow shown in the figure is obtained by adding the flow in the broken line frame A to the flow in FIG. 4, and the other flow is the same as that in FIG.

  As shown in the figure, even when the shooting reservation request is in the “accepting” state (Yes in step S2), if it is not a shooting reservation from another control terminal (No in step S25), in other words, the memory When the control terminal ID registered together with the shooting state “accepting” in F3 matches the control terminal ID transmitted together with the transmitted shooting reservation, reception of the shooting reservation is permitted. At this time, the number of shots is registered by adding the current number of shots.

  Thus, when registering a shooting reservation from one control terminal CS, it is possible to make a plurality of shooting reservations in the FPD, and there is an advantage that shooting can be performed efficiently. Further, in such a situation, it is a case where a request for imaging reservation is continuously made using one control terminal CS of one operator, and a plurality of imagings for the same patient are almost always performed. In rare cases, it is expected that the imaging order of different patients will be selected. In such a case, the operator is conscious that imaging is performed continuously for a plurality of patients, so that one FPD is used. The problem of patient confusion due to overlapping registration of imaging reservations is unlikely to occur.

  FIG. 7 is a diagram illustrating a control flow of the radiation imaging system according to another embodiment. The flow shown in the figure grasps the state of the FPD connected to the communication line N in advance. First, a subroutine process (step S11) for creating an FPD state list is executed in the control terminal CS.

  FIG. 8 is a diagram showing a subroutine process for creating an FPD state list shown in step S11 of FIG. In step S111 in the figure, the reception status is inquired to all the FPDs connected to the communication line N.

  If the FPD that received the inquiry in the next step S112 is “accepting” (Yes in step S113), the FPD control unit F1 is in the “accepting” state and is in the “accepting” shooting state. The stored “control terminal ID” is returned via the communication unit F2 (step S114). On the other hand, if it is not “accepting” (No in step S113), the FPD control unit F1 replies that it is “not accepting” (step S115). In the control terminal CS, when reception of responses from all FPDs connected to the communication line N is completed (Yes in step S116), a status list of each FPD is created (step S117) and the process ends. FIG. 9 shows an example of a status list. The reception state (a2), the control terminal ID (a3) stored together with the reception state, and the like are displayed as a list together with the ID number (a1) of each FPD. The FPD ID number is a unique ID number for identification, and is assigned to each FPD in advance.

  Returning to the description of the flow of FIG. 7, following step S11, input of a photographing order or the like is performed (step S12), and then FPD selection is performed (step S13). The operation procedure for selecting the FPD will be described with reference to the operation screen.

  FIG. 10 is a detailed view of the operation screen of the operation display unit C5 in the control terminal CS. As shown in the figure, the selected photographing order information is displayed in the display column D2, and a list of selectable FPD states is displayed in the display column D1. This state list is obtained in step S11, and the example shown in the figure shows the example of FIG. 9 described above. The display column D3 displays the ID number of the control terminal that is performing the operation.

  In the figure, among the FPD lists displayed in the display column D1, the FPD in the “accepting” state does not accept imaging reservations (imaging orders) from other control terminal devices. The acceptance refusal “×” is displayed in the column D101 (D101a). In the example of the figure, the FPD 04 shown in D14 is being accepted, but the registered control terminal ID (D102) “CS02” is the control terminal ID CS02 performing the operation (column D3). Therefore, the condition “from other control terminal device” does not apply (step S25 in FIG. 6), and “O” that can be accepted is displayed in the acceptability column. The “location” column D103 of the D1 column indicates where each FPD exists, specifically, the location connected to the communication line N.

  After selecting an FPD for which a shooting reservation is to be made on the imaging device selection screen (for example, FPD03), pressing the selection execution button D4 in FIG. 8 makes a request for accepting a shooting order to the selected FPD, and the control terminal ID “CS02”. ”Is transmitted (step S14). The FPD that has received the request registers the number of shots and the control terminal ID, and sets the state to the “accepting” state (step S15). The control terminal CS that has received the information responds to the reception of the photographing reservation (step S16), and the control terminal determines the photographing reservation and the ID of the FPD (step S17) and ends.

  In the example of the embodiment, a unique control number is assigned to the control terminal ID and the FPD ID, but an IP address or a MAC address when connecting to the communication line may be used.

  In the radiation imaging system in which a plurality of consoles and a plurality of FPDs can be connected on the same communication line in this way, when the imaging reservation from one control terminal device is being accepted, By not accepting other imaging reservations, it is possible to prevent a single FPD from being registered repeatedly from a plurality of consoles, and thus to prevent a radiographic image corresponding to a patient from being mistaken, and a radiographic image A detection device can be obtained.

[Control to release "Receiving" status]
FIG. 11 is a diagram illustrating a control flow of the radiation imaging system according to another embodiment. The flow shown in the figure is to release the “accepting” state after the radiographic image capturing and the like are completed, and is subsequent to the control flow of FIGS. 4, 6, and 7.

  A radiographic image is taken on the subject (patient) 100 based on the imaging order (step S31). Imaging herein refers to irradiating the subject 100 with radiation from the irradiation device R and acquiring radiation image data in the memory F3 of the FPD based on the amount of radiation transmitted through the subject.

  Shooting is continuously performed based on the shooting reservation, and when shooting of all shooting reservations (for the number of shots) is completed (Yes in step S32), the “accepting” state of the FPD is canceled (step S33). With the cancellation, it is possible to accept registration of shooting reservations from other control terminals CS. Note that the number of shots is counted in the control unit F1, and the number of shots registered (in step S6 in FIG. 4 and the like) is reduced by the number of shots, and the remaining number of shots has become zero. Is determined to have been taken.

  The FPD transmits the captured radiographic image data to the control terminal CS of the registered control terminal ID (CS02 in the example of FIG. 10) (step S34). The control terminal CS stores the received image data in the memory C3, performs necessary image processing in the image processing unit C4, displays a radiation image on the display screen of the operation display unit (step S35), and ends. .

  FIG. 12 is a diagram showing a control flow showing a modification of FIG. The flow shown in the figure is to release the “accepting” state when transmission of image data is completed. The inside of the broken line frame B is changed with respect to the control flow of FIG. 11, and since others are common with FIG. 11, description is abbreviate | omitted.

  In step S34, when the radiographic image data is transmitted to the control terminal CS of the registered control terminal ID and transmission of all the captured radiographic image data is completed (step S345), the “accepting” state of the FPD is canceled. (Step S346) and the process ends.

  As described above, when the registered shooting reservation is completed, it is possible to accept a shooting reservation from another control terminal CS by canceling the “accepting” state of the FPD. In a radiation imaging system in which a plurality of consoles and a plurality of FPDs are connected on a line, it is possible to prevent a single FPD from being registered repeatedly from a plurality of consoles, and thus to prevent a radiographic image corresponding to a patient from being mistaken. Thus, it is possible to obtain a radiation imaging system and a radiation image detection apparatus that can perform an efficient operation that can effectively use the image.
