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 transmitted through the subject, and more particularly to a radiation imaging system connected via a communication line.

  In recent years, a digital radiographic 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 imaging 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.
JP 2006-122304 A

  Since it is possible to register a plurality of imaging orders for such an FPD, in a radiographic imaging system in which a plurality of consoles and a plurality of FPDs are connected to the same network, a plurality of unintentionally a plurality of imaging orders are registered. There are cases where the operator continuously registers imaging reservations for different patients selected by individual operators from one console to one (same) FPD. In such a case, there is a possibility that a serious problem may occur that the correspondence between the patient and the radiographic image is mistaken.

  The image processing unit C4 performs image processing such as density gain adjustment and spatial frequency conversion on the radiation image data (hereinafter also referred to as image data) acquired by the radiation image detection device F.

  The memory C3 stores the radiographic image data transmitted from the management server MS and received via the communication line N and the radiographic image data transmitted from the radiographic image detection apparatus F, and associates the radiographing order with the radiographic image data. 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.

[Management Server]
The management server MS includes a control unit M1, a communication unit M2 that functions as a reception unit, and a memory M3. The database of the memory M3 stores patient information, radiographing order information, radiographable size and memory capacity of each radiological image detection apparatus, and the like.

In addition, in the control part M1, the reception state of the radiographic image detection apparatus F is always managed.

  The “accepting” state is a point in time when the management server MS accepts an imaging reservation to be described later from the control terminal CS, and in the final period, the radiation image detection device F stores all the radiation image data related to the imaging reservation. It is the time of acquisition (information indicating that the management server MS has received) or the time when transmission of the acquired radiation image data to the control terminal CS is completed (information indicating that it has been received). The “vacant” state is a state that is not “accepting”, and at the time when all the radiographic image data related to the imaging reservation has been acquired (information indicating that it has been received) or the acquired radiographic image data is sent to the control terminal CS. From the time when transmission is completed (when information indicating that it is received) until a reservation for photographing is received from the control terminal CS. These acceptance states are stored in the memory M3. 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 M3 together with the acceptance state.

  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 a plurality of irradiation devices R1 and R2, a plurality of radiation image detection devices F1 to F4 (hereinafter referred to as FPD1 to FPD4 or FPD), and a plurality of control terminals CS1. -CS4 and management server MS are connected on 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.

  Each control terminal CS and each radiation image detection device F is assigned a control terminal ID and an FPD ID (detection device ID) as a unique ID number for identification.

  FIG. 4 is a diagram illustrating a control flow of the radiation imaging system according to the embodiment. The control flow with control terminal CS which FPD, a management server, and an operator (radiologist) operate is shown. First, the management server MS executes an FPD state list creation subroutine process (step S11).

  FIG. 5 is a diagram showing the FPD status list creation subroutine processing shown in step S11 of FIG. In step 111 in the figure, the control unit M1 of the management server inquires of all the FPDs connected to the communication line N about the registration information of the imaging reservation.

  Each FPD transmits registration information in response to the inquiry (step S112). The registration information includes a shooting reservation stored in the memory F3 and a control terminal ID that has accepted the shooting reservation.

  When the control unit M1 of the management server receives the responses from all the connected FPDs (Yes in step S113), the control unit M1 creates a status list of each FPD from the received responses (step S114) and ends.

  FIG. 6 shows an example of a list of FPD states created in step S114. FPD identification IDs (a1), acceptance states (a2), control terminal IDs (a3), etc. as detection device IDs are created as a list. The control terminal ID and the detection device ID are associated with each other and stored in the memory M3.

  Returning to the description of the control flow in FIG. In the control terminal CS, an imaging order is input by the operation display unit C5 (step S12). Note that, instead of the input by the operation display unit C5, the control unit C1 acquires the imaging orders stored in the management server MS connected to the communication line N, and the list of imaging orders displayed on the operation display unit C5 is displayed. The operator may select a required imaging order from among them.

  FIG. 7 shows an example of a plurality of imaging orders stored in the memory M3 of the management server MS. As shown in FIG. 7, 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. (P8) information on the shooting condition is included. Since patient information such as patient name (p3), sex (p4), age (p5), and the like is associated with the patient ID (p2), the patient information is also stored. 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” is for performing the imaging of front AP (irradiation from the entire surface side to the rear surface) on the chest for Mr. Ichiro Suzuki with the patient ID “100085” when the department is surgery. It shows that it is.

  In step S13, the control unit C1 of the control terminal CS inquires the management server MS about the FPD connected to the communication line N and its status list. At this time, the control terminal ID given in advance to the control terminal CS is transmitted. On the management server side, the control unit M1 adds information indicating whether or not each FPD can be accepted, and transmits FPD list information (step S14). Here, before the subroutine processing in step S14, what is the information for which acceptance is determined will be described with reference to the drawings.

  FIG. 8 is a detailed view of the display screen of the operation display unit C5 in the control terminal CS. As shown in the figure, the imaging order information input or selected in step S12 is displayed in the display field D2, and the management server MS creates the display field D1 in step S11 and determines whether or not it can be accepted in step S14. Then, the FPD status list transmitted to the control terminal CS is displayed. In the display column D3, a control terminal ID for identifying the control terminal device performing the operation is displayed.

  The symbols “◯” and “x” shown in the acceptability column D101 in the display column D1 in FIG. 8 are information that determines acceptability. Hereinafter, the control flow for making the determination will be described.

[Subroutine processing for acceptability judgment]
FIG. 9 is a diagram showing a subroutine process of step S14 shown in FIG. FIG. 9A shows an example.

  9A, the control unit M1 of the management server MS selects one FPD from among the FPDs connected to the communication line N, for example, FPD1 to FPD4. The control unit M1 refers to the state list created in step S114, and if the acceptance state of the FPD selected in step S141 (a2 in FIG. 6) is in the “accepting” state (Yes in step S142), acceptance is possible. Is set to “not acceptable” (step S144). On the other hand, if it is not in the “accepting” state, that is, if it is “vacant” (No in step S142), acceptability is set to “acceptable” (step S143). That is, the acceptability D101 in FIG. This is repeated until all the FPDs have been judged (step S145).

  As described above, when the radiological image detection apparatus F is in the accepting state in which the imaging reservation from one control terminal apparatus CS is accepted, the acceptability in the management server MS is set to the “not acceptable” state. Thus, since the management server MS manages not to accept other radiographing reservations for the radiographic image detection apparatus F, it is possible to prevent the radiographic image detection apparatus F from being registered redundantly. Can do.

  FIG. 9B is a modified example of FIG. 9A, and common processes are denoted by the same reference numerals. In the modified example of FIG. 9B, even when the state list is accepted (a2 in FIG. 6) and “being accepted” (Yes in step S142), it is registered (stored) in the memory M3 as the state list. If the control terminal ID (a3 in FIG. 6) matches the control terminal ID transmitted in step S13 (Yes in step S142b), the acceptance / rejection is set to “acceptable” (step S143). And the reception of the imaging reservation with respect to the radiographic image detection apparatus F corresponding to detection apparatus ID (ID of FPD) matched with control terminal ID is permitted.

  In this way, when making an imaging reservation from the same control terminal CS, the radiological image detection apparatus F is allowed to accept a plurality of imaging reservations. Since continuous shooting can be performed without making a next shooting reservation, there is an advantage that shooting can be performed efficiently. In such a situation, a single operator makes a series of imaging reservations using a single control terminal CS, and in most cases, performs a plurality of imagings on the same patient. 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.

  Returning to the description of the flow of FIG. In step S15, an FPD to be photographed is selected from the list. This selection method will be described based on the display screen shown in FIG.

  In FIG. 8, among FPD lists displayed in the display column D1, FPDs whose status column D17 is “accepting” are configured not to accept imaging orders from other control terminal devices. “X” indicating that reception is not possible is displayed in D101 (D101a). In the example shown in FIG. 9B, according to the control flow shown in FIG. 9B, the FPD 04 shown in D14 has the status column D17 “Accepting”, but the control terminal ID (D102) registered together with the shooting reservation is shown. Since “CS02” coincides with CS02 (D3 column) of the control terminal ID that is performing the operation, the condition from another control terminal device does not apply (step S142b in FIG. 9). For this reason, “◯” indicating acceptability is displayed in the acceptability column D101 (D101b). The “location” column D103 of the D1 column indicates where each FPD exists, specifically, the location connected to the communication line N.

  In step S15, selection of the FPD is completed by selecting the FPD to be photographed from the list of acceptable FPDs (FPD03 in the example of FIG. 6) and pressing the selection execution button D4. The control unit C1 of the control terminal CS transmits the imaging reservation and the imaging order related to the imaging reservation to the management server MS together with the control terminal ID (step S16). The management server MS registers the FPD ID, control terminal ID, shooting reservation, and shooting order transmitted in step S16, and sets the state of the corresponding FPD (for example, FPD03) to the “accepting” state (step S17). .

  The control unit M1 of the management server MS transmits to the corresponding FPD (for example, FPD03) the control terminal ID, the shooting reservation, the shooting order, and the fact that the shooting reservation has been registered as information related to shooting received in step S17 ( In step S18), the received FPD registers the information in the memory F3 (step S20) and ends.

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

  Thus, in the radiation imaging system in which the management server MS, the plurality of control terminals CS, and the plurality of FPDs can be connected on the same communication line, the FPD accepts an imaging reservation from one control terminal device. ”State, the management server MS manages so as not to accept other shooting reservations for the FPD, thereby preventing one FPD from being reserved for shooting from a plurality of consoles. As a result, it is possible to obtain a radiation system that prevents the radiation image corresponding to the patient from being mistaken.

[Control to release "Receiving" status]
FIG. 10 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 a continuation of the control flow of FIG. 4.

  First, in step S31, the FPD captures a radiographic image on the subject (patient) 100 based on the imaging order registered in step S20. 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.

  The FPD continuously performs shooting if there are a plurality of shooting orders. When shooting for all the shooting orders is completed (Yes in step S32), a signal indicating the completion of shooting order is managed together with the ID of the FPD. It transmits to the server MS (step S33). The management server MS that has received the imaging order completion cancels the “accepting” state of the FPD (for example, FPD03) corresponding to the FPD ID transmitted in step S33 in the state list created in step S11 (step S34). ). By releasing the “accepting” state, the FPD 03 can subsequently accept registration of shooting reservations from other control terminals CS.

  In the FPD, the captured radiographic image data is transmitted to the control terminal CS to which the control terminal ID registered in step S20 is given together with the ID of its own FPD (step S35). In the control terminal CS, the radiation image data transmitted in step S35 is stored in the memory C3, the image processing unit C4 performs necessary image processing, and then the radiation image is displayed on the display screen of the operation display unit C5 (step S36) and the process ends.

  FIG. 11 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 is changed with respect to the control flow of FIG. 10, and the others are common to FIG.

  The FPD transmits the radiation image data to the control terminal CS to which the control terminal ID registered in step S20 (FIG. 4) is assigned, and when reception of all the radiation image data is completed in the control terminal CS (in step S41) Yes) The fact that the reception of the image data related to the registered photographing order has been completed is transmitted to the management server MS together with the FPD ID received in step S35 (step S42). Accordingly, the management server MS cancels the “accepting” state of the FPD corresponding to the FPD ID transmitted in step S42 (step S43). Further, the FPD is instructed to cancel the shooting reservation (step S44).

  Further, the FPD receives the imaging reservation cancel command transmitted in step S44, deletes the imaging reservation, imaging order, and radiation image data registered in the memory F3 (step S45) and ends.

  As described above, when the registered imaging order is completed, it is possible to receive imaging orders from other control terminals CS by releasing the “accepting” state of the FPD. In a radiography system in which a plurality of consoles and a plurality of FPDs are connected on a communication line, it is possible to prevent one FPD from being registered repeatedly from a plurality of consoles and, in turn, to prevent mistakes in radiation images corresponding to patients. Therefore, it is possible to obtain a radiation system that enables efficient operation that can effectively use the FPD.
