Description

  The present invention relates to a radiographic image capturing system that captures a radiographic image using an FPD.

  In recent years, an imaging apparatus using an FPD (Flat Panel Detector) has been used together with CR (Computed Radiography) that acquires a radiographic image widely used as a medical image as digital image data. Since the FPD can directly convert a radiographic image into a CR, it has an advantage that the success or failure of imaging can be immediately determined by temporarily confirming the image at the imaging site (for example, patents). Reference 1).

In addition, the FPD has a communication function, a system for managing information in a hospital (hereinafter referred to as HIS; Hospital Information System), a system for managing information in a radiology department (hereinafter referred to as RIS; Radiology Information System), and the like. It is possible to transmit to an information management apparatus such as a server which is connected via a communication network such as a LAN (Local Area Network) and manages the acquired radiographic image information. Therefore, after imaging the patient as a subject, an image is confirmed by an engineer at the imaging site, and if the imaging is successful, the radiographic image is transmitted to the information management apparatus via the network and stored, so that the FPD It is possible to perform continuous imaging by erasing the radiographic image recorded in (1).
The FPD is provided with a console connected via a predetermined communication line. The console performs predetermined image processing on the radiographic image acquired by the FPD and displays the radiographic image or transmits it to the information management apparatus. The radiation image to be performed is associated with the imaging order information.

  In addition, a cassette type FPD in which the FPD is accommodated in a cassette and the transportability and handleability of the FPD is improved has been developed (see Patent Document 2).

  In such a radiographic image capturing system using FPD, there is known a system configured to display a radiographic image on a console such as a PC (Personal Computer) when temporarily confirming an image at a photographing site. (See Patent Document 3). For example, in Patent Document 1, an FPD and a console are connected via a system-dedicated communication line, and radiographic image information is transmitted from the FPD to the console, and a thumbnail image created based on the radiographic image received by the console By displaying a reduced image such as the above on the console, it is possible to check the shooting state.

In addition, conventionally, FPDs and consoles are normally used in a one-to-one correspondence with each other. Usually, a console is provided in front of a radiographic imaging room, and an FPD provided in the radiographic imaging room is used. Image processing is performed. However, with the recent development of communication networks, there are cases where a plurality of FPDs are connected and used for one console for various reasons such as space.
For example, it is a case where imaging is performed using an FPD in a radiographic imaging room where a plurality of images are taken for one subject.

  When an FPD connected on the same network and a plurality of consoles are used in combination, the images obtained from the respective FPDs are the consoles in front of the radiation imaging room that directly manages the FPDs. Therefore, the radiographic images captured by the FPDs in the different radiographing rooms are sent to separate consoles in front of the radiographic image radiographing rooms in which the respective FPDs are arranged. For this reason, when confirming the photographing, the photographing engineer has to reciprocate to confirm the photographing state to a remote console, which is extremely inconvenient.

It is determined whether or not it is acceptable (step S16).
Specifically, the control unit 11 determines that the radiographic image information may be transmitted when a signal including information that the radiographic image capturing state is appropriate is input as the radiography appropriateness signal. When a signal including information indicating that the radiographic image capturing state is inappropriate is input as the radiographing propriety signal, it is determined that there is no need to transmit the radiographic image information.
If it is determined that the radiation image information may be transmitted to the console 30a (step S16; Yes), the control unit 11 acquires the radiation image information from the image memory 15 and acquires the acquired radiation image. Information is transmitted from the communication unit 16 to the console 30a (step S17).

In the console 30a, when the radiation image information transmitted from the communication unit 16 of the FPD 10 is received via the communication unit 36, the control unit 31 of the console 30a performs radiation related to the radiation image information based on the received radiation image information. Predetermined image processing such as image gradation processing and γ conversion processing is performed (step S18).
Thereafter, the control unit 31 stores the radiographic image information after the image processing in a predetermined area of the image storage unit 35 (step S19).

When it is determined in step S16 that the radiographic image information does not need to be transmitted to the console 30a (step S16; NO), the control unit 11 controls each unit of the FPD 10 to control the radiographic image. Shifts to the re-photographing acceptance state (step S20).
Here, the control unit 11 may be configured to delete the radiation image information that does not need to be transmitted to the console 30a.

As described above, according to the radiographic image capturing system 100 of the first embodiment, a plurality of consoles 30a and 30b are connected to one FPD 10 on the same network N and used for capturing information and capturing before capturing. The FPD 10 to be registered is registered with the console 30a, and the reduced image information generated based on the radiation image information generated with the FPD 10 is output to the console 30a that has registered the FPD 10 used for imaging, and the reduced image is displayed. Therefore, even when a plurality of consoles 30a and 30b are connected to the same network for one FPD 10 and the radiographing is performed, it is possible to check the radiographing state. Can be quickly performed on the console 30a that has registered the shooting information and the FPD 10 used for shooting. Thereby improving the efficiency. In addition, image confirmation can be performed accurately, and the rate at which medical errors occur can be reduced.
Further, since the reduced image information having a smaller amount of information than the radiation image information is output to the console 30a, the transfer time of the display image information can be shortened, and the radiation image can be quickly displayed on the console 30a after the radiation imaging. Can be done.

  In the present embodiment, the FPD 10 is connected to the network N via a cable or the like. However, a base station for performing wireless communication such as a wireless LAN is provided, and the FPD 10 is connected to the network N via the base station. It may be a wireless communication system to be connected to.
