Description

  The present invention relates to an image generation system that images a patient and generates a medical image.

  In recent years, digitalization of medical images obtained by examination imaging and the like has been realized, and when digital image data is obtained by an imaging device such as a computer radiographic imaging device (hereinafter referred to as a CR (Computed Radiography) device), a communication network An image generation system that distributes to various devices via the Internet is used.

Such an image generation system includes, for example, a plurality of imaging apparatuses that capture a medical image of a patient using a portable cassette that contains a phosphor plate on which a stimulable phosphor layer is formed and that transmits radiation transmitted through a subject. A plurality of reading devices for reading medical images recorded in the cassette, a plurality of control devices for managing the medical images generated by these imaging devices and reading devices, a radiology information system RIS (Radiology Information System) and a hospital A so-called distributed processing system in which an information system HIS (Hospital Information System) is connected via a network is disclosed (see Patent Document 1).
This system allows multiple technicians to simultaneously perform multiple radiographs (multiple radiographs corresponding to the patient and / or multiple sites (including directions)), and is used in relatively large radiology departments. There are many cases.

As an example of an engineer's workflow in the above distributed processing system, first, imaging order information (instruction information for instructing a patient to be imaged, an imaging region, an imaging method, etc.) at a request from a doctor in advance in HIS / RIS before imaging. Is issued and transmitted to the control device. Then, when the imaging order information is displayed on the plurality of control devices, the engineer selects the imaging order information that he / she performs imaging from among the displayed imaging order information, and the imaging order information is displayed. A cassette registration process (pre-registration process) for associating information with cassette ID information to be used for imaging is performed. Generally, a plurality of imaging operations can be performed at a time like the front and side of chest imaging. Therefore, it is usual to perform a plurality of cassette registration processes.
After the cassette registration process, the technician moves to the imaging room together with the cassette, takes a picture of the patient, returns to the control device that performed the cassette registration process, and waits for the image to be transmitted.

When processing is performed by a mammography apparatus under the above distributed processing system, the mammogram is read in a high-definition mode (reading with a smaller pixel than in general imaging), so that the amount of data flying over the network increases. In particular, when a phase contrast mammography apparatus is used, the amount of data increases. Therefore, when mammography is used so as not to cause network busy of the entire distributed processing system, a plurality of control apparatuses and a plurality of reading apparatuses are used. Among these, the distributed processing in which an arbitrary reader can be connected to an arbitrary controller for general radiography after changing the network configuration to be used in a combination of a specific controller and a specific reader and completing mammography A system that can be switched to a system is disclosed (see Patent Document 2).

When a breast image is captured, it is common to perform four images of a vertical breast, a vertical breast, a vertical breast, an oblique left breast, and a diagonal right breast for a single patient. In this case, it is assumed that all four cassettes will be registered before shooting, but if a cassette is dropped during use, a cassette that is different from the cassette registered in the actual shooting order information will be used for shooting. In other words, the site may be mistaken. In the case of a breast image, it is impossible to discriminate between the left and right breast images simply by looking at the image, and there is a risk that a normal breast may be operated without noticing the wrong part.
If careful attention is paid so that there is no risk of this confusion, it is possible to execute a plurality of cassette registration processes in a batch. (It can be easily imagined that misuse is unlikely to occur if the cassette size used is different.)
When an engineer performs photography alone, the engineer performs one or more cassette registration processes with a control device installed in the front room of the imaging room, etc., and an imaging room in which an X-ray source and a mammography apparatus are installed Move to (usually a room shielded with lead or the like), finish positioning, and irradiate X-rays. When all the photographing is completed or each photographing is finished, the photographing room is moved to the reading device, and image reading is started from the photographed cassette.
Furthermore, in the case of an engineer who wants to completely prevent mistakes, it is assumed that the cassette registration process itself is performed every time shooting is performed.

On the other hand, the necessary work as described above is divided into indoor work centered on patient positioning and outdoor work such as cassette registration processing / image confirmation processing, etc., and the former is a specific engineer (for example, female engineer). In the latter case, it is assumed that the efficiency of the entire photographing will be improved by the division of labor supported by general engineers accustomed to the distributed processing for general photographing.
In this case, the latter engineer (hereinafter referred to as a support engineer) selects one piece of imaging order information (for example, the left breast in the vertical direction) from the plurality of pieces of imaging order information of one subject, and first handles one cassette. Attach (cassette registration process) and give the registered cassette to a specific engineer. The specific engineer performs imaging corresponding to the imaging order information (vertical left breast) using the received cassette. In this case, since the support engineer is accustomed to cassette registration for a plurality of pieces of imaging order information, the next imaging order information (for example, the vertical breast in the vertical direction) is selected, and the cassette registration process is executed and waits.

  In this case, information processing can be performed in cooperation between the imaging device and the control device. For example, a processing method in which the imaging device transmits an imaging execution result to the control device, and the control device associates the imaging execution result with imaging order information can be considered. The imaging device transmits imaging execution information (vertical left breast) to the control device, and the control device associates the imaging execution result (vertical left breast) with imaging order information of the vertical left breast. When the support engineer selects the next radiographing order information (vertical right breast) and performs cassette registration processing, it is sent from the radiographing device during this time, and the radiography result (originally the vertical breast in the vertical direction) is This is not preferable because it is associated with the imaging order information (right breast in the vertical direction) and may cause the right and left breasts to be mixed.

  In view of the above problems, the problem of the present invention is that the imaging apparatus and the control apparatus cooperate with each other, so that the control apparatus does not accept a plurality of imaging order information selections, and the overall imaging flow efficiency (work flow line shortening). ) In the control apparatus for selecting a plurality of radiographing order information can be selected as appropriate, and an appropriate mode can be selected as appropriate according to the imaging mode (general radiography or mammography). It is to increase efficiency and to prevent site confusion.

  According to the first aspect of the present invention, at least one control device that stores imaging order information in association with identification information of a cassette used for imaging, and at least one imaging that captures a medical image of a patient using the cassette. In the image generation system in which the apparatus is connected via a network, the imaging apparatus includes imaging execution information generation means for generating imaging execution information related to the imaging every time the medical image is captured, and the imaging execution Transmitting means for transmitting the imaging execution information generated by the information generating means to the control device, the control device storing storage means for storing the imaging order information, and the cassette used for imaging the medical image. Identification information acquisition means for acquiring the identification information set in advance, the imaging order information stored in the storage means, Registration means for associating and storing the identification information acquired by the separate information acquisition means in the storage means, receiving means for receiving the imaging execution information transmitted from the imaging device, and the imaging by the registration means After the order information and the identification information are stored in association with each other, the imaging execution information generated and transmitted from the imaging apparatus when the medical image is captured using the cassette corresponding to the identification information is stored in the imaging execution information. In accordance with the instruction selected by the selection unit, the selection unit accepts an instruction as to whether or not the registration unit associates the imaging order information with the identification information until it is received by the reception unit. Control means for controlling association between the imaging order information and the identification information by a registration means.

  According to a second aspect of the present invention, in the image generation system according to the first aspect, the imaging device is a radiographic image capturing device that captures a breast image as the medical image.

  According to a third aspect of the present invention, in the image generation system according to the second aspect, the imaging execution information includes an exposure completion signal indicating completion of radiation exposure to the patient.

  According to the first aspect of the present invention, after the imaging order information and the cassette identification information are stored in association with each other, the medical image is captured using the cassette corresponding to the cassette identification information. Since it is possible to prohibit the association between the photographing order information and the cassette identification information until the photographing execution information generated and transmitted from the photographing device is received, it is possible to prevent mistakes in the cassette, and the photographing device and the control device A mode that does not accept selection of a plurality of imaging order information in the control device for the cooperation of the control device, and a mode that allows selection of a plurality of imaging order information in the control device for streamlining the entire imaging (work flow line shortening) Both can be selected as appropriate, the appropriate mode can be selected as appropriate according to the imaging mode, and the overall radiology department efficiency can be improved, and the mistake of the part can be prevented. Rukoto can.

  According to the second aspect of the present invention, the same effects as those of the first aspect can be obtained, and two imaging technicians, the person in charge of the photographing apparatus and the person in charge of the control apparatus, can be used to treat one patient. When taking a breast image that captures multiple parts, if the right and left breast images are difficult to discern the difference in cassettes from the captured image, you will not notice the difference in cassettes if you make a mistake in the order of imaging and the order in which cassettes are used. In addition, it is possible to prevent the possibility of performing a procedure such as surgery for mistaking a part, and it is possible to prevent a decrease in reliability of the image generation system.

  According to the third aspect of the present invention, the same effect as that of the second aspect can be obtained, and until the exposure completion signal indicating the completion of the radiation exposure is received from the patient, that is, with certainty. Until imaging of the breast image is completed, the association between the other imaging order information and the identification information of the other cassette can be prohibited, and the other imaging order information and the identification information of the other cassette are erroneously set before the imaging. Can be prevented from being associated with each other, and a part confusion can be prevented in advance.

  In the cassette registration process, when imaging order information is selected via the input unit 34 and a cassette ID of a cassette used for imaging a breast image is input according to the imaging order information, the imaging order information and the cassette ID are obtained. This is a process of associating and storing in the order file 32a of the storage unit 32.

  The one-person mode is generated when a breast image is captured using the cassette corresponding to the cassette ID after being stored in the order file 32a in association with the imaging order information and the cassette ID, and transmitted from the imaging apparatus 10. In this mode, the cassette registration process is allowed regardless of whether or not the shooting execution information is received by the communication unit 36.

  The two-person mode is generated when the breast image is captured using the cassette corresponding to the cassette ID after the imaging order information and the cassette ID are associated with each other and stored in the order file 32a.

Receive the cassette ID.

Next, the operation of the present embodiment will be described.
FIG. 4 shows a flowchart of pre-registration processing in the present embodiment.

  First, in the control device 30, the mode is accepted when the imaging engineer inputs a selection instruction for the single mode or the dual mode via the input unit 34 (step S1). Based on the imaging order information stored in the order file 32a, a list of patients scheduled for imaging is displayed on the display unit 35. When the imaging engineer selects and inputs a patient to be imaged via the input unit 34 among the patients displayed in the list, the imaging order information corresponding to the selected patient is displayed in a list on the display unit 35 (step S2).

  The imaging engineer inputs an instruction to select imaging order information to be associated with the cassette from the imaging order information displayed in the list through the input unit 34, and the imaging order information is selected (step S3). In addition, the selected imaging order information is added to the selected imaging order information. Accordingly, the imaging engineer inputs the cassette ID of the cassette used for imaging the patient via the input unit 34, and the cassette ID is acquired (step S4).

  The control device 30 stores the selected imaging order information and the acquired cassette ID in association with each other in the order file 32a (step S5). The imaging order information associated with the cassette ID is transmitted via the communication unit 36 (step S6).

  Then, the cassette associated with the photographing order information is transported to the photographing room in which the photographing device 10 is installed and mounted on the photographing stand of the photographing unit 17 of the photographing device 10. The imaging order information associated with the cassette is displayed on the display unit 14 of the imaging apparatus 10 (step S7).

  In the imaging apparatus 10, the imaging engineer puts the patient as the subject at the imaging position according to the imaging order information, adjusts the imaging region and imaging direction of the imaging target, and then inputs an imaging instruction via the input unit 13. The imaging apparatus 10 performs imaging processing by irradiating radiation according to the input imaging instruction (step S8).

  After imaging, the imaging device 10 generates imaging execution information including an exposure completion signal, and transmits the generated imaging execution information to the control device 30 (step S9).

  On the other hand, after transmitting the imaging order information to the imaging device 10 (after step S6), the control device 30 determines whether or not an instruction to end the cassette pre-registration process has been input via the input unit 34 (step S10). ).

  If the control device 30 determines that an instruction to end the cassette pre-registration process is not input via the input unit 34 (step S10; No), is the mode input in step S1 a mode for two people? It is determined whether or not (step S11).

  When determining that the mode is not the two-person mode (step S11; No), the control device 30 returns to step S1, and when determining that the mode is the two-person mode (step S11; Yes), in step S5 It is determined whether or not an exposure completion signal included in the imaging execution information generated when the breast image is acquired according to the associated imaging order information (step S12).

  When it is determined that the exposure completion signal included in the imaging execution information has not been received (step S12; No), the control device 30 waits until the exposure completion signal is received, and the exposure included in the imaging execution information. When it is determined that the completion signal has been received (step S12; Yes), the process returns to step S1, and the imaging order information and the cassette ID are continuously associated with each other.

  When it is determined that the instruction to end the cassette pre-registration process has been input via the input unit 34 (step S10; Yes), the control device 30 ends the present process.

  As described above, according to the present embodiment, the imaging order information and the cassette ID are stored in association with each other, and then generated when a breast image is captured using the cassette corresponding to the cassette ID. Until the photographing execution information transmitted from the photographing apparatus 10 is received, the association between the photographing order information and the cassette ID can be prohibited. Therefore, only one cassette is used, and the cassette usage order is mistaken. Nothing will happen. Therefore, because of the cooperation between the imaging device and the control device, the control device does not accept a plurality of imaging order information selections, and the control device for the flow efficiency of the entire imaging (work flow line shortening). Both modes that allow selection of radiographing order information can be selected as appropriate, and an appropriate mode can be selected according to the radiographing mode (general radiography or mammography), improving the overall radiology efficiency and preventing misplacement of parts. can do.

  In particular, when two imaging technicians, an imaging engineer in charge of the imaging device 10 and an imaging engineer in charge of the control device 30, cooperate to perform imaging of a breast image in which a plurality of parts are imaged for a single patient, It is difficult to distinguish between cassettes from the captured images. If the imaging order and cassette usage order are incorrect in the left and right breast images, you will not be aware of the cassette mistakes and prevent the possibility of surgical procedures such as part mistakes. This can prevent a decrease in the reliability of the image generation system.

  Further, the present invention is not limited to the contents of the above embodiment, and can be appropriately changed without departing from the gist of the present invention.
