Description

  The present invention relates to management of radiological medical images, and relates to, for example, a technique for improving work records of a radiographer and cooperation of medical images between a radiographer and a report generating doctor.

  2. Description of the Related Art In recent years, a medical image diagnostic apparatus that collects information inside a human body and generates and displays a medical image representing a state of a structure or function inside the human body based on the collected information is used. As this medical image diagnostic apparatus, an X-ray diagnostic apparatus, an X-ray CT diagnostic apparatus, an MRI apparatus (nuclear magnetic resonance image diagnostic apparatus), an ultrasonic image diagnostic apparatus, a nuclear medicine diagnostic apparatus, and the like are known. Such a medical imaging apparatus such as a CT diagnostic apparatus or an MRI apparatus is called a modality. In addition, there is a medical image management system (PACS) that stores the medical images collected by the medical image diagnostic apparatus, and the PACS includes an image server that stores the medical images. Further, there are known medical information systems such as an interpretation terminal which is a report creation terminal for inputting medical findings and the like for the medical image, and a medical report apparatus (report server) for storing the input information. In addition, a RIS (Radiology Information System) that digitizes and manages information such as medical images (radiograms) and examination information handled in the radiology, a server that performs control and data management of this RIS. A RIS terminal is known as a certain RIS server and an engineer terminal which is a terminal for confirming information recorded in the RIS server and inputting information.

  In general, a medical image taken by a radiologist with a medical imaging apparatus is stored by the radiologist from the medical imaging apparatus to the PACS image server (see, for example, Patent Document 1). Further, the examination end information for notifying that the medical practice by the medical imaging apparatus has been completed is input from the technician terminal to the RIS server by the radiographer (see, for example, Patent Document 2). .) Furthermore, the RIS server receives and stores patient information and examination information input by a medical doctor from an HIS (Hospital Information System) server that integrates and manages information for the entire hospital. Then, the order information indicating the inspection request and the inspection end information are periodically read from the report server to the RIS server, and the report server stores the information (see, for example, Patent Document 3). ).

The report creating doctor performs image diagnosis by referring to a medical image in the image server using a medical image viewer on the report creating terminal, and reports information as a result of image diagnosis for the medical image is used for medical use on the report creating terminal. Create by report creation means. Then, the doctors of each clinical department who requested these examinations display the report information on the terminal of the clinical department and perform medical care.

  In this type of conventional system, it is necessary for the technician who took the image to deliver the image to the image server by himself using a medical imaging device, and the engineer himself uses the engineer terminal separately from the delivery Therefore, it is necessary to input inspection end information to the RIS server. The delivery to the image server and the input of the inspection end information to the RIS server have not been performed in any way. For this reason, the radiologist inputs the examination end information to the RIS, but if the delivery of the photographed image to the image server is delayed, the examination end information is input to the RIS. In other words, there may be a situation in which there is no captured image in the image server. In this case, there was a situation in which the medical image necessary for interpretation could not be referred to even if the report creation doctor confirmed that the examination was performed with reference to the examination end information and tried to create the interpretation report. .

  In this regard, a method of making it impossible to input examination end information to the RIS server unless the delivery of the medical image to the image server is completed is also conceivable. However, the inspection end information is not only used for interpretation, but also used for checking the end of the inspection for accounting, etc. Therefore, the input of the inspection end information itself needs to be performed quickly. On the other hand, delivery of medical images requires time because a radiologist selects and sends necessary images later. Therefore, it is usually necessary to input the examination end information to the RIS server before the completion of delivery of the medical image, and the above-described method is not practical.

  In addition, since there is no cooperation between the RIS server and image delivery to the image server, the management of the image delivery time, operator, number of images, and delivery destination is not performed by the RIS server, and information such as the delivery status of the image is confirmed. In order to do this, it was possible only at a specific location such as a medical image capturing apparatus actually delivered or a delivered image server.

  Furthermore, in the conventional method, registration notification information and inspection information are read from the report server to the RIS server, so even if the RIS server confirms completion of image delivery, the information is not immediately reflected in the report server. A time lag occurs until the report server is read.

  The present invention has been made in view of such circumstances, and aims to link the registration information of the RIS server and the image server, to link the RIS server and the report server, and further to determine the image delivery status in the RIS server. By performing management, it is ensured that medical images necessary for image interpretation exist in the image server, and the load of movement for checking the delivery status is reduced, and the responsibility for image delivery is managed. It is an object.

  In order to achieve the above object, a medical image management system according to claim 1, a medical image photographing apparatus for photographing a medical image, an image server for storing the medical image, order information indicating an examination request, and completion of photographing A medical image management system comprising: an RIS server that manages examination end information representing the information; an engineer terminal that confirms and inputs information of the RIS server; and a report server that creates an image diagnosis report for the image, The engineer terminal includes image number input means for inputting, to the RIS server, the number of images of the medical image to be delivered to the image server, and the RIS server stores information on the input number of images. A number storage unit for accessing the image server to confirm the number of delivered medical images, and storing the stored number of images and the Comparing the number of images to be sent, and when the delivery is completed, the delivery server has an image quantity confirmation means for providing the examination completion information and the order information in response to the examination completion confirmation request from the report server. It is characterized by having an error display means for displaying an error when is not completed.

  The medical image management method according to claim 5, wherein the RIS server receives information about the number of images sent from the medical image photographing apparatus to the image server from the RIS terminal and stores the number of images, and the RIS server includes the image server. The number of delivery images delivered to is periodically checked, and compared with the stored information on the number of images, if the number of delivery images matches the number of stored images, the delivery completion information is stored and the match If not, an error message is displayed. If the number of delivered images is less than the stored number of images, the confirmation is repeated. If the number of delivered images is greater than the stored number of images, the confirmation is completed. Periodically confirming the delivery completion information of the RIS server, and when the report server receives a report creation request from the report creation terminal, the delivery completion information from the RIS server. If it has received the order information indicating the inspection request and the inspection end information indicating the completion of imaging, the medical image is called from the image server, and if the delivery completion information has not been received, the report creation request is rejected. And a step of performing.

  According to the first and fifth aspects of the present invention, a radiographer who has taken a medical image using a medical image photographing apparatus inputs the number of images to be delivered to the image server to the RIS server, and based on the information. After the RIS server confirms that the same number of medical images as the information actually exists in the image server, the test end information in the report server No wrinkles occur during the completion of delivery of the medical image to the image server. Therefore, the necessary medical image is always present in the image server when the report preparing doctor confirms the examination end information of the report server and tries to perform interpretation. Thereby, forgetting delivery of the medical image can be prevented, and there is a specific effect that it is ensured that the medical image necessary for interpretation is surely present in the image server.

  An example of an embodiment of a medical image management system according to the present invention will be described in detail with reference to the drawings.

[First Embodiment]
FIG. 1 is a block diagram showing a configuration of the entire system of the present invention, and FIG. 2 is a flowchart of data among RIS server, image server, and report server.

  As shown in FIG. 1, the overall system configuration includes an RIS server 1, an image server 2, a report server 3, a medical imaging apparatus 4, an engineer terminal 5, a report creation terminal 6, and an HIS server 7 on the network. Has been. The CPU of the RIS server 1 controls the image number storage means 11, the image number confirmation means 12, the inspection information storage means 13, and the error display means 14. The CPU of the image server 2 controls the image storage means 21 and the report server. 3, the control of the examination end information confirmation means 31, the information display means 32, and the interpretation information storage means 33 is controlled, the CPU of the medical image photographing apparatus 4 controls the image transmission means 41, and the CPU of the technician terminal 5 inputs the number of images. The CPU of the report creation terminal 6 controls the information calling means 61, the interpretation information input means 62, and the information confirmation means 63, respectively.

  The function of the system having such a configuration will be described with reference to FIG. First, the order information sent from the HIS server 7 is stored in the inspection information storage means 13. An examination is performed by a radiographer (hereinafter referred to as “engineer”) that captures a medical image based on the order information, and a medical image is captured by the medical image capturing apparatus 4. When the inspection is completed, the engineer who performed the inspection uses the inspection end information input means 52 of the engineer terminal 5 to input the inspection end information. This inspection end information is stored in the inspection information storage means 13 of the RIS server 1. The engineer who has performed the examination selects a necessary image to be sent to the image server 2 from the taken medical images, and inputs the number from the image number input means 51. This image number information is stored in the image number storage means 11 of the RIS server 1. Next, the engineer sends the selected medical image to the image server 2 using the image transmission unit 41 of the medical image photographing device 4, and this image is stored in the image storage unit 21 of the image server 2. Here, both the medical image photographing device 4 and the engineer terminal 5 are in the hands of the engineer, and are arranged at a location away from the server room where the server such as the RIS server 1 is installed. However, since the medical imaging device 4 and the engineer terminal 5 do not exchange information about images with each other, a separate operation for the number of images is required as described above.

  Next, the flow of confirming the number of images by the RIS server 1 will be described using the flowchart of FIG. First, when the number of images is input to the RIS server 1 in step S1, the number of delivered images stored in the image server 2 in step S7 is periodically checked by the image number confirmation means 12 in step S2. Go to go. Here, the number of images stored in the image number storage means 11 in step S3 is compared with the number of images stored in the image server 2. If the number of images is the same, the inspection information storage means 13 is stored in step S4. The delivery completion is memorized. If the number of images is not the same in step S3, an error is displayed in step S5. If the number of medical images in the image server 2 is small in step S6, periodic confirmation is repeated. In step S6, the image server is repeated. When the number of medical images in 2 is large, the confirmation operation is terminated.

  At this time, in step S5, it is possible to confirm how many images have been sent to the image server 2 at the current time by the image number confirmation means 12 in step S1, and in step S2, what is the final required number of images. Since the number of images is stored in the number-of-images storage means 11, the delivery status such as how much delivery has been completed can be sent to the technician terminal 5 by comparing them.

  Next, the flow of interpretation by the report server 3 will be described using the flowchart of FIG. First, the report server 3 periodically checks the examination end information held by the examination information storage unit 13 of the RIS server 1 by the examination end information confirmation unit 31. At this time, if there is delivery completion information in the examination information storage means 13, the RIS server 1 responds to a request from the examination end information confirmation means 31 and provides examination end information and order information. If there is no delivery completion information, the inspection end information confirmation unit 31 repeats periodic confirmation without responding to the request from the inspection end information confirmation unit 31. In step S8, the report creating doctor uses the information confirming means 63 of the report creating terminal 6 to request the report server 3 to create a report, and in step S9, the test end information confirming means 31 refers to whether the test end information is included. If the inspection end information is in the inspection end information confirmation means 31, the interpretation is started. If there is no inspection end information in step S9, the creation of the report is rejected. The report creating doctor requests the order information from the report server 3 by the information calling means 61 and receives the order information by the information display means 32, and interprets the interpretation by referring to the medical image existing in the image server 2 in step S10. In step S11, the result of interpretation is input by the interpretation information input unit 62, and the information is stored in the interpretation information storage unit of the report server 3 in association with the corresponding order information or medical image.

  In this way, when the report creator confirms the examination end information and starts reading, it is guaranteed that the image corresponding to the report creation is always stored in the image server, and there is no necessary medical image. The stagnation of interpretation due to is resolved.

[Second Embodiment]
A second embodiment according to the present invention will be described. In this embodiment, when the number of images is input from the image number input means 51 of the engineer terminal 5 in the medical image system of the first embodiment, the time of input using the system clock or the login name to the system is used. The input person is automatically stored in the RIS server 1. Further, the engineer terminal 5 of the present embodiment is provided with means for inputting the delivery destination of the medical image, and is configured so that the delivery destination of the medical image can be stored in the RIS server 1.

  As a result, the person who sent the image from anywhere, the number of deliveries and the number of deliveries can be obtained as long as the engineer terminal 5 is available, without going to the medical image capturing apparatus 4 that bothered to send the image or the image server 2 in the remote server room. Since the input time and the image server 2 of the delivery destination can be confirmed, it is easy to confirm the delivery status of the medical image, and the management of the delivery of the medical image is prevented and the management of the responsibility for the image delivery is also ensured. It will surely be possible. In addition, because the image storage location is easily known, system maintainability is also improved.

  Furthermore, in the present embodiment, the delivery status from the engineer terminal 5 is confirmed in consideration of safety, but it is also possible to configure so that the delivery status can be confirmed from a browser using HTTP or the like. By doing so, it becomes possible to confirm the delivery status from a general computer.

[Third Embodiment]
In the medical image management system according to the third embodiment of the present invention, in the first embodiment, the RIS server 1 has an examination end notification unit, and the examination end information confirmation unit 31 of the report server 3 periodically performs an RIS. The server 1 is configured not to check the inspection end information.

  The flow of the inspection end notification by the RIS server 1 at this time will be described using the flowchart of FIG. First, similarly to the flow of the first embodiment, in step S3, the RIS server 1 compares the number of medical images existing in the image server 2 with the number stored in the image number storage unit 11. Next, when the number of medical images in the image server 2 matches the number stored in step S3, the test server 3 notifies the report server 3 of the test end by the test end notification means of the RIS server 1 in step S4. Thereby, the report server 3 has inspection end information. When the examination end information is confirmed and interpretation is performed in step S9, the order information requested by the information display means 32 of the report server 3 is provided, and in step S10, the medical image in the examination in the image server is called.

  Accordingly, in step S4, since the RIS server 1 confirms the completion of the delivery of the image to the image server 2, and simultaneously notifies the report server 3 of the inspection end information, the RIS server confirms the completion of the delivery. The inspection end information of the RIS server 1 is not reflected on the report server 3 until the timing of periodic inspection end information confirmation, and the time lag between the completion of image delivery and the information update of the report server 3 is eliminated. As a result, quicker interpretation is possible.

[Fourth Embodiment]
The medical image system according to the fourth embodiment of the present invention uses the communication means such as MPPS to input the number of images to the RIS server 1 performed by the engineer in the first embodiment. In this configuration, the number of images is directly notified from the imaging device 4 to the RIS server 1 via the engineer terminal 5.

  In the present embodiment, the engineer who has performed the inspection transmits the necessary medical image to the image server 2 by the image transmission unit 41 of the medical image capturing apparatus 4, and at the same time, using the communication unit between the engineer terminal 5 and the medical image capturing apparatus 4. The number of transmissions to the image server 2 is notified to the RIS server 1 via the engineer terminal 5. This number information is stored in the information storage means 13 of the RIS server 1 and used for comparison with the number of medical images existing in the image server 2.

  This eliminates the need for the technician to separately deliver the medical image to the image server 2 and input the number of images to be delivered to the RIS server 1. If the medical image is delivered from the medical imaging apparatus 4 to the image server 2, The number of sheets is automatically notified to the RIS server 1. As a result, the number of medical images delivered from the medical image photographing device 4 to the image server 2 and the number of images input to the RIS server 1 always coincide with each other, and human errors can be reduced, which is necessary for interpretation. It is ensured that the medical image is surely present in the image server 2.

[Fifth Embodiment]
The method of the fifth embodiment according to the present invention will be described with reference to the flowchart of FIG. Step S <b> 1 is a stage in which the RIS server 1 receives information about the number of images sent from the medical imaging apparatus 4 to the image server 2 from the engineer terminal 5, and the number of images is stored in the examination information storage unit 13. Next, from Step 2 to Step S6, the RIS server 1 periodically checks the number of delivery images delivered to the image server 2, and compares the number of delivery images with the stored information on the number of images. When the number of stored images matches, the delivery completion information is stored in the information storage means 13, when it does not match, an error is displayed, and when the number of delivered images is less than the stored number of images, confirmation is repeated, When the number of delivered images is larger than the stored number of images, the confirmation is finished. Furthermore, there is a stage in which the report server 3 periodically confirms the delivery completion information of the RIS server 1. When the report server 3 receives the delivery completion information from the RIS server 1 in response to the report creation request from the report creating doctor, the display server 32 displays the order information and the examination end information, and the image server If a necessary image is called from No. 2 and the delivery completion information is not received, the report creation request is rejected. The present invention is configured in such a stage.

  By adopting such a method, it is possible to prevent a technician from forgetting delivery of a medical image to the image server 2. Therefore, the stagnation of interpretation due to the absence of the medical image in the image server 2 can be solved.
