Description

  The present invention relates to an image storage server for storing medical image data, an image storage display system constructed from image display means connected to the image storage server via a network, and an image storage display method thereof.

  Medical image diagnosis involves outputting medical images taken on modalities (medical imaging devices) such as CT (Computed Tomography), CR (Computed Radiography), MR (Magnetic Resonance), and DR (Digital Radiography) to a film, It is displayed on the display means and diagnosed (interpreted) by the doctor.

  In recent years, medical image data management systems such as PACS (Picture Archiving and Communication System) have become widespread. A system that enables communication of medical image data by connecting a network of an image storage server of a medical facility such as a hospital and an image display unit that can display an image such as a workstation by PACS is constructed.

  In the image storage server, a medical image having a single modality and a display form (layout) on the screen that is considered optimal for interpretation of the medical image are stored in advance in association with each other. When a required modality is selected, a medical image is displayed on the image display means on the PACS in an optimal display form for that single modality (see, for example, Patent Document 1).

For example, a plurality of CT images related to a patient are displayed on the image display means on the PACS, and the user arbitrarily divides the plurality of CT images into series such as a head, a chest, and an abdomen, and the display form is displayed on the image display means. Changes are being made.
JP-A-4-49945

  However, in the interpretation of a plurality of medical images acquired from the modality, it is necessary to change the display format so that the client viewer can easily interpret the image, which places a heavy burden on the user. In recent years, devices that can scan the whole body easily and quickly, such as multi-slice CT, have appeared, and it has become difficult for users to divide medical images acquired from a series of examination data into series. Therefore, cases in which the series information is not set appropriately are increasing, causing a problem in interpretation by the user.

  Further, when the user divides the series, the image recognition numbers of the medical images divided into series need to be stored in a database on the image data server side. In addition, the image recognition number stored in the database must be displayed on the client viewer side. Therefore, a load is applied to the network due to transmission / reception of the image recognition number.

  On the other hand, in a multi-modality viewer that handles a plurality of modalities, an efficient display in which images created by a plurality of modalities for a certain patient are arranged on the same screen may be desired. However, according to the conventional technology, since the display mode is the optimized display of a single modality, the medical images are displayed on the screen in an initial display. Therefore, it is necessary to change the display to a display form that is easy to interpret on the image display means side, and the user's work efficiency is poor.

  In addition, when the display is changed to a display format easy to interpret on the client viewer side, an application must be created on the client viewer side. Furthermore, in the multi-modality viewer, when similar images are displayed on the screen of the client viewer with image data such as CAD (Computer Aided Diagnosis or Detection), or when it is desired to arrange similar images around the target image. is there. In the future, it is expected that a new type of display form will be required, and applications on the client viewer side are expected to be diversified.

  The present invention has been made in view of the above-described circumstances, and provides a medical image management display system and a management display method thereof that can supply an appropriate display form of a medical image as an initial display and improve user work efficiency. For the purpose.

  Another object of the present invention is to provide a medical image management display system and a management display method thereof that can reduce the network load because it is not necessary to store the image recognition numbers by the series division in the examination.

  In order to solve the above-described problems, a medical image management display system according to the present invention has a modality for creating an image file including medical image data, and the image file has at least screen division and a frame position of the medical image. Display form information associating means for associating display form information, and medical image data included in the image file as a medical image on the screen according to the display form information associated with the image file by the display form information association means And image display means for displaying on the screen.

  In order to solve the above-described problems, the medical image management display method according to the present invention includes an image file creation process in which an image file including medical image data is created, and an image file created in the image file creation process. In accordance with the display form information associating step in which display form information associated with at least the screen division and the frame position of the medical image is associated, and the display form information associated with the image file, the medical image data included in the image file is And a display process displayed as a medical image.

  According to the medical image management display system and its management display method according to the present invention, an appropriate display form of medical images can be supplied as an initial display, so that the user's work efficiency can be improved.

  According to the medical image management display system and the management display method thereof according to the present invention, it is not necessary to store the image recognition numbers by series in the examination, and the network load can be reduced.

  A medical image data management system such as PACS (Picture Archiving and Communication System) is constructed by connecting the image storage server 12 of a medical facility such as a hospital and a client viewer 13 such as a workstation that can display images. Yes.

  The DICOM file is not necessarily generated by the modality 9 and may be generated by the image storage server 12, for example.

Although one client viewer 13 may be provided in the medical facility H ₁ as shown in FIG. 1, a plurality of client viewers 13 may be provided in the medical facility H ₁ . In addition, the client viewer 13 loads a DICOM file, analyzes a display form (layout) of a medical image, and displays it for the purpose of interpretation from a Web browser (not shown) that is application software or the image storage server 12. A method of operating and inputting graphical elements such as icons and buttons associated with instructions related to image display and processing such as the number of frames of images and image processing together with the loaded medical image using a pointing device such as a mouse. It has a GUI (Graphical User Interface) not shown.

  Here, the DICOM file generated by the modality 9 is a file generated according to the DICOM standard. The DICOM standard is a standard standardized in the United States in order to share medical information.

  FIG. 2 is a diagram illustrating an example of the structure of a DICOM file.

  As shown in FIG. 2, the DICOM file for each medical image data generated by the modality 9 includes a blank area, an accompanying information area, and an image data area. The incidental information area of the DICOM file is composed of a collection of data elements, and each data element includes a standard tag (group number and element number) and tag information (data length and data). The tag information is various attribute information related to medical images such as patient information, imaging condition information, image information, and display information.

  The patient information includes information for identifying the patient such as the patient name, patient ID (IDentification), and date of birth, and the imaging condition information includes the image type such as the primary acquisition image and the secondary acquisition image, the imaging region, and the modality 9. It includes information related to imaging conditions such as the X-ray current value and voltage value during imaging. The image information includes information indicating the examination ID and the type of the modality 9, and the display information includes information such as image contrast, image arrangement order and arrangement, and series number (group ID to which the medical image belongs). As other information, the file code of each DICOM file is included.

  For example, in a supplementary information area of a DICOM file in medical image data, a standard tag (0010,0010) indicating the patient name and tag information (TOKKYO TARO), a standard tag (aaaa, 0001) indicating the patient ID, and the tag Information (123456789-0), standard tag (bbbb, 0002) indicating the date of birth of the patient and its tag information (1942/12/25), standard tag (cccc, 0003) indicating the modality of the image and its tag Information (CT), standard tag (dddd, 0004) indicating an ID for uniquely identifying an image, tag information (1111.2222.3333.4444), standard tag (eeee, 0005) indicating an inspection comment, and subsequent data Are embedded with standard tags (ffff, 0006) representing that the image data is image data. It is assumed that the tag information of the standard tag representing the inspection comment is blank because it is less frequently used. The tag and the data length included in the data element are embedded with a numerical value in binary format, and the data is embedded with a character string in text format or a numerical value in binary format.

Further, the modality 9, the image storage server 12, the client viewer 13, and the access router 14 illustrated in FIG. 1 can perform data communication via a LAN (Local Area Network) 15 as a network in the medical facility H ₁ .

  Note that the DICOM file generated by the modality 9 may be recorded on a recording medium such as an FD, CD-ROM, or flash memory, and the image storage server 12 may obtain the DICOM file via this recording medium. Good.

  FIG. 3 is a block diagram showing the image storage server 12.

In the image storage server 12 shown in FIG. 3, the image file receiving means 21 that receives the DICOM file generated by the modality 9 via the LAN 15 and the image that stores the DICOM file received by the image file receiving means 21 In response to a request from a file storage unit 22 and a Web browser (not shown) of the client viewer 13, a Web service unit 23 that searches the image file storage unit 22 for the requested DICOM file and transmits the DICOM file; A display form information associating means 24 for associating the DICOM file with display form information having at least screen divisions and frame positions of medical images is provided. The display form information association unit 24 includes, for example, a display form information receiving unit 25 that receives display form information of a medical image from the client viewer 13 in the medical facility H ₁ or the viewer in the medical facility H ₂ , and the display Display form information embedding means 26 for embedding the display form information received by the form information receiving means 25 in the DICOM file of the image file storage means 22 is provided. The association of the display form information with the DICOM file is not limited to the case where the display form information is embedded in the DICOM file. For example, the display form information association unit 24 may have a database that associates the display form information with the DICOM file, and the DICOM file according to the display request from the client viewer 13 may be displayed according to the display form information in the database.

The image file storage means 22 can store the display form information embedded DICOM file F generated by the display form information embedding means 26, and in response to a request from the client viewer 13, the requested display form information embedded. Find the DICOM file F from the image file storage unit 22, and the client viewer 13 via the LAN15 from the Web service unit 23, which is to be sent to the medical facility _{H 2} via the network N.

  Here, in the modality 9, display form information when a medical image based on the image file created by the modality 9 is displayed alone on the screen of the client viewer 13 may be embedded in the image file.

  Next, a medical image management display method using the medical image management display system 10 will be described using the flowchart shown in FIG. In addition, although the medical image management display method when CT9a is used as the modality 9 is described, it is not particularly limited to the CT9a.

  First, imaging is performed for each patient with the CT 9a shown in FIG. 1, and a separate DICOM file is generated for each CT image data from a plurality of created CT image data. As shown in FIG. 2, this DICOM file is composed of a blank area, an accompanying information area, and an image data area, and has a standard tag defined by the DICOM standard and its tag information in the data element of the accompanying information area. In the data element, the tag and the data length are embedded with numerical values in binary format, and the data is embedded with a character string in text format or a numerical value in binary format.

  The DICOM file is received by the image file receiving means 21 of the image archiving server 12 shown in FIG. 3 via the LAN 15 under the control of the control device (not shown), and is input to the image file archiving means 22 and stored. (Step S1). The DICOM file generated by the CT 9a may be recorded on a recording medium such as an FD, a CD-ROM, or a flash memory, and the image storage server 12 may acquire the DICOM file via this recording medium.

  Further, a user such as a doctor or a nurse turns on the power, starts up the client viewer 13, operates a pointing device (not shown) such as a mouse, and enters the image storage server 12 with a required patient, for example, the patient M. The medical image display request is made.

  A DICOM file related to the patient M is retrieved from the DICOM file stored in the image file storage means 22 in step S1. The searched DICOM file related to the patient M is transmitted from the Web service means 23 to the Web browser of the client viewer 13 via the LAN 15. For example, when a DICOM file including CT image data is stored for the patient M, the DICOM file including CT image data is transmitted to the Web browser of the client viewer 13. The CT image, which is a medical image related to the patient M, is displayed on the screen of the client viewer 13 by the DICOM file transmitted in this way (step S2).

  In order to make the CT image of the patient M easy to see, the user manipulates the CT image on the GUI via a pointing device such as a mouse and drags and drops the CT image, and displays the display form, for example, screen division, CT The frame position of the image, the presence / absence of stack display of the CT image, and the stage of stack display of the CT image are changed. Here, in CT imaging, a plurality of parts may be imaged in one examination. In this case, the user changes the display form in order to classify the CT image into series for each imaging region as a subgroup of one examination.

  FIG. 5 is a diagram illustrating an example of a display form of a CT image whose display form has been changed on the screen of the client viewer 13.

FIG. 5 shows the display form of the CT image of the patient M displayed in step S2 so that the user can easily see the medical form after changing the display form, for example, six CT images P _CT-1 and P _{CT- 2} , a display screen displaying _PCT-3 , _PCT-4 , _PCT-5 and _PCT-6 .

The display screen shown in FIG. 5 is divided into “2 × 2” by the user, and the CT image P _CT-1 is displayed on the “(1, 1)” frame without stack display.

In addition, the CT image _PCT-2 is displayed in the first stage of the stack display on the frame “(1, 2)” divided into “2 × 2”. In addition, the CT image _PCT-3 is displayed in the second stage of the stack display.

Further, the CT image _PCT-4 is displayed in the first stage of the stack display on the frame “(2, 1)” divided into “2 × 2”. In addition, the CT image _PCT-5 is displayed in the second stage of the stack display, and the CT image _PCT-6 is displayed in the third stage of the stack display.

  Next, the user performs an output action of the display form information, for example, clicking an output button on the screen of the client viewer 13. When the display form information is output, the display form on the screen of the client viewer 13 is determined when the display form information is output (step S3).

When the display mode on the screen is determined, the display form information _I CT of the finalization CT image _{P CT (I CT-1,} I CT-2, I CT-3, I CT-4, I CT-5 and I _CT-6 ) is transmitted from the client viewer 13 to the display form information receiving means 25 of the image storage server 12 via the LAN 15.

FIG. 6 is a diagram illustrating an example of the display form information _ICT as a table.

6, as shown in the display screen of FIG. 5, the display form information _I CT _{(I CT-1} for each CT image after the display mode of the CT image _{P CT} is confirmed on the _{screen, I CT-2} , I _CT-3 , I _CT-4 , I _CT-5 and I _CT-6 ). The display form information _ICT includes information on screen division, frame position, stack display presence / absence, and stack display position.

Eg, CT image display form information I _CT-1 of P _CT-1, the screen split "2 × 2", the frame position "(1,1)" and no stack view showing the "S0", "2 × 2, ( 1, 1), S0 ", the display form information I _CT-2 CT images P _CT-2 is split screen" 2 × 2 ", the frame position" (1,2) "and stack displays first stage" S1 " the shown "2 × 2, (1,2), S1", the display form information I _CT-3 CT image P _CT-3, a screen split "2 × 2", the frame position "(1,2)", and “2 × 2, (1, 2), S2” indicating the second stage “S2” of the stack display, and the display form information _CT-4 of the CT image _PCT-4 are divided into “2 × 2” and frame positions. "(2,1)" and stack displays the first stage indicates "S1", "2 × 2, (2,1), S1", the display form information I _CT-5 CT image P _CT-5, the screen division “2 × 2,” frame position “(2,1)” and stack display “S2” “2 × 2, (2,1), S2” indicating the second stage, CT image P Display mode information I _CT-6 of _CT-6, the screen split "2 × 2", the frame position "(2,1)" and stack displays the third row shows the "S3", "2 × 2, (2,1 ), S3 ”.

  Next, the display form information I transmitted from the client viewer 13 shown in FIG. 3 is received by the display form information receiving means 25 of the image storage server 12 (step S4). The display form information I received by the display form information receiving unit 25 is input to the display form information embedding unit 26. In this display form information embedding means 26, the display form information I received in step S4 is embedded in the DICOM file that is the basis of the medical image whose display form is determined in step S3, and the display form information embedded DICOM file F Is generated (step S5). In the data element, the tag and the data length are embedded with numerical values in binary format, and the data is embedded with a character string in text format or a numerical value in binary format.

  Here, in step S3, display mode information may be selected according to modality 9, station name, AE (Application Entity) title, image type, and the like. In this case, the server 12 automatically generates the display form information embedded DICOM file F in step S5.

Figure 7 is a diagram showing a structural example of a display form information embedding DICOM file _{F CT.}

FIG. 7 shows the structure of the display form information embedded DICOM file F _CT-1 in which the display form information I _CT-1 input by the display form information embedding means 26 is embedded in the incidental information area of the DICOM file including CT image data. Indicates. The display form information I _CT-1 determined from the CT image _PCT-1 on the screen in step S3 is an incidental information area of the DICOM file and is embedded as tag information of a standard tag that is less frequently used and is blank. It is.

Here, a case has been described in which the display form information _ICT-1 is embedded as tag information that is an incidental information area of a DICOM file and is blank, but the present invention is not limited to this case. For example, the display form information _ICT-1 may be embedded as tag information of a private tag which is an incidental information area of a DICOM file and can set unique data. Further, the display form information _ICT-1 may be embedded in the blank area of the DICOM file.

  The display form information embedded DICOM file F generated by the display form information embedding means 26 is input and stored in the image file storage means 22 of the image storage server 12 shown in FIG. 3 (step S6). . The image storage server 12 enters a waiting state for a medical image display request, and determines whether or not there is a medical image display request from the client viewer 13 (step S7).

Here, the medical image display request is sent from the client viewer 13 in the medical facility H ₁ shown in FIG. 1 as well as other client viewers in the medical facility H ₁ and other medical facilities forming the network N network. It shall also be made from H _n.

If the determination in step S7 is Yes, that is, if there is a medical image display request regarding the patient M from the client viewer 13, the display format information embedded DICOM file F stored in the image file storage means 22 in step S6 The display form information embedded DICOM file F is retrieved. The display form embedded DICOM file F relating to the searched patient M is transmitted from the Web service means 23 to the Web browser of the client viewer 13 via the LAN 15. For example, six display-embedded DICOM files F _CT-1 , F _CT-2 , F _CT-3 , F _CT-4 , F _CT-5, and F _CT-6 containing six CT image data for the patient M are included. If stored, the display form information embedded DICOM files F _CT-1 , F _CT-2 , F _CT-3 , F _CT-4 , F _CT-5 and F _CT-6 are obtained from the Web service unit 23. The data is transmitted to the Web browser of the client viewer 13 via the LAN 15.

The screen of the client viewer 13 is once determined by the client viewer 13, and the display form information embedded DICOM files _FCT-1 , _FCT-2 , _FCT-3 , _FCT-4 , _FCT-5 and _FCT Displayed in accordance with the display form information _ICT-1 , _ICT-2 , _ICT-3 , _ICT-4 , _ICT-5, and _ICT-6 embedded in _-6 . That is, the screen of the client viewer 13 has the same display form as the screen shown in FIG. 5, and the CT images P _CT-1 , P _CT-2 , P _CT-3 , P _CT-4 , P _CT- of the patient M are displayed. ₅ and _PCT-6 are initially displayed (step S8).

In addition, regarding the CT image _PCT of the patient M displayed in step S8, the user again operates the CT image on the GUI via a pointing device such as a mouse in order to make the CT image of the patient M easy to see. However, dragging and dropping may be performed. Then, performs display form output conduct, the tag information of the display mode information embedding DICOM file F _CT, updates the display mode information is confirmed again, the flow returns to step S6.

  On the other hand, if the determination in step S7 is No, that is, if there is no medical image display request from the client viewer 13, the process returns to step S7, and the image storage server 12 enters a standby state for a medical image display request.

  In addition, as described for the CT 9a, the medical image is displayed according to the display form information for the medical image captured with the modality 9 other than the CT 9a.

  FIG. 8 is a flowchart showing a modified example of the medical image management display method using the medical image management display system 10. The system configuration of this modification of the medical image management display method is the same as the system configuration of FIGS. Further, the following description is a case where medical images taken with multi-modality are displayed side by side. In addition, although the medical image management display method in the case of multimodality combining CT9a, MR9b, and CR9c will be described as modality 9, it is not particularly limited to the combination of CT9a, MR9b, and CR9c.

  First, CT9a, MR9b, and CR9c shown in FIG. 1 each perform imaging for each patient, and separate DICOM files are generated for each medical image data from the created medical image data.

  The DICOM file is received by the image file receiving means 21 of the image archiving server 12 shown in FIG. 3 via the LAN 15 under the control of the control device (not shown), and is input to the image file archiving means 22 and stored. (Step S11).

  Furthermore, a user such as a doctor or a nurse turns on the power, starts up the client viewer 13, operates a pointing device (not shown) such as a mouse, and displays a medical image related to the patient M on the image storage server 12. Make a request.

  The DICOM file related to the patient M is searched from the DICOM file stored in the image file storage means 22 in step S11. The searched DICOM file related to the patient M is transmitted from the Web service means 23 to the Web browser of the client viewer 13 via the LAN 15. For example, when a display form embedded DICOM file including CT image data, MR image data, and CR image data is stored for the patient M, the DICOM file including CT image data, MR image data, and CR image data is stored in the client viewer 13. To the web browser. The CT image, MR image, and CR image that are medical images of the patient M are displayed on the screen of the client viewer 13 by the DICOM image file transmitted in this manner (step S12).

  In order to make it easy to see the medical image of the patient M, the user operates the medical image on the GUI via a pointing device such as a mouse and drags and drops the medical image, and the display form, for example, screen division, medical The image frame position, medical image stack display presence / absence, medical image stack display stage, and medical image enlargement ratio are changed.

  FIG. 9 is a diagram illustrating an example of a display form of a medical image whose display form has been changed on the screen of the client viewer 13.

FIG. 9 shows the medical image displayed in step S12 changed so that the user can easily see the medical image after changing the display mode, for example, two CT images P _CT-1 and P _CT-2 , It is a display screen displaying three MR images _PMR-1 , _PMR-2, and _PMR-3, and one CR image _PCR .

The display screen shown in FIG. 9 is divided into “2 × 2” by the user, and the CT images P _CT-1 and P _CT-2 are displayed in a stack on the frame of “(1, 2)”. It is displayed with an enlargement ratio of “0.5”.

In addition, MR images _PMR-1 , _PMR-2, and _PMR-3 are stacked on the frame “(2, 2)” divided into “2 × 2”, and the enlargement ratio is “1”. It is displayed.

Further, the CR image _PCR is displayed at the enlargement ratio “1” on the frame “(1,1)-(2,1)” divided into “2 × 2” without stack display.

  Next, the user performs an output action of the display form information, for example, clicking an output button on the screen of the client viewer 13. When the display form information is output, the display form on the screen of the client viewer 13 is determined when the display form information is output (step S13).

When the display form on the screen is confirmed, the display form information I ( _ICT-1 , _ICT-2 , _IMR-1 , _IMR-2 , _IMR-3, and _ICR ) of the medical image after the confirmation is established. Is transmitted from the client viewer 13 to the display form information receiving means 25 of the image storage server 12 via the LAN 15.

  FIG. 10 is a diagram showing an example of the display form information I as a table.

FIG. 10A shows the display form information I (I _CT-1 , I _CT-2 , I _{MR) for} each medical image after the display form is fixed on the screen as displayed on the display screen of FIG. _-1 , _IMR-2 , _IMR-3 and _ICR ). The display form information I includes information on screen division, frame position, stack display presence / absence, and enlargement ratio.

For example, the display form information I _CT-1 and I _CT-2 of the CT images P _CT-1 and P _{CT- 2} is divided into “2 × 2”, frame position “(1, 2)”, and stack display “ S ”and“ 2 × 2, (1, 2), S, 0.5 ”indicating an enlargement ratio“ 0.5 ”, display form information I _{MR-1 of} MR images P _MR-1 , P _MR-2, and P _MR-3 , I _MR-2 and I _MR-3 are “2 × 2, (2 × 2,” indicating screen division “2 × 2”, frame position “(2,2)”, stack display “S” and enlargement ratio “1”. 2, 2), S, 1 ”, and the display form information _ICR of the CR image _PCR is divided into“ 2 × 2 ”, frame position“ (1,1)-(2,1) ”, stack display It is assumed that “2 × 2, (1,1)-(2,1), 0, 1” indicating “0” for none and an enlargement ratio “1”.

As shown in FIG. 9, when medical images created with different modalities 9 are displayed side by side on the same screen of the client viewer 13, the display form information I for each medical image may be expressed in a unified manner. For example, when a CT image, an MR image, and a CR image are displayed side by side on the same screen, as shown in FIG. 10B, the display form information I of the CT image, the MR image, and the CR image is divided into “2 × 2 ", the frame position of the CT image P _CT" CT- (1, 2) ", the stack display has" CT-S "and magnification as" CT-0.5 ", the frame position of the MR images P _MR" MR- ( 2,2) ", there stack display" MR-S "and magnification" MR-1 ", the frame position of the CR image P _CR" CR- (1,1) - (2,1) ", no stack display "2x2, CT- (1,2), CT-S, CT-0.5, MR- (2,2), MR-S, MR" indicating "CR-0" and enlargement ratio "CR-1" -1, CR- (1,1)-(2,1), CR-0, CR-1 ".

  Next, the display form information I transmitted from the client viewer 13 shown in FIG. 3 is received by the display form information receiving means 25 of the image storage server 12 (step S14). The display form information I received by the display form information receiving unit 25 is input to the display form information embedding unit 26. In this display form information embedding means 26, the display form information I received in step S14 is embedded in the DICOM file that is the basis of the medical image whose display form is determined in step S13, and the display form information embedded DICOM file F Is generated (step S15). In the display form data element, the tag and the data length are embedded with numerical values in binary format, and the data is embedded with a character string in text format or a numerical value in binary format.

  The display form information embedding DICOM file F generated by the display form information embedding means 26 is input and stored in the file storage means 22 of the image storage server 12 (step S16). The image storage server 12 enters a waiting state for a medical image display request, and determines whether there is a medical image display request from the client viewer 13 (step S17).

If the determination in step S17 is Yes, that is, if there is a request for displaying a medical image related to the patient M from the client viewer 13, the display form information embedded DICOM file F stored in the image file storage means 22 in step S16 The display form embedded DICOM file F is retrieved. The display form embedded DICOM file F relating to the searched patient M is transmitted from the Web service means 23 to the Web browser of the client viewer 13 via the LAN 15. For example, two display form embedded DICOM files F _CT-1 and F _CT-2 containing two CT image data for the patient M, and three display form embedded DICOM files F _MR-1 containing three MR image data , F _MR-2 and F _MR-3 and one display form embedded DICOM file F _CR including one CR image data are stored, these display form embedded DICOM files F _CT-1 , F _{CT-2, F MR-1} , F MR-2, F MR-3 and _{F CR} is transmitted from the Web service unit 23 to the Web browser of the client viewer 13 via the LAN 15.

The screen of the client viewer 13 is once determined by the client viewer 13 and is displayed in the display form embedded DICOM files F _CT-1 , F _CT-2 , F _MR-1 , F _MR-2 , F _MR-3, and F _CR . It is displayed according to the embedded display form information I _CT-1 , I _CT-2 , I _MR-1 , I _MR-2 , I _MR-3, and I _CR . That is, on the screen of the client viewer 13, the CT images _PCT-1 and _PCT-2 of the patient M, the MR images _PMR-1 , _PMR-2, and _PMR-3 and CR image _PCR are initially displayed (step S18). Here, the CT image and MR image on which the stack display is performed are sorted by image number, image UID (Unique IDentifier), creation date and time, respectively.

  For the medical image of the patient M displayed in step S18, the user again operates the medical image on the GUI via a pointing device such as a mouse to make the medical image easier to see, and drags and drops the medical image. Etc. may be performed. Then, the display form output action is performed, the display form information confirmed again in the tag information of the display form information embedded DICOM file F is updated, and the process returns to step S16.

  On the other hand, if the determination in step S17 is No, that is, if there is no medical image display request from the client viewer 13, the process returns to step S17, and the image storage server 12 enters a standby state for a medical image display request.

  In some cases, similar images are displayed on the screen of the client viewer 13 with image data such as CAD (Computer Aided Diagnosis or Detection), or similar images are arranged around a target image. In this case, the display form embedding DICOM file F embeds a dot serving as the starting point of the image end, for example, the upper left end point of the image, and a dot serving as the end point of the image end, for example, the lower right end point of the image.

  For example, the leftmost upper end point and the rightmost lower end point “(50,50)-(600,600)” of the medical image are embedded in the display form embedded DICOM file F. The medical image based on the display form embedded DICOM file F in which the leftmost upper end point and the rightmost lower end point “(50,50)-(600,600)” of the medical image are embedded is represented by dot coordinates (50 , 50) is aligned with the upper left end of the image, and the dot coordinate (600, 600) is aligned with the lower right end of the image.

  In addition, when the leftmost uppermost point and the lowermost rightmost point “(50,50)-(600,600), S1” of the medical image are embedded in the display form embedded DICOM file F, the medical image may be displayed in a stack display. it can. Note that, as described in the multi-modality of CT9a, MR9b, and CR9c, the medical image is displayed according to the display form information for the medical image captured with multimodalities other than CT9a, MR9b, and CR9c.

In addition, about the structural means member of FIG. 13, the same code | symbol is attached | subjected to the same structural member as FIG. 3, and description is abbreviate | omitted. Further, the association of the display form information with the DICOM file is not limited to the case where the display form information is embedded in the DICOM file.

  FIG. 14 is a diagram showing an example of the display form information I stored in the display form information storage unit 30 as a table.

  The display form information storage unit 30 of the image storage server 12A shown in FIG. 13 stores a comparison table between the classification of medical image data displayed on the screen and the display form information corresponding to the classification. For example, the medical image data is classified by at least one of the modality 9 of the generation source, the station name, the AE title, the image processing type, and the fusion.

  For example, when medical image data is classified according to the type of modality 9 and only CT image data exists as medical image data, the screen division “2 × 2” and the CT image frame position “(1 , 1)-(2,2) ”,“ CT-S ”with stack display and“ 2 × 2, CT- (1,1)-(2,2), CT-S ” , CT-0.5 ”. Further, when CT image data, MR image data, and CR image data exist as medical image data, the screen division “2 × 2” and the CT image frame position “CT- (1, 2) are displayed as the display form information I. ”,“ CT-S ”with stack display and“ CT-0.5 ”magnification, MR image frame position“ MR- (2,2) ”,“ MR-S ”with stack display and“ MR-1 ” ”,“ 2 × 2, CT- ”indicating the CR image frame position“ CR- (1,1)-(2,1) ”, no stack display“ CR-0 ”and enlargement ratio“ CR-1 ” (1,2), CT-S, CT-0.5, MR- (2,2), MR-S, MR-1, CR- (1,1)-(2,1), CR-0, CR- Match 1 ”.

  Here, in the modality 9, display form information when a medical image based on the image file created by the modality 9 is displayed alone on the screen of the client viewer 13 may be embedded in the image file.

  In the present embodiment, the image storage server 12A of the medical image management display system 10A is provided with display form information association means 24A, and the image storage server 12A performs display according to the correspondence table of the display form information storage means 30. The case where the form information I is embedded in the DICOM file is shown. In the image storage server 12A, since DICOM files generated by a plurality of modalities 9 are centrally managed, a display in the case of displaying various medical images created by a multi-modality for a certain patient on the same screen is particularly important. The form can be set. However, the display form information association unit 24 shown in FIG. 13 may be provided in the modality 9 or the client viewer 13 of the medical image management display system 10 shown in FIGS.

  Next, a medical image management display method using the medical image management display system 10A will be described using the flowchart shown in FIG. In addition, although the medical image management display method in the case of multimodality combining CT9a, MR9b, and CR9c will be described as modality 9, it is not particularly limited to the combination of CT9a, MR9b, and CR9c. Moreover, it is not limited to the case of multi-modality.

  First, CT9a, MR9b, and CR9c shown in FIG. 12 respectively perform imaging for each patient, and separate DICOM files are generated for each medical image data from the created medical image data.

  Under the control of the control device (not shown), the DICOM file is received by the image file receiving means 21 of the image storage server 12A shown in FIG. 13 via the LAN 15, and input to the image file storage means 22 and stored. (Step S21).

  In the display form information embedding unit 26, the display form information I corresponding to the classification by the modality 9 of the medical image data is read from the display form information storage unit 30 (step S22). For example, when CT image data, MR image data, and CR image data are stored in the image file storage unit 22 for the patient M, “2 × 2, CT− ( 1,2), CT-S, CT-0.5, MR- (2,2), MR-S, MR-1, CR- (1,1)-(2,1), CR-0, CR-1 "Is read.

The display form information embedding unit 26 embeds the display form information I read in step S22 in the DICOM file including CT image data, MR image data, and CR image data, and the display form information embedded DICOM file F is obtained. It is generated (step S23). For example, display form information embedded DICOM files F _CT-1 and F _CT-2 from a DICOM file including two CT image data are displayed, and display form information embedded DICOM file F _MR- from a DICOM file including three MR image data are displayed. ₁ , F _MR-2 and F _MR-3 , a display form information embedded DICOM file _FCR is generated from a DICOM file including one CR image data, input to the image file storage means 22 and stored. (Step S23).

  The image storage server 12 enters a waiting state for a medical image display request, and determines whether there is a medical image display request from the client viewer 13 (step S25).

If the determination in step S25 is Yes, that is, if there is a medical image display request regarding the patient M from the client viewer 13, the display form embedded DICOM file F stored in the image file storage means 22 in step S23 is related to the patient M. The display form embedded DICOM file F is searched. The display form embedded DICOM file F relating to the searched patient M is transmitted from the Web service means 23 to the Web browser of the client viewer 13 via the LAN 15. For example, two display form embedded DICOM files F _CT-1 and F _CT-2 containing two CT image data for the patient M, and three display form embedded DICOM files F _MR-1 containing three MR image data , F _MR-2 and F _CT-3 and one display form embedded DICOM file F _CR including one CR image data are stored, these display form embedded DICOM files F _CT-1 , F _{CT-2, F MR-1} , F MR-2, F MR-3 and _{F CR} is transmitted from the Web service unit 23 to the Web browser of the client viewer 13 via the LAN 15.

On the screen of the client viewer 13, the display form information embedded in the display form information embedded DICOM files _FCT-1 , _FCT-2 , _FMR-1 , _FMR-2 , _FMR-3, and _FCR Accordingly, the CT images P _CT-1 and P _CT-2 , the MR images P _MR-1 , P _MR-2, and P _MR-3, and the CR image P _CR are initially displayed (step S26).

  On the other hand, if the determination in step 25 is No, that is, if there is no medical image display request from the client viewer 13, the process returns to step S25, and the image storage server 12 enters a standby state for a medical image display request.

  Next, a modified example of the medical image management display method using the medical image management display system 10A will be described using the flowchart shown in FIG. In addition, although the medical image management display method in the case of multimodality combining CT9a, MR9b, and CR9c will be described as modality 9, it is not particularly limited to the combination of CT9a, MR9b, and CR9c. Moreover, it is not limited to the case of multi-modality.

  First, CT9a, MR9b, and CR9c shown in FIG. 12 respectively perform imaging for each patient, and separate DICOM files are generated for each medical image data from the created medical image data.

  Under the control of the control device (not shown), the DICOM file is received by the image file receiving means 21 of the image storage server 12A shown in FIG. 13 via the LAN 15, and input to the image file storage means 22 and stored. (Step S31).

  The image storage server 12 enters a waiting state for a medical image display request, and determines whether or not there is a medical image display request from the client viewer 13 (step S32).

  If the determination in step S32 is Yes, that is, if there is a medical image display request regarding the patient M from the client viewer 13, the display form information embedding unit 26 displays the display corresponding to the classification by the modality 9 of the medical image data regarding the patient M. The form information I is read from the display form information storage means 30 (step S33). For example, when CT image data, MR image data, and CR image data are stored for the patient M in the image file storage unit 22 in step S31, “2 × 2, CT as the display form information I from the table of FIG. -(1,2), CT-S, CT-0.5, MR- (2,2), MR-S, MR-1, CR- (1,1)-(2,1), CR-0, CR -1 "is read.

The display form information embedding unit 26 embeds the display form information I read in step S33 in the DICOM file including CT image data, MR image data, and CR image data, and the display form information embedded DICOM file F is obtained. It is generated (step S34). For example, two display form information embedded DICOM files F _CT-1 and F _CT-2 from a DICOM file including two CT image data are converted into three display form information embedded DICOMs from a DICOM file including three MR image data. A display form information embedded DICOM file _FCR is generated from the files _FMR-1 , _FMR-2, and _FMR-3 , and from a DICOM file including one CR image data.

The display form embedded DICOM files F _CT-1 , F _CT-2 , F _MR-1 , F _MR-2 , F _MR-3, and F _CR generated in step S 34 are transmitted from the Web service unit 23 via the LAN 15 to the client. It is transmitted to the web browser of the viewer 13.

On the screen of the client viewer 13, according to the display form information I embedded in the display form information embedded DICOM file F, the CT images P _CT-1 and P _{CT-2 of} the patient M and the MR images P _MR-1 , P _MR-2 and _PMR-3 and the CR image _PCR are initially displayed (step S35).

  On the other hand, if the determination in step 32 is No, that is, if there is no medical image display request from the client viewer 13, the process returns to step S 32, and the image storage server 12 again enters a standby state for a medical image display request.

  In some cases, similar images are displayed on the screen of the client viewer 13 with image data such as CAD, or similar images are arranged around a target image. In that case, the display form embedded DICOM file embeds dots that are the starting point of the image end, for example, the upper left end point of the image, and the dot that is the end point of the image end, for example, the lower right end point of the image.

  Further, in the present embodiment, a case has been described in which display form information is embedded directly in the DICOM file to generate a display form information embedded DICOM file in order to associate the DICOM file with the display form information. However, the present invention is not limited to this. For example, a means for comparing the DICOM file and the display form information may be provided, and the display form information corresponding to the desired DICOM file may be read from the means.

  According to the medical image management display method using the medical image management display system 10A or a modification thereof, an appropriate display form of medical images can be supplied as an initial display, so that the user's work efficiency can be improved.
