<P>PROBLEM TO BE SOLVED: To effectively display incidental information without obstructing the visibility of a medical image. <P>SOLUTION: In the storage device 32 of a report preparation terminal unit 13, a property table 70 is stored. In the property table 70, property information showing the relevance of each item of the incidental information of the medical image 17 is stored. Prior to the display of an image display screen 46, a region setting section 42 extracts the main photographic subject display region 60 of the medical image 17 and sets either one excepting the main photographic subject display region 60 as a candidate region for an incidental information display region 61. A display configuration determining section 43 calculates a necessary region which is required for the display of each item of the incidental information and judges whether the incidental information can be stored in the candidate region or not. The display configuration determining section 43 performs the judgement again by sorting items into a group for each property when the fact that the incidental information cannot be stored in the candidate region is judged and determines the display configuration of each item. <P>COPYRIGHT: (C)2010,JPO&INPIT

Description

  The present invention relates to a medical image display device, a medical image display method, and a medical image display program for displaying a medical image and its supplementary information superimposed on a display screen.

  In recent medical practice, various computer systems for handling medical documents such as medical records and medical reports (hereinafter simply referred to as reports) as electronic data and facilitating the creation and management of medical documents are being introduced. Among them, the report creation support system is greatly utilized when creating reports.

  The report creation support system includes a report creation terminal that creates a report and a database (hereinafter abbreviated as DB) server that stores data of the created report. The DB server stores medical image data in addition to report data. A medical image is taken by a modality (medical examination apparatus) such as a CR (Computed Radiography) apparatus, a CT (Computed Tomography) apparatus, or an MRI (Magnetic Resonance Imaging) apparatus.

  The report creation terminal is operated by, for example, a doctor who specializes in image diagnosis (hereinafter referred to as an interpreting doctor), and the interpretation doctor observes and recognizes a medical image, such as an observation record such as a lesion state, that is, input of findings. Accept. The report creation terminal has an editing function for collecting input findings data into a report. A medical image referred to when creating a report is displayed on a display of a report creation terminal or a dedicated display, and this is observed by an interpreting doctor.

  The DB server stores reports and medical image data in a readable state through the network. A doctor in the medical department who requested the interpretation (hereinafter referred to as the requesting doctor) accesses the DB server through the medical department terminal located in the clinical department, reads the data of the report or medical image to the medical department terminal, and browses them. To do.

  Various incidental information such as patient ID, patient name, sex, date of birth, examination ID, examination date (imaging date), imaging conditions, examination type, etc. are added to the medical image. The incidental information is information that serves as an index when creating a report, and is displayed on the same screen together with the medical image.

  Patent Document 1 discloses a medical image display device that defines a display form of medical images and incidental information. For example, the largest one of the plurality of tomographic image portions of the subject is recognized, the image area is obtained, and the accompanying information is displayed so as not to overlap the image area. In the “character priority, image movement method” of the first embodiment or the “image priority character display method” of the second embodiment, either the image area or the display area of the accompanying information is moved to avoid duplication of these. is doing.

Further, as a third embodiment, a “region of interest setting method” in which an interpreting doctor designates a region of interest (hereinafter abbreviated as ROI) on the screen so that the display region of ROI and incidental information does not overlap. As Example 4, there is also described an “image reduction method” in which a medical image is reduced and displayed according to the amount of auxiliary information to be displayed, and avoiding duplication with the auxiliary information.
JP 2007-185215 A

  Since the medical image is data that forms the basis of diagnosis, it is preferable to display the image as clearly and as precisely as possible. On the other hand, in the incidental information, there are items that are related to each other that are desired to be viewed together when creating an interpretation or report, and items that are not. For this reason, it is preferable to display items with high relevance as much as possible. In addition, the relevance of each item of incidental information varies depending on the requesting doctor, the interpreting doctor, the patient to be examined, and the like.

  In Examples 1 and 2 of Patent Document 1, one of the display areas for medical images or incidental information is fixed and the other is moved. Although it is described that the display area of medical images or incidental information does not protrude from the display screen, the amount of movement of the display area is limited because the display screen is finite. Accordingly, there may be cases where the display areas overlap. If each display area overlaps, it becomes difficult to see medical images or incidental information, which may lead to medical errors such as misdiagnosis and oversight of lesions.

  Further, if the display area for medical images or supplementary information is moved, there is a problem in that comparison with past medical images does not remain because the display position is shifted from the normal display position. In particular, when the display area of a medical image is moved and a moving image is displayed, the display position of the medical image changes for each frame, which makes it very difficult to observe.

  In the third embodiment, since the ROI is designated by the interpretation doctor, the operation is troublesome. In the fourth embodiment, since application to a medical image to be pasted on a report that does not require detailed interpretation is assumed, image quality deterioration due to reduction is not a problem. However, when applied to medical images used for interpretation, there is a problem that accurate diagnosis cannot be made due to image quality degradation.

  As a solution to the above problem, it is conceivable to devise the display of the incidental information by changing the arrangement of the incidental information or appropriately assigning the display area of the incidental information without processing the medical image. However, if the order of the incidental information is changed or the display area of the incidental information is assigned to the dark clouds, related items may be displayed at a distant position, and there is no unity as information, and line-of-sight movement is lost. A new problem of troublesomeness arises.

  The present invention has been made in view of the above problems, and an object thereof is to effectively display incidental information without impairing the visibility of a medical image.

In order to achieve the above object, the medical image display apparatus of the present invention superimposes additional information on medical images and medical images consisting of m ₀ items (m ₀ is a natural number of 2 or more) on a display screen. Items having the same attribute in the auxiliary information display area provided outside the main subject display area in the medical image based on the display control means to be displayed and the attribute information defining the attribute of each item of the auxiliary information. And a display form determining means for determining the display form of the supplementary information so as to be displayed together.

  It is preferable to include a region setting unit that analyzes the medical image, extracts a main subject display region, and sets a candidate region for the incidental information display region outside the extracted main subject display region.

  The display form determining means compares the size of the necessary area necessary for displaying the supplementary information with the candidate area size of the supplementary information display area, and determines whether the supplementary information fits in the candidate area.

Attributes have a hierarchical structure. The display type determining unit, m _n-1 or with the same attributes of the n-1 hierarchy (n is a natural number of 1 or more) (≦ m ₀ pieces) scores (n = 1 all items in the case of) the It is determined whether or not the candidate area can be accommodated. When it is determined that the item does not fit in the candidate area, the display form determination means determines that the _mn items having the same attribute of the nth layer (<m _n-1 items) that are the layers below the n-1th layer. In addition, it is determined whether or not at least two of the _mn-1 items fit within the candidate area.

  If the display form determining unit determines that an item having the same attribute in the n-th layer does not fit in the candidate area when n is a preset upper limit value, whether each item fits in the candidate area Determine whether or not.

  When the display form determining means determines that an item fits in the candidate area, at least the necessary area of the item in the candidate area is assigned to the incidental information display area of the item. If there is another item whose display form has not been determined, it is determined whether or not the other item fits in an area obtained by removing the amount assigned to the incidental information display area from the candidate area.

  The display form determining means assigns the incidental information display area to the priority display area defined for each attribute.

  It is preferable to include a storage control unit that stores information on the display mode determined by the display mode determination unit in association with a medical image.

  The incidental information has at least two items of patient-related items related to patients undergoing medical examinations, imaging-related items related to imaging of medical images, and image-related items related to medical images. The same attribute is defined.

  The medical image display method of the present invention is a medical image display method for displaying medical images and supplementary information of a medical image composed of a plurality of items on the screen of a display, and each item of the supplementary information Attached information display form so that items having the same attribute are collectively displayed in the accompanying information display area provided outside the main subject display area in the medical image based on the attribute information defining the attributes of And a display control step for controlling display of medical images and supplementary information in accordance with the display mode determined in the display mode determination step.

  The medical image display program of the present invention is a medical image display program for displaying medical images and supplementary information of a medical image composed of a plurality of items on a display screen, and each item of the supplementary information Attached information display form so that items having the same attribute are collectively displayed in the accompanying information display area provided outside the main subject display area in the medical image based on the attribute information defining the attributes of And a display control function for controlling display of medical images and supplementary information in accordance with the display mode determined by the display mode determination function.

  According to the present invention, since items having the same attribute are displayed together without modifying the medical image, the incidental information can be effectively displayed without impairing the visibility of the medical image. it can.

The medical department terminal 11 is used when issuing an order for requesting the examination to the examination department 12 in addition to viewing and inputting the medical chart 16. The medical department terminal 11 displays the medical image 17 and the report 18 provided from the examination department 12 and provides them for browsing by the requesting doctor.

  The report creation terminal 13 is operated by a doctor of the examination department 12 specializing in interpretation (hereinafter referred to as an interpretation doctor). The report creation terminal 13 is used when the interpretation doctor confirms the order or creates the report 18. The report creation terminal 13 supports the creation of the report 18 by displaying an image display screen 46 and a report edit screen 47 (see FIG. 3).

  In the DB server 14, a plurality of DBs such as a medical record DB 19, an image DB 20, and a report DB 21 are constructed. The medical record DB 19 stores medical record 16 data for each patient. The image DB 20 stores data of a medical image 17 captured by a modality (medical examination device) 22 such as a CR device, a CT device, or an MRI device. The report DB 21 stores data of the report 18 created by the report creation terminal 13.

  The DB server 14 receives the data of the medical image 17 from the modality 22 through the network 15 and stores the received data of the medical image 17 in the image DB 20. That is, the DB server 14 functions as a so-called PACS (Picture Archiving and Communication Systems) server and constitutes a PACS together with the modality 22.

  The data of the medical image 17 has an image ID for identifying each medical image 17. The data of the medical image 17 is stored in the image DB 20 in a file format conforming to DICOM (Digital Imaging and Communication in Medicine), for example. The DICOM tag that records incidental information including various items such as patient ID, patient name, gender, date of birth, examination ID, examination date (imaging date), imaging conditions, examination type is assigned to the medical image 17 file. Is done. The data of the medical image 17 stored in the image DB 20 can be searched using various items of the DICOM tag as search keys.

  The DB server 14 constitutes a medical chart system together with the medical department terminal 11 and the medical chart DB 19. The DB server 14 constitutes a report creation support system together with the report creation terminal 13, the image DB 20, and the report DB 21. The data of the report 18 can be searched using search keys such as examination ID, patient ID, patient name, etc., like the data of the medical image 17. In addition, in this example, although each DB19-21 was demonstrated in the example constructed | assembled in one DB server 14, you may construct | assemble each DB19-21 in a separate DB server.

  The order issued by the medical department terminal 11 includes the patient ID, patient name, request date, request source, examination type (CT, MRI, etc.), examination purpose, necessity of interpretation, comments from the requesting doctor, etc. It has various items for recording information. Some of these items (requester, comment information, etc.) are also handled as supplementary information of medical images. Information such as the affiliation, name, and doctor ID of the requesting doctor such as internal medicine and brain surgery is recorded in the request source item. Information such as a therapeutic effect determination for determining a therapeutic effect on a lesion being treated and a metastasis search for examining the presence or absence of a metastatic lesion are recorded in the items for examination.

  The order issued by the clinical department terminal 11 is transmitted to an order reception terminal (not shown) installed in the examination department 12 and accepted by the examination department 12. The order receiving terminal assigns an inspection ID to the received order and manages the order data. The examination ID is transmitted from the order reception terminal to the clinical department terminal 11 together with the reception completion notification. The staff (inspection engineer) of the examination department 12 performs imaging by the modality 22 based on the order received at the order reception terminal.

  When interpretation is necessary (when an item for whether or not order interpretation is necessary), an order with an examination ID is transmitted from the order reception terminal to the report creation terminal 13. The interpretation doctor confirms the order via the report creation terminal 13 and reads out the data of the medical image 17 to be interpreted from the image DB 20. Then, the interpretation results of the read medical image 17 are collected in a report 18.

  When the creation of the report 18 is completed, the interpretation doctor transmits a creation completion notice to the order issuer's department terminal 11 through the report creation terminal 13. The creation completion notification includes the addresses in the DBs 20 and 21 where the medical image 17 and the report 18 are stored. The requesting physician accesses the address included in the creation completion notification through the medical department terminal 11 and browses the medical image 17 and the report 18.

  In the medical department terminal 11, client programs such as chart software for browsing and editing the chart 16 and viewer software for browsing the medical image 17 and the report 18 are installed as the AP 36. When the client program is activated, an operation screen using a GUI (Graphical User Interface) is displayed on the display 37 of the medical department terminal 11. The operation screen includes a display screen for displaying the medical chart 16, the medical image 17, and the report 18 read from the medical chart DB 19, the image DB 20, and the report DB 21, respectively.

  The medical department terminal 11 receives an operation instruction such as an instruction to input / edit the medical chart 16 and an instruction to input / issue an order through the input device 38. The input chart 16 and order data are stored in the chart DB 19.

  A report editing client program for supporting report creation is installed in the report creation terminal 13 as an AP 36. The report creation terminal 13 performs display processing of the medical image 17 and editing processing of the report 18 by a client program for editing the report.

  In the DB server 14, a server program is installed as the AP 36, which executes processing in response to requests from the terminals 11 and 13 as clients and responds with processing results.

  In FIG. 3, when the CPU 30 of the report creation terminal 13 starts a report editing client program, a console control unit (corresponding to display control means) 40, a DB access part (corresponding to storage control means) 41, and an area setting unit 42. , Function as a display form determination unit 43, an edit processing unit 44, and an order acquisition unit 45.

  The report creation terminal 13 has a configuration in which two displays 37 a and 37 b are connected to a terminal body provided with a CPU 30. An image display screen 46 used for observing the medical image 17 is output to one display 37a. A report editing screen 47 used to create the report 18 is output to the other display 37b.

  The image display screen 46 and the report edit screen 47 constitute a GUI operation screen. The console control unit 40 outputs these operation screens to the respective displays 37a and 37b, and accepts input of operation instructions from the input device 38 through the operation screens.

  The image display screen 46 and the report edit screen 47 are activated in conjunction. When an examination ID including the medical image 17 to be interpreted is input from the report editing screen 47, the console control unit 40 acquires the data of the medical image 17 corresponding to the examination ID from the image DB 20 through the DB access unit 41. To do. The console control unit 40 activates the image display screen 46 when outputting the acquired medical image 17 to the display 37a.

  The image display screen 46 displays various medical images 17 such as a fluoroscopic image captured by a CR apparatus, a tomographic image captured by a CT apparatus or an MRI apparatus, and a three-dimensional image generated based on the tomographic image. Is done. The image display screen 46 can display a list of a plurality of medical images 17 simultaneously, such as arranging and displaying six-frame tomographic images on one screen. When one frame is selected from the six-frame tomographic images, only the tomographic image can be displayed on one screen (see FIG. 4). The image display screen 46 is provided with various operation tools constituting the GUI such as operation buttons, list boxes, and icons. Various operation instructions are input from the input device 38 through such an operation tool.

  In FIG. 4 showing an example in which a tomographic image captured by a CT apparatus or an MRI apparatus is displayed on the image display screen 46 as a medical image 17, the image display screen 46 includes a main subject display area 60 and an accompanying information display area 61. Divided. The size and arrangement of the display areas 60 and 61 are set by the area setting unit 42. In addition, the display form of the accompanying information in the accompanying information display area 61 is determined by the display form determining unit 43.

  The main subject display area 60 constitutes a main part of the subject (in this case, an abdominal CT tomographic image) displayed on the medical image 17 and is arranged substantially at the center. The supplementary information display area 61 displays a list of supplementary information of the medical image 17 and is arranged in the upper part of the main subject display area 60.

  In the incidental information display area 61, a total of 14 items are displayed in three rows. In the first section 62 in the first column on the left, items of “patient name”, “patient ID”, “sex, date of birth”, “height, weight”, and “examination type” are displayed. In the second section 63 in the second row in the center, items of “imaging date”, “imaging condition”, “imaging region”, “imaging time”, and “contrast agent” are displayed. The third section 64 in the third column on the right side has “series number”, “number of pixels”, “window width (display density width of tomographic image)”, and “window level (display center density of tomographic image)”. Items are displayed.

The boundary line 65 between the first section 62 and the second section 63 and the boundary line 66 between the second section 63 and the third section 64 are the total width W ₀ of the incidental information display area 61 and the width w _{i of the} character string (FIG. 5). Each section 62 is considered in consideration of items having relatively large references (“sex, date of birth” in the first section 62, “imaging conditions” in the second section 63, “window level” in the third section 64). The items of .about.64 are set to appropriate values in advance so as not to protrude as much as possible to other sections (in the case of the third section 64, outside the image display screen 46).

  Returning to FIG. 3, the report editing screen 47 is provided with a plurality of finding text input areas 48 in addition to various operation tools and incidental information display areas similar to the image display screen 46. Various operation instructions are input from the input device 38 through such an operation tool. The operation instruction is performed by, for example, placing the pointer 49 on a desired operation tool and clicking the mouse. The operation instructions include an instruction to read the report 18 data from the report DB 21, an instruction to save the report 18 data to the report DB 21, an instruction to select the observation text input area 48 and make it active (a state where input is possible), and the like. included.

  In the observation sentence input area 48, observation records such as the state of the lesion recognized by the interpretation doctor by observing the medical image 17 through the image display screen 46, that is, a sentence (finding sentence) indicating the observation is input. The observation text input area 48 is used to input findings separately for each lesion when there are a plurality of lesions, or for each examination purpose when there are a plurality of examination purposes (for example, treatment effect determination and metastasis search). It is used such as typing separately. It is also possible to use a method in which a plurality of interpreting doctors input their findings, such as a resident doctor and a supervising doctor, an interpreting doctor who performs primary interpretation, and an interpreting doctor who performs secondary interpretation.

  The data of the finding sentence input to the finding sentence input area 48 (hereinafter referred to as finding data) has a finding ID for identifying each individual. The finding ID is used for associating the medical image 17 or the report 18 with the finding sentence, and includes a number assigned in the order in which the finding sentence input area 48 is added. A finding ID of “F−N” is assigned to the finding sentence input to the N-th finding sentence input area 48 (N is a natural number of 1 or more).

  After creating the report 18 on the report editing screen 47, when an instruction to save the data of the report 18 is given, the data of the report 18 is confirmed and saved in the report DB 21. Editing of the report 18 that has been confirmed and saved is prohibited in order to prevent unauthorized tampering. Of course, it is also possible to temporarily store the data of the report 18 being created in the report DB 21.

  The DB access unit 41 transmits a processing request to the DB server 14 and receives a processing result based on commands from the console control unit 40 and the editing processing unit 44. The processing request for the image DB 20 includes a search request for searching the medical image 17 using information such as an examination ID and an image ID as search keys. The processing request for the report DB 21 includes a storage request for storing the data of the generated report 18, and a search request for the data of the generated report 18 and the data of the report 18 being generated.

  The DB access unit 41 receives the data that is the target of the storage request from the editing processing unit 44 and transmits it to the DB server 14. In addition, the search request target data is received from the DB server 14 and delivered to the console control unit 40, the region setting unit 42, and the display form determination unit 43.

  First, the region setting unit 42 performs binarization processing on the data of the medical image 17 received from the DB access unit 41, thereby converting the medical image 17 into a monochrome image. Next, a labeling process is performed on the monochrome image. Then, the main part of the subject displayed in the medical image 17 is identified and extracted from other parts. Since a method of extracting the main part of the subject by binarization + labeling processing is well known, detailed description thereof is omitted. If necessary, "Determination of autonomous mobile robot behavior using visual sensors" Tomomitsu Yamaguchi et al. The Society of Instrument and Control Engineers Tohoku Branch 231st Research Meeting (2006.10.31) Document No. 231-4, JP2007- See, for example, Japanese Patent No. 299210.

  A plurality of tomographic images obtained by the CT apparatus and the MRI apparatus illustrated in FIG. 4 are obtained continuously in the body axis direction of the patient in one examination. For this reason, the region setting unit 42 performs binarization + labeling processing on a plurality of tomographic images related to one examination, and extracts a main part of each subject. The main part having the largest size is set as a main subject display area 60.

After extracting the main subject display area 60, the area setting unit 42 sets areas that are candidates for the incidental information display area 61 (hereinafter referred to as candidate areas). Specifically, the position of each pixel on the image display screen 46 shown in FIG. 4 is represented by XY coordinates (the upper left of the image display screen 46 is the origin (0, 0) and the lower right is the maximum value (X _MAX , Y _MAX ) ( For example, in the case of (X _MAX , Y _MAX ) = (1023, 767)), the lower limit of the Y coordinate of the main subject display area 60 is Y _LL (> 0), and (0 + α, 0 + β) and (X _MAX − A rectangle (width W ₀ = X _MAX −2α, height H ₀ = Y _LL −2β) with diagonal lines α and Y _LL −β is set as a candidate area. Assuming X _D1 and X _D2 , the widths W _{1 to} W ₃ of the sections 62 to 64 are W ₁ = X _D1 −α, W ₂ = X _D2 −X _D1 , W ₃ = X _MAX −X _D2 − It should be noted that α and β do not obscure the boundaries between the display areas 60 and 61. For example, 1 pixel.

Since one main subject display area 60 is extracted for a plurality of tomographic images related to one examination, the size is not constant for each examination, and Y _LL that is the lower limit of the Y coordinate changes. Therefore, the size of the candidate area (height H ₀ ) also changes for each examination. The area setting unit 42 outputs information (XY coordinate, width, height information) indicating the size of the main subject display area 60 and the candidate area to the console control unit 40 and the display form determination unit 43.

  First, the display form determination unit 43 uses the preset font metrics (layout information when displaying the font), and the supplementary information (order of the medical image 17) received from the DB access unit 41 or the order acquisition unit 45. When each item of the accompanying information is converted into a character string, the size of an area necessary for the display (hereinafter simply referred to as a necessary area, which is different from the candidate area) is calculated.

Here, the necessary area is an area necessary when the character string of the item having the accompanying information is displayed in one line without being folded. Since the content of the incidental information varies from inspection to inspection, the width of the necessary area also changes. However, according to the above definition, the height of the necessary area for one line is unchanged. As illustrated in FIG. 5, the display form determination unit 43 includes information on the size of the calculated necessary area (width w _i , height h _i (i = 1, 2, 3,..., M ₀ ; m ₀ is the total number of items to be displayed in the incidental information display area 61 (fourteen in this example)) is temporarily stored in the memory 32 in the data table format for each item of incidental information. In the following description, it is assumed that the font size of each item is the same (the height h _i is the same).

The display form determination unit 43 compares the width w _i of the necessary area of each item stored in the memory 32 with the size of the width W _{1 to} W ₃ of the corresponding section among the first to third sections 62 to 64. To do. When w _i is W _{1 to} W ₃ or less (w _i ≦ W _{1 to} W ₃ ) and each item fits within the width of the corresponding section, the display form determination unit 43 proceeds to height comparison. On the other hand, if w _i is larger than W _{1 to} W ₃ (w _i > W _{1 to} W ₃ ) and does not fit in the width of the corresponding section, the display form determination unit 43 sets the item in each section 62 to 64. It is decided to wrap and display at the end. The display form determination unit 43 doubles the height h _i of the necessary area stored in the memory 32 of the item determined to be folded and displayed by the amount of folding (twice in the case of one turn, double or double turn). In case of triple).

After comparing the widths as described above, the display form determination unit 43 multiplies the height h _i of the necessary area by the maximum number of rows in each section 62 to 64 (5 in this example), obtained by adding the line spacing of the string (hereinafter, referred to as MAXΣh _i) and is compared with the height H ₀ of the set candidate regions in the area setting unit 42. Incidentally, MAXshigumah _i are known for height h _i of the necessary area is unchanged regardless of the test differs from the width w _i, is stored in advance in the storage device 32.

When MAXΣh _i is equal to or lower than the height H ₀ (MAXΣh _i ≦ H ₀ ) and each item fits within the height of the candidate area, the display form determination unit 43 uses the default display form shown in FIG. Is determined to be displayed. In this case, the candidate area set by the area setting unit 42 becomes the incidental information display area 61 as it is.

On the other hand, when MAXΣh _i is larger than the height H ₀ (MAXΣh _i > H ₀ ) and each item does not fit in the height of the candidate area, the display form determination unit 43 is based on the attribute table 70 shown in FIG. The display form is determined.

  In FIG. 6, the attribute table 70 stores the attribute of each item of the incidental information in a data table format. The attribute indicates relevance as information of each item. When creating an interpretation or report 18, the same attributes are assigned to items that are desired to be viewed together. The attribute has a hierarchical structure, and has a first hierarchy and a second hierarchy. The second hierarchy is a further differentiation of the first hierarchy, and is a hierarchy below the first hierarchy. Three types of “patient-related”, “imaging-related”, and “image-related” are defined as attributes in the first layer, and one type of “basic” is defined as attributes in the second layer. Hereinafter, the attribute “patient-related” may be expressed as G11, “imaging-related” as G21, “image-related” as G31, and the attribute “basic” in the lower layers may be expressed as G12, G22, and G32, respectively.

  “Patient-related” includes items “patient name”, “patient ID”, “gender, date of birth”, and “height, weight”, among which “patient name” and “patient ID” are “ “Basic”, the rest is undefined. “Imaging related” includes the items “examination type”, “imaging date”, “imaging condition”, “imaging site”, “imaging time”, and “contrast agent”, of which “examination type” and “imaging date” The “shooting condition” is “basic” in the second layer, and is undefined afterward. “Image related” is the item “series number”, “number of pixels”, “window width”, and “window level”, of which “series number” and “number of pixels” are “basic” in the second layer, and Is undefined.

  In each attribute G11 to G31 of the first hierarchy, an area of the image display screen 46 (hereinafter referred to as a priority display area) on which items belonging to the attributes G11 to G31 are preferentially displayed is defined in advance. In each of the attributes G11 to G31, “first section”, “second section”, and “third section” are priority display areas. The attributes G12 to G32 of the second hierarchy follow the definition of the priority display area of the attributes G11 to G31 of the first hierarchy. The information on the priority display area is actually information (XY coordinate, width, height information) indicating the size of each section 62 to 64.

  The attribute may be set in advance and cannot be changed, or may be configured such that the interpretation doctor or the like can change the setting. The attribute may be set for each requesting doctor or interpretation doctor, or may be automatically changed depending on the type of lesion or examination type. In this example, the attributes are divided into the first and second hierarchies and defined as three types and one type, respectively, but there may be one or more hierarchies, and the type is not affected by this example.

  The display form determination unit 43 determines whether or not all items of the incidental information fit in the candidate region initially set by the region setting unit 42. If it is determined that all items do not fit, it is determined whether each item of the first layer fits in the candidate area. If it is determined that the items of the first hierarchy do not fit, it is further determined whether or not the items of the second hierarchy fit within the candidate area. If it is still determined that each item of the second hierarchy does not fit, a new candidate area is obtained for each item, and it is determined whether or not each item fits in the new candidate area.

That is, the processing of the display form determination unit 43 can be expressed as follows using symbols. The display form determination unit 43 selects m _n-1 items (≦ m ₀ items) having the same attribute in the ( _n−1 ) -th layer (n is a natural number of 1 or more) (all items when n = 1, all items). It is determined whether or not (item is defined as the 0th hierarchy) fits in the candidate area. If it is determined that the item does not fit in the candidate area, _mn (<m _n-1 and m _n-1 ) having the same attribute of the nth layer, which is a layer below the n-1th layer It is determined whether or not at least two of the items of the items fit in the candidate area. When it is determined that n is a preset upper limit and an item having the same attribute in the nth layer does not fit in the candidate area, the display form determination unit 43 determines whether each item fits in the candidate area. Determine whether or not.

  If it is determined that a certain item fits in the candidate area, at least a necessary area of the item among the candidate areas is assigned to the incidental information display area 61 of the item. If there is another item whose display form has not been determined, it is determined whether or not the other item fits in an area obtained by removing the amount assigned to the incidental information display area 61 from the candidate area.

Hereinafter, the process of the display form determination part 43 is demonstrated more concretely. When MAXΣh _i is larger than the height H ₀ , the display form determination unit 43 first determines the display form of the item of G11 in the first layer. Display type determining unit 43, the height h _i of the necessary area of each item stored in the memory 32, extracts the height h _i of the space required by the item of G11, the number of items of the height h _i of extracted G11 in the result of multiplying, obtained by adding the line spacing of the text of each item (hereinafter referred to as MID1Σh _i) is calculated. Then, comparing the MID1shigumah _i the calculated and the height _{H 0} of the set candidate regions in the area setting unit 42.

When MID1Σh _i of the item of G11 is equal to or lower than the height H ₀ (MID1Σh _i ≦ H ₀ ) and the item of G11 falls within the height of the candidate area, the display form determination unit 43 sets the priority display area of G11 to “first Since it is set to “compartment 62”, it is determined that the item G11 is displayed in the first compartment 62. In other words, the first section 62 is allocated to the incidental information display area 61 for the item of G11. In this case, the display form determination unit 43 proceeds to determination of the display form of the item of G21.

On the other hand, if MID1Σh _i of the item of G11 is larger than the height H ₀ (MID1Σh _i > H ₀ ) and the item of G11 does not fit in the height of the candidate area, the display form determination unit 43 displays the hierarchy below G11. The process proceeds to the determination of the display form of the item G12. Display type determining unit 43, the height h _i of the necessary area of each item stored in the memory 32, extracts the height h _i of the space required by the item of G12, the number of items of the height h _i of extracted G12 in the result of multiplying, obtained by adding the line spacing of the text of each item (hereinafter referred to as MID2Σh _i) is calculated. Then, comparing the MID2shigumah _i the calculated and the height _{H 0} of the set candidate regions in the area setting unit 42.

When MID2Σh _i of the item of G12 is equal to or less than the height H ₀ (MID2Σh _i ≦ H ₀ ), and the item of G12 falls within the height of the candidate area, the display form determination unit 43 places the item of G12 in the first section 62. Decide to display. In this case, the display form determination unit 43 proceeds to determination of display forms of the other items “Gender, Date of Birth” and “Height, Weight” of G11.

On the other hand, when MID2Σh _i of the item of G12 is larger than the height H ₀ (MID2Σh _i > H ₀ ) and the item of G12 does not fit in the height of the candidate area, the display form determination unit 43 sets one of the items of G11. It moves to the determination of each display form. The display form determination unit 43 extracts the height h _i of the required area of each item of G11 from the height h _i of the required area of each item stored in the memory 32. Then, the extracted h _i is compared with the height H ₀ of the candidate area set by the area setting unit 42.

When the height h _i of the required area of one item with G11 is equal to or less than the height H ₀ (h _i ≦ H ₀ ) and one item with G11 falls within the height of the candidate area, the display form determination unit 43 It is determined that one item with G11 is displayed in the first section 62.

On the other hand, if the height h _i of a necessary area of one item with G11 is larger than the height H ₀ (hi _i > H ₀ ) and one item with G11 does not fit within the height of the candidate area, the display form is determined. The unit 43 notifies the area setting unit 42 to that effect.

  In response to the notification from the display form determination unit 43, the region setting unit 42 searches for a region where one item with G11 can be displayed other than the candidate region set first. For example, the area setting unit 42 sets, as a new candidate area, an area that is as close as possible to the priority display area among the areas adjacent to or below the main subject display area 60. The area setting unit 42 outputs information on the size of the set new candidate area to the display form determining unit 43.

  Similarly to the above, the display form determination unit 43 compares the size of a necessary area for one item with G11 and the size of a newly set candidate area, and determines whether or not one item with G11 fits in the new candidate area. . When the size of the necessary area of one item with G11 is equal to or smaller than the size of the new candidate area and the one item with G11 fits in the new candidate area, the display form determination unit 43 newly sets one item with G11. To be displayed in a candidate area.

  On the other hand, if the size of the required area of one item with G11 is larger than the size of the new candidate area, and one item with G11 does not fit in the new candidate area, the display form determination unit 43 sets the one of the items with G11. Decide not to display the item. The display form determination unit 43 processes the other items of G11 in the same manner.

  After determining the display form of each item of G11, the display form determining unit 43 similarly determines the display form of each item of G21. At this time, the candidate area whose size is compared with the necessary area of each item of G21 is an area excluding the area determined to display the item of G11 (area allocated to the incidental information display area 61). Similarly, the display form determination unit 43 determines the display form of each item of G31. In the case of displaying in a section other than the default display form shown in FIG. 4, the width of paragraph [0069] is compared and it is determined again whether or not it is displayed, and then the height comparison is started.

  The display form determination unit 43 outputs the display form of each item of the incidental information determined as described above to the console control unit 40. The console control unit 40 performs display control of the display regions 60 and 61 based on commands from the region setting unit 42 and the display form determination unit 43.

  FIG. 7 shows a display form of the image display screen 46 different from the default display form of FIG. 4 that displays all items of the incidental information together. In the first section 62, the items of G11 are collectively displayed, and the item “inspection type” is not displayed unlike the example of FIG. In the second section 63, the items of G22 out of the items of G21 are collectively displayed, and the item “imaging region” is displayed. In the third section 64, items "imaging time" and "contrast medium" are displayed, and each item of G32 among the items of G31 is displayed together. A fourth section 67 is provided as a new area below the third section 64, and items “window width” and “window level” are displayed in the fourth section 67.

  In FIG. 7, for example, there are items that are not displayed in the priority display area, such as the items “imaging time” and “contrast agent”. In this example, since it is also possible to assign an item of an attribute to the priority display area of another attribute, there is no absolute binding force that the priority display area must be assigned to that area, and the display form is determined. When you do it, it's about assigning if it's free. There is no causal relationship between the priority display area and the candidate area, and the definition of the priority display area loses its effectiveness when the candidate area cannot be taken at the location defined in the priority display area. When an item with a certain attribute invades a priority display area with another attribute, a new candidate area may be set and an item may be assigned to the new candidate area.

  In FIG. 3, the console control unit 40 receives an input of a finding sentence in the finding sentence input area 48 of the report editing screen 47 and instructs the editing processing unit 44 to execute a process according to the operation instruction. To do.

  The edit processing unit 44 receives the finding data input to the finding sentence input area 48 through the console control unit 40. The edit processing unit 44 discriminates the received finding data for each finding sentence input area 48.

  The edit processing unit 44 adds the finding IDs such as “F-1” and “F-2” to each of the blocked finding data, and records these in the data of the report 18. The edit processing unit 44 adds information such as examination ID, patient ID, and patient name read from the order to the data of the report 18 in addition to the finding data.

  In addition to the finding ID, the editing processing unit 44 adds, to each finding data, a doctor ID for identifying the interpretation doctor who has input the finding sentence. The doctor ID is input by the interpretation doctor at the time of user authentication when the report creation terminal 13 is activated. The finding data can be searched by finding ID or doctor ID.

  The order acquisition unit 45 acquires an order from the order reception terminal via the network 15. The acquired order is registered in an order table (not shown) provided in the storage device 32 of the report creation terminal 13, for example.

  The CPU 30 of the DB server 14 functions as a storage processing unit 50 and a search processing unit 51 for the data of the medical chart 16, the medical image 17, and the report 18 by executing the server program. The storage processing unit 50 executes data storage processing in each of the DBs 19 to 21 in response to a data storage request from a client such as the report creation terminal 13 or the modality 22. In response to the data distribution request from the department terminal 11 and the report creation terminal 13, the search processing unit 51 searches the DBs 19 to 21 for the requested data and distributes the searched data to the request source. .

  Hereinafter, the operation of the above configuration will be described with reference to the flowcharts shown in FIGS. The requesting doctor uses the clinical department terminal 11 to issue an order. The report creation terminal 13 receives the order issued from the clinical department terminal 11 via the order reception terminal of the examination department 12.

  The interpretation doctor confirms the order at the report creation terminal 13 and starts creating the report 18. When the report edit screen 47 is displayed on the display 37b, the image display screen 46 is displayed on the display 37a in conjunction with this.

  In step (hereinafter abbreviated as S) 10 in FIG. 8, prior to displaying the image display screen 46, the main subject display area 60 and candidate areas are set by the area setting unit 42. First, binarization processing is performed on the data of the medical image 17 received from the DB access unit 41 by the region setting unit 42. Next, a labeling process is performed on the black and white image generated by the binarization process, and the main part of the subject displayed on the medical image 17 is extracted. Thereby, the main subject display area 60 is extracted.

  After extracting the main subject display area 60, the area setting unit 42 sets candidate areas. Information representing the size of the main subject display area 60 and the candidate area set by the area setting unit 42 is output to the console control unit 40 and the display form determination unit 43.

  In S11, the display form determination unit 43 calculates the size of the necessary area. The information on the size of the necessary area calculated by the display form determination unit 43 is temporarily stored in the memory 32 in the data table format for each item of the supplementary information.

In S12, the display form determination unit 43 compares the width w _i of the necessary area of each item with the sizes of the widths W _{1 to} W ₃ of the sections 62 to 64, and determines an item to be displayed in a folded manner. When w _i is larger than W _{1 to} W ₃ (w _i > W _{1 to} W ₃ ), it is determined that the item is folded and displayed. The height h _i of the necessary area of the item determined to be folded and displayed is multiplied by the folded amount.

In S13, the height h _i of the necessary area to the result of multiplying the maximum number of rows in each compartment 62 to 64, and MAXshigumah _i obtained by adding the line spacing of the text of each item, candidates set by the area setting unit 42 regions of the height H ₀ is compared.

If MAXΣh _i is equal to or lower than the height H ₀ (Σh _i ≦ H ₀ ) (yes in S14), it is determined that all items are displayed together in the candidate area (S15). On the other hand, if MAXΣh _i is larger than the height H ₀ (Σh _i > H ₀ ) (no in S14), the process proceeds to display mode determination based on the attribute table 70 in S16.

9 showing details of the processing of S16, the display type determining unit 43, MID1Σh _i item attribute of the first hierarchy is calculated. Then, the calculated MID1Σh _i is compared with the height H ₀ of the candidate area set by the area setting unit 42 (S20).

When MID1Σh _i of the attribute item of the first hierarchy is less than or equal to height H ₀ (MID1Σh _i ≦ H ₀ ) (yes in S21), the area (priority display) set as the priority display area among the candidate areas When the area is not empty, it is determined to display the attribute item of the first hierarchy in another area (S22). On the other hand, when MID1Σh _i is larger than the height H ₀ (MID1Σh _i > H ₀ ) (no in S21), the process proceeds to the determination of the display form of the attribute item in the second layer in S23.

10 showing details of the processing of S23, the display type determining unit 43, MID2Σh _i item attribute of the second hierarchy is calculated. Then, a MID2shigumah _i calculated, the height _{H 0} of the set candidate regions in the area setting unit 42 are compared (S30).

When MID2Σh _i of the attribute item of the second hierarchy is less than or equal to height H ₀ (MID2Σh _i ≦ H ₀ ) (yes in S31), the area (priority display) set as the priority display area among the candidate areas If the area is not empty, it is determined that the attribute item of the second hierarchy is displayed in another area (S32). On the other hand, if MID2Σh _i is larger than the height H ₀ (MID2Σh _i > H ₀ ) (no in S31), a new candidate area is created in the area setting unit 42 for each item of the attribute of the second hierarchy. Is set and the display form is determined (S33).

  Returning to FIG. 9, if the display form of all items has not been determined (no in S24), the area assigned to the incidental information display area 61 is removed from the candidate area (S25), and the process returns to S20. . If the display form of all items is determined (yes in S24), the process returns to FIG.

  In FIG. 8, after the display forms of all items are determined by the display form determination unit 43, the console control unit 40 is based on the information set by the area setting unit 42 and the information determined by the display form determination unit 43. Thus, display control of the display areas 60 and 61 is performed, and the image display screen 46 is activated (S17).

  The interpretation doctor inputs a finding sentence in the finding sentence input area 48 of the report editing screen 47 while observing the medical image 17 on the image display screen 46. When the observation text is input, the observation data is transferred from the console control unit 40 to the editing processing unit 44.

  The finding data is divided into blocks for each finding sentence input area 48 by the editing processing unit 44, and the finding ID is added and recorded in the data of the report 18. In addition to the finding data, data of the examination ID, patient ID, patient name, doctor ID, and the like are added to the data of the report 18.

  When the interpretation doctor finishes inputting the finding sentence, it instructs the end of creation of the report 18. When the creation end is instructed, a data storage request for the report 18 is transmitted from the DB access unit 41 to the DB server 14. When the storage request is received from the report creation terminal 13, in the DB server 14, the storage processing unit 50 executes the storage processing for the data of the report 18. This completes the process of creating a single report 18.

  When the creation of the report 18 is completed, a report of completion of creation is transmitted from the report creation terminal 13 to the medical department terminal 11 of the requesting doctor. The requesting doctor accesses the report DB 21 through the medical department terminal 11 and reads the report 18 based on the address of the report 18 included in the creation completion notification. The display 37 of the medical department terminal 11 outputs a report display screen and an image display screen for displaying the medical image 17 related to the report 18. The requesting doctor browses these screens and confirms the contents of the report 18.

  As described above, the display form is determined so as to display the items related to each other as much as possible without moving or reducing the medical image 17, so that the report quality of the medical image 17 is not impaired. 18 can be made more smoothly.

  Since the area setting unit 42 automatically extracts the main subject display area 60 and sets the incidental information display area 61, it is possible to save the trouble of manually setting the display areas 60 and 61.

In the above-described embodiment, the maximum number of lines in each of the partitions 62 to 64 is defined. However, when MAXΣh _i ≦ H ₀ , items exceeding the maximum number of lines may be displayed.

  In the above embodiment, binarization and labeling processing is performed on a plurality of tomographic images related to one examination, and the main part of each subject is extracted, and the main part having the maximum size is extracted. Although the main subject display area 60 is used, the main subject display area 60 may be extracted for each of a plurality of tomographic images. Further, when the size of the main subject display area 60 is unchanged, such as when the medical image 17 is an endoscopic image or an ultrasonic image, the area setting unit 42 is not necessary. Further, gray scale processing may be performed instead of binarization processing.

  In the above embodiment, the display form of the G11 item is first determined and then the display form of the G21 and G31 items is sequentially determined. However, the order of determining the display form is not particularly limited. The attribute items that can be accommodated in the candidate area may be found out of order, and the incidental information display area may be assigned first from the attribute item that has been determined to fit in the candidate area.

  For example, when it is determined that the item of G11 does not fit in the candidate area, it is determined whether or not the item of G21 fits in the candidate area without moving to determining the display form of the item of G12. If it is determined that the item of G21 fits in the candidate area, the supplementary information display area 61 is assigned first.

  If the size of the main subject display area 60 is too large and the candidate area cannot secure a desired area and there is an item determined not to be displayed by the display form determination unit 43, the medical image 17 cannot be avoided. May be reduced.

  In the above embodiment, when a report is created by a report creation terminal, the display form of the incidental information display area is determined. However, when a medical image is browsed together with a report that has been created on the medical department terminal, The display form of the incidental information display area may be determined. In this case, if the information of the display form of the incidental information display area determined by the display form determination unit of the report creation terminal is stored in association with the data of the medical image by the DB access unit, the medical image data is stored at the medical department terminal. When is opened, a medical image can be displayed in the same display form as the display form on the image display screen of the report creation terminal. Of course, each unit 40 to 43 of FIG. 3 may be provided in the medical department terminal, and the medical department terminal may be used as the medical image display device of the present invention.

  In the above-described embodiment, the examination performed by the examination department 12 is described as an example. However, the examination type is not limited to these, and a PET (Positron Emission Tomography) examination, an ultrasonic examination, an endoscopic examination, and the like. But you can.

  In the above-described embodiment, an example of a single report creation terminal that constitutes the medical image display apparatus of the present invention has been described. However, a plurality of report creation terminals may be used. Moreover, although the aspect which stores an attribute table in the storage device of a report creation terminal was illustrated, the storage destination of an attribute table is not restricted above, You may store in DB server. In this case, the DB access unit of the report creation terminal accesses the DB server to transmit the attribute table search request and receive the search result.

  In the case of a client server type information system comprising a client (report creation terminal) and a server (DB server) as in the above embodiment, a dedicated program is used as a client program for report editing. Alternatively, a general-purpose browser corresponding to a WWW (World Wide Web) protocol such as HTTP (Hyper Text Transfer Protocol) may be used.

  When a dedicated program is used, the report edit screen is generated based on screen data defined by the dedicated program. When a general-purpose browser is used, for example, the report edit screen data is stored in the Web server, and the client accesses the Web server and stores the report edit screen data processed into the Web page format. to download. The client browser interprets the source code of the received Web page and generates a report editing screen. The Web server may be shared by the DB server 14 or may be a server different from the DB server. When a general-purpose browser is used, the CPU of the Web server configures a console control unit, an editing processing unit, or the like in cooperation with the CPU of the client or independently.

  The data storage device in which the DB is constructed may be other than the DB server, and for example, a storage device connected via a network such as NAS (Network Attached Storage) or SAN (Storage Area Network) may be used. Thus, the physical configuration of the computer system can be changed as appropriate.

  In the above embodiment, the LAN is described as an example of the network. However, when the clinical department and the examination department are distributed at a plurality of bases, a combination of the LAN and the WAN (Wide Area Network) is used as the network. May be used.

  As described in the above embodiment, the present invention naturally extends to a program form and further to a storage medium for storing the program.
