Description

  The present invention relates to a medical image display device and a program.

In the medical field, digitization of medical images obtained by examination imaging such as X-ray imaging and CT (Computed Tomography) imaging has progressed, and doctors interpret images using medical images displayed on a display.
At the time of interpretation, a doctor sometimes draws an auxiliary line or marks a medical image and measures the distance and angle between tissues. In order to assist such a doctor's work, an apparatus capable of drawing and measuring a displayed medical image has been developed.

After interpretation, the doctor creates a report about interpretation, and a medical image may be attached to the report. However, in CT imaging and MRI (Magnetic Resonance Imaging) imaging, the number of medical images obtained in one examination is 100 to 1000, and the number of medical images to be read is very large. It is very complicated to find a medical image that a doctor wanted to attach at the time of interpretation from a large number of medical images. Thus, a method is disclosed in which a medical image to be referred to when creating a report later can be bookmark-registered by a doctor's registration operation while displaying a medical image for interpretation (see, for example, Patent Document 1).

  According to the present invention, a drawn medical image can be easily displayed from among a plurality of medical images.

  Embodiments of the present invention will be described below with reference to the drawings.

  FIG. 1 is a diagram showing a configuration of a medical image system 1. As shown in FIG. 1, the medical image system 1 includes a server 10 and a medical image display device 20 according to the present embodiment. The server 10 and the medical image display apparatus 20 can communicate with each other via the network N. As the communication method, DICOM (Digital Imaging and Communication in Medicine) generally used as a communication method for medical images can be cited.

  The server 10 stores and manages medical images, electronic medical records, and reports. In response to a request from the medical image display device 20, the server 10 transmits and provides a medical image, an electronic medical record, and a report to the medical image display device 20.

  The medical image display device 20 acquires a medical image from the server 10 and displays it. In addition, the medical image display device 20 creates an electronic medical record and a report according to the operation of the doctor, and transmits the electronic medical record and report to the server 10.

FIG. 2 shows a functional configuration of the medical image display apparatus 20.
As shown in FIG. 2, the medical image display device 20 includes a control unit 21, a storage unit 22, a display unit 23, an operation unit 24, a communication unit 25, an I / F unit 26, and a CD / DVD drive 27.

The control unit 21 is a control unit including a CPU (Central Processing Unit), a RAM (Random Access Memory), and the like. The control unit 21 performs various calculations in cooperation with the program stored in the storage unit 22, controls the operation of each unit, and executes processing.
For example, the control unit 21 displays a plurality of medical images for one series on the viewer screen. When the drawing operation is performed on the medical image displayed on the display unit 23, the control unit 21 draws the medical image on the medical image according to the operation, and identification information indicating that the medical image is drawn. Is stored in the storage unit 22. In addition, when the display of the drawn medical image is instructed, the control unit 21 extracts the drawn medical image from the plurality of medical images for one series based on the identification information stored in the storage unit 22. To be displayed on the display unit 23.

The storage unit 22 is composed of, for example, a hard disk, and stores parameters and files necessary for execution of processing in addition to various programs.
The storage unit 22 stores medical images to be displayed, created electronic medical records, and report files.

The storage unit 22 is a storage unit that stores a drawing table. The drawing table is a table in which identification information indicating that a medical image has been drawn is set.
FIG. 3 shows an example of a drawing table. The drawing table T1 shown in FIG. 3 stores a medical image series management number, an image management number, a flag indicating the type of drawing, and a flag indicating a group to which the type belongs in association with each other. ing.

  When a plurality of medical images are obtained by one unit of examination imaging, such as MRI imaging or CT imaging, the plurality of medical images are handled as the same series of medical images, and are managed by being assigned the same series number. . For example, in the case of CT imaging for obtaining a plurality of tomographic images from the chest to the abdomen, the plurality of tomographic images are all assigned the same series number. However, when a plurality of examinations are included in one examination, for example, a series with the same series number 1 exists in a certain examination A and a certain examination B, and the series number itself is not a unique number. Therefore, in order to manage each series uniquely, a unique series management number is assigned to each series. That is, the series management number of the medical image indicates that the medical image having the same series management number is obtained by the same examination.

  In addition to the series number, an image number is assigned to identify individual medical images in the series. Image numbers are assigned in the order in which a plurality of medical images of one series are generated by photographing. For example, in the case of CT imaging of a tomographic image from the chest to the abdomen, the first tomographic image generated on the chest side is the head, the tomographic image generated on the abdomen side is the tail, and the images are in the order of 1, 2, 3,. A number is given. However, there are cases where the same number exists in another series, and it is not a unique number in a system having a plurality of series. Therefore, a unique image management number is assigned to each medical image in order to uniquely manage each medical image.

  The drawing type flag is identification information indicating that a medical image has been drawn and what kind of drawing has been performed. The medical image display apparatus 20 can perform a plurality of types of drawing, and can draw various types of graphics such as dots, lines, rectangles, ellipses, and arrows as shown in FIG. It is also possible to draw a measurement value such as a distance and an angle measured by the control unit 21 with drawing of a figure. Therefore, a flag indicating the type is assigned to each type of drawing. For example, a flag “1” is assigned for point drawing, a flag “2” is assigned for straight line drawing, and a flag “3” is assigned for ellipse drawing. Also, the drawing of the distance of the straight line is “11” flag, and the drawing of the angle at the intersection of two straight lines (called the three-point angle) is “12”, the angle of the intersection of the two straight lines on the extension line ( In the case of drawing (called a hump angle), a flag “13” is assigned.

  The types of drawing are grouped. The drawing type group flag is identification information indicating in which group the drawing applied to the medical image is classified. For example, as shown in FIG. 4, the group may be classified into a graphic group for drawing a graphic and a measurement system group for drawing a measurement value. Moreover, it may be classified by the type unit often used for each medical field such as radiology, nuclear medicine, orthopedics, or for each department such as internal medicine, surgery, orthopedics, and radiology. May be classified. It is not necessary to classify all the drawing types. In addition, the user can set which group to classify.

  For example, when grouping by medical field, as a radiological group, straight line, rectangle, ellipse, polygon drawing, maximum pixel value, minimum pixel value, average pixel value, standard calculated in these figures Drawings of measurement values such as deviations can be classified, and a group flag “1” is assigned to these drawing types. In addition, as a group of nuclear medicine, drawing of rectangles, ellipses, polygons, maximum values of SUV (Standardized Uptake Value) calculated within these figures, average values, standard deviations, etc. Measurement value drawing can be classified, and a group flag “2” is assigned to these drawing types. Drawings of measurement values such as sharp angles, femoral neck angles, and baler angles can be classified as orthopedic groups, and a group flag “3” is assigned to these drawing types.

  The storage unit 22 stores a key image table. The key image table is a table in which information indicating that a medical image is designated as a key image is set. The key image refers to a medical image designated by a doctor as a medical image to be noticed by the doctor. For example, a medical image that a doctor wants to attach to a report and a medical image that the doctor wants to refer to later are listed.

  FIG. 5 shows an example of the key image table. In the key image table T2 shown in FIG. 5, for the medical image specified as the key image, the series management number of the medical image, the image management number, and the user ID assigned to the user (doctor) who performed the specification correspond to the key image table T2. It is remembered.

The display unit 23 is display means provided with a display. The display unit 23 displays various display screens such as a viewer screen for displaying a medical image for interpretation and a report screen for report input according to display control of the control unit 21.
The operation unit 24 includes a mouse and a keyboard, generates operation signals corresponding to these operations, and outputs them to the control unit 21. The operation unit 24 may be a touch panel integrated with the display of the display unit 23.

  The communication unit 25 includes a communication interface, and performs communication with an external device such as the server 10 according to communication control of the control unit 21. For example, the communication unit 25 transmits medical image request information to the server 10 and receives a medical image from the server 10.

The I / F unit 26 is connected to the CD / DVD drive 27 and exchanges data with the CD / DVD drive 27.
The CD / DVD drive 27 reads / writes data from / to the medium M. The medium M is a CD or a DVD. For example, the CD / DVD drive 27 reads past medical images and reports recorded on the medium M, and writes the medical images and reports newly obtained in the current examination. Examples of such data standards include PDI (Portable Data for Imaging).

Next, processing executed by the medical image display device 20 will be described.
When interpreting a medical image, the doctor can operate the medical image display device 20 to display the medical image on the viewer screen.
FIG. 6 shows a flow of processing executed by the medical image display device 20 when a doctor interprets a medical image. Prior to this processing, it is assumed that one series of medical images obtained by CT imaging is acquired from the server 10 as an interpretation target and stored in the storage unit 22.

  As shown in FIG. 6, in the medical image display device 20, the control unit 21 displays a viewer screen on the display unit 23, and a plurality of medical images for one series are displayed in a stack on the viewer screen (step S1). Stack display refers to a display form in which one medical image is displayed in one frame and a plurality of medical images are sequentially displayed while switching the medical images displayed in the frame. The doctor can interpret one series of medical images one by one on the stack display.

FIG. 7 shows an example of a viewer screen on which medical images are stacked.
As shown in FIG. 7, one frame is displayed on the entire screen by stack display, and one medical image is displayed in this frame. On the medical image, the series management number and the image management number information d1 of the medical image are displayed. A slider bar d2 is displayed on the medical image. The slider bar d2 indicates the number of all medical images corresponding to one series. “15” of “15/107” displayed on the slider bar d2 indicates the order of medical images currently displayed on the viewer screen, and “107” indicates the number of all medical images for one series.

  A button d21 on the slider bar d2 represents the position of the medical image currently displayed in the series. The button d21 is the currently displayed medical image when one series of medical images is arranged in the order of the image management number, with the upper end of the slider bar d2 being the image management number 101 corresponding to the head of the series and the lower end being the last image management number 207. It is arranged at a position corresponding to the image management number 115 of the image. When the position of the button d21 is moved by the scroll operation, the medical image currently displayed on the viewer screen is switched to the medical image having the image management number corresponding to the position where the button d21 is moved.

  The doctor can perform a drawing operation on the medical image currently displayed on the viewer screen. The doctor sequentially interprets one series of medical images using a stack display, and performs a drawing operation on medical images that require drawing and measurement. For the drawing operation, a drawing tool d31 shown in FIG. 7 is used. Since the drawing type is selectively displayed on the drawing tool d31, the doctor performs an operation of selecting a desired drawing type. For example, if straight line drawing is selected, the doctor further performs a selection operation of the start point and the end point on the medical image by operating the mouse. In response to such a drawing operation, the control unit 21 displays a straight line connecting the start point and the end point on the medical image. If drawing of the measurement value of the straight line distance is selected by the drawing tool d31, the control unit 21 draws the straight line, calculates the distance of the straight line, and calculates the calculated measurement value of the distance on the medical image. Draw near a straight line.

  In addition, the doctor can designate a medical image currently displayed on the viewer screen as a key image. As shown in FIG. 7, the viewer screen is provided with a key image button d4 for designating as a key image. Therefore, if the medical image currently displayed is considered to be attached when the report is created, the doctor The image button d4 may be operated.

  In such a viewer screen, the control unit 21 determines whether or not a drawing operation has been performed on the currently displayed medical image (step S2). When a drawing operation is performed (step S2; Y), the control unit 21 performs drawing on the medical image in accordance with the drawing operation as described above, and the type and group of the drawing performed on the medical image. Set the flag. For example, when a straight line is drawn, the flag “2” indicating the type of straight line is set, and the flag “1” of the group to which the straight line type belongs is set. The control unit 21 writes and stores the series management number, image management number, set drawing type, and group flag of the drawn medical image in the drawing table T1 (step S3).

  Although the drawing operation is not performed (step S2; N), when the designation operation as the key image is performed by the operation of the key image button d4 (step S4; Y), the control unit 21 indicates that the currently displayed medical image is the key. As information indicating that the image has been designated, the series management number and image management number of the medical image and the user ID of the designated doctor are written and stored in the key image table T2 (step S5). The doctor's user ID is input for user authentication at the time of login to the medical image display device 20, and therefore the user ID input at the time of login may be used.

  Next, the control unit 21 determines whether or not an interpretation end operation has been performed (step S6). When an operation for ending the interpretation is performed (step S6; Y), the present process is terminated. When an operation for ending the interpretation is not performed (step S6; N), the process returns to the process of step S2. That is, while sequentially interpreting one series of medical images, if there is a drawing operation by a doctor, a drawing type and a group flag are stored, and if there is a key image designation operation, it indicates that it has been designated as a key image. Information is stored.

After interpretation of the medical image displayed by the above-described processing, the doctor can display a report screen, perform a report input operation on the report screen, and create a report. When creating a report, medical images can be displayed again on the viewer screen if necessary.
FIG. 8 shows the flow of processing executed by the medical image display device 20 when displaying a medical image when creating a report.

  As shown in FIG. 8, the medical image display device 20 displays a report screen on the display unit 23 by the display control of the control unit 21. The report screen is an operation screen for report input. Moreover, according to a doctor's instruction | indication, the control part 21 displays a viewer screen so that it may overlap with a report screen (step S21).

  On the viewer screen, a series of medical images designated by a doctor can be displayed in a stack in the order of image management numbers as usual, or only drawn medical images can be displayed in a stack. For example, the Tab key on the keyboard of the operation unit 24 is assigned to a key for instructing to display only the drawn medical image.

  When the doctor operates the Tab key to instruct the display of the drawn medical image (step S22; Y), the control unit 21 corresponds to the series management number of the series designated to be displayed on the viewer screen by the doctor. Thus, the image management number of the medical image for which the drawing type flag is set in the drawing table T1 is specified. Then, the control unit 21 extracts a medical image having the specified image management number from a plurality of medical images for one series stored in the storage unit 22, and displays the medical image with a stack on the viewer screen (step S23).

  The extracted medical images are displayed in a stack in the order of image management numbers, and switching of image management numbers can be instructed by operating the Tab key. That is, when the Tab key is further operated in a state where the medical images having the smallest image management number among the drawn medical images are displayed in a stacked manner (step S24; Y), the control unit 21 displays the medical image currently being displayed. The image is switched to the medical image of the next image management number among the drawn medical images and displayed (step S25). In particular, if there is no operation of the Tab key (step S24; N), this process is terminated.

FIG. 9 shows a display transition example of the drawn medical image when the medical images having the image management numbers 115, 149, and 152 are drawn in one series.
Regardless of whether or not the viewer screen is initially drawn, the first medical image having the image management number 101 among the plurality of medical images of one series is displayed in the frame on the viewer screen. Here, when the Tab key is operated by the doctor, the display is switched from the display of the medical image with the image management number 101 to the display of the medical image with the image management number 115 drawn. By further operation of the Tab key, the image management number 115 is sequentially switched to the medical image drawn with the image management number 149, and the image management number 149 is switched to the medical image drawn with the image management number 152.

  Thus, every time the Tab key is operated on the viewer screen, the drawn medical images are displayed one after another in the order of image management numbers. As shown in FIG. 9, the key function may be assigned so that medical images drawn in the reverse order of the image management number order are displayed by simultaneous operation of the Tab key and the Shift key.

  In addition, the drawn medical image may be displayed in units of drawing types or groups of types. In this case, the control unit 21 causes the display unit 23 to display a drawing type or group selection screen when the Tab key is operated on the viewer screen. For example, type selection candidates such as straight lines, rectangles, ellipses, distances, and angles are displayed on the selection screen for types, and group selection candidates for groups such as radiology and nuclear medicine. Is displayed. When the type or group is selected by the doctor, the control unit 21 specifies the image management number of the medical image in which the drawing type or group flag selected in the drawing table T1 is set. Then, the control unit 21 extracts the medical image having the specified image management number from the storage unit 22 and displays it on the viewer screen. Even after a type or group is selected once, the type or group can be reselected in the middle.

For example, when a rectangular type is selected, medical images for which a rectangular type flag is set in the drawing table T1 are extracted from the storage unit 22 and displayed in a stack in the order of image management numbers. In the example shown in FIG. 9, medical images are stacked and displayed in the order of image management number 101 → image management number 149 by operating the Tab key.
When a nuclear medicine group is selected, medical images in which the nuclear medicine group flag is set in the drawing table T1 are extracted from the storage unit 22 and displayed in a stack in the order of image management numbers. In the example shown in FIG. 9, medical images are stacked and displayed in the order of image management number 101 → image management number 149 → image management number 152 by operating the Tab key.

  In addition, when referring to the medical images before and after the drawn medical image, the doctor may operate the cursor key in a state where the drawn medical image is displayed. In response to the operation of the cursor key, the control unit 21 switches to and displays the previous image management number or the next image management number medical image of the drawn medical image.

The above is the flow of processing when only the drawn medical image is displayed, but it may be configured to display not only the drawn medical image but also the key image. A key image can be referred to together with the drawn medical image.
For example, the Tab key is assigned as a key for instructing to display the drawn medical image and the key image. When the Tab key is operated in step S22 of FIG. 8, the control unit 21 is stored in the storage unit 22. From the medical images for one series, a medical image for which a flag for a drawing type is set in the drawing table T1 and a medical image for which information indicating a key image is set in the key image table T2 are extracted. To do. In steps S23 to S25, when the Tab key is operated, the extracted medical images are displayed in a stack in the order of image management numbers.

That is, by operating the Tab key, the medical image drawn on the viewer screen and the medical image designated as the key image are sequentially displayed in the order of image management numbers.
For example, when a medical image with image management numbers 107 and 136 is designated as a key image among a plurality of medical images in one series and a medical image with image management numbers 115 and 149 is drawn, as shown in FIG. The medical images displayed in the order of the image management numbers 107, 115, 136, and 149 change according to the key operation. At this time, the display order may be traced back in the reverse order by simultaneous operation of the Tab key and the Shift key.

  As described above, according to the present embodiment, a plurality of medical images for one series are displayed on the display unit 23 at the time of interpretation, and when the drawing operation is performed on the displayed medical images, the control unit 21 A drawing type flag indicating that the medical image has been drawn is stored in the drawing table T1 of the storage unit 22. Thereafter, when a display of a medical image drawn by the operation of the Tab key is instructed at the time of creating a report or the like, the control unit 21 makes a plurality of data for one series based on the drawing type flag stored in the drawing table T1. The drawn medical image is extracted from the medical images and displayed on the display unit 23.

Thereby, the drawn medical image can be easily displayed after drawing. After the interpretation, the doctor can call the medical image drawn at the time of the interpretation with a simple operation, and the labor of searching the drawn medical image from a large number of medical images in one series can be saved. In particular, in the display mode in which the medical images are displayed in a stack, after the drawn medical images are displayed, the medical images around the drawn medical images can be easily displayed if necessary. It is.
In addition, since the drawing type flag is stored in the storage unit 22 at the timing when drawing operation is performed on the medical image, the doctor designates the drawn medical image as a key image one by one so that the drawn medical image can be called later. There is no need to perform the operation, and the work burden on the doctor can be reduced. Since the number of times of drawing is larger than the designation of the key image, a configuration in which such a designation operation is omitted is particularly effective.

  Further, when the doctor instructs the display of the medical image drawn by selecting the drawing type, the control unit 21 makes a plurality of data for one series based on the drawing type flag stored in the drawing table T1. Among the medical images, the medical image on which the selected type is drawn is extracted and displayed on the display unit 23. Thereby, even when there are a large number of drawn medical images, the doctor can refer to the drawn medical images limited to the type of drawing to be referred to. Since many types of drawing are prepared, displaying a limited type makes it easy to search for a target medical image.

  Further, when a drawing operation is performed, the control unit 21 stores a flag indicating a drawing type group in the drawing table T1. When a doctor selects a drawing type group to display a drawn medical image, the control unit 21 controls a plurality of medical images for one series based on the stored drawing type group flag. Among them, a medical image on which a type belonging to the selected group is drawn is extracted and displayed on the display unit 23. Thereby, even when there are a lot of drawn medical images, the doctor can refer to the drawn medical images only for drawing of the group to be referred to. Since many types of drawing are prepared, it is easy to search for a target medical image by displaying only for groups in which frequently used types are classified.

In addition, the said embodiment is a suitable example of this invention, and is not limited to this.
For example, FIG. 7 shows an example in which one frame is displayed on the entire viewer screen, and a plurality of medical images for one series are displayed in a stack in this frame. However, in addition to this, two frames are displayed on one screen, series A is displayed in one frame, series B is displayed in the other frame, and the medical images of each series A and B are synchronized. There are cases where it is operated. In this way, when the medical image is displayed by a plurality of frames, the present invention is applied, and only the medical image drawn in each of the series A and B may be extracted and displayed.
Furthermore, the present invention is not limited to displaying a plurality of medical images for one series, and a plurality of different series of medical images may be displayed. Also in this case, by applying the present invention and specifying the drawing type flag from the series management number and image management number of the medical image to be displayed, only the drawn medical image can be extracted and displayed.

  Moreover, although the said embodiment demonstrated the example in case a doctor refers to a medical image by stack display, this invention is applicable also when displaying by tile display. Tile display refers to a display form in which one frame is divided into a plurality of areas and a medical image is displayed in each of the divided areas. Specifically, when display of the medical image drawn in step S22 of FIG. 8 is instructed, in step S23, the control unit 21 extracts the medical image in which the drawing type flag is set. The control unit 21 tiles the extracted medical images in the order of image management numbers as shown in FIG. Accordingly, even in a display form in which a series of medical images is displayed as a list by tile display, the doctor can easily refer to only the drawn medical images.

When a plurality of displays are used, the following display may be performed.
For example, when three displays can be used as shown in FIG. 12, a report screen A1, a viewer screen A2 that displays a series of medical images in a stack, and a viewer screen A3 that displays only the drawn medical images are displayed on each display. To do. When a doctor performs a report input operation on the report screen A1 and wants to refer to the drawn medical image in more detail, the medical image to be referred to may be selected from the tiled medical images on the viewer screen A3. The control unit 21 switches the displayed medical image currently displayed on the viewer screen A2 to the drawn medical image selected on the viewer screen A3.

  In this way, using the tile display as a table of contents when the doctor selects medical images to be displayed in a stack, the doctor's report creation becomes more efficient. In the tile display, only the drawn medical images are displayed, but in the stack display, it is easy to display the medical images before and after the drawn medical images. When a plurality of displays can be used, it is effective in that each display can display according to the purpose.

  In the above-described embodiment, the medical image display device 20 is configured to process alone, but may be processed by a client / server configuration. In the client / server configuration, the server 10 manages the drawing table T1 and the key image table T2, and when the medical image display device 20 performs a drawing operation or a key image designation operation, information to be written in the drawing table T1 and the key image table T2 is stored. Upload to the server 10. When the medical image drawn on the medical image display device 20 is displayed, the drawing table T1 and the key image table T2 downloaded from the server 10 are used.
