Description

  The present invention relates to a medical image diagnostic apparatus capable of easily laying out a plurality of series of medical images, a control method thereof, and a program.

  Interpretation of medical images taken with various modalities such as an X-ray CT apparatus and an MRI apparatus is performed by an interpreting doctor who specializes in interpretation. However, interpretation doctors are not at all medical institutions. Therefore, a medical institution without an interpreting doctor requests an interpretation from the interpretation center that undertakes the interpretation.

  When an image interpretation doctor performs an image interpretation, a viewer for browsing a medical image is used. The viewer can display a plurality of series of medical images side by side in an arbitrary layout.

  As a technique for performing such a medical image layout (what kind of medical image is arranged at what place), there is a so-called hanging protocol. The hanging protocol is to arrange the layout of medical images according to a preset pattern. Since the layout pattern of the medical image can be set for each purpose of interpretation, there is no need for the interpreting doctor to perform layout again each time the medical image is displayed, leading to improvement in interpretation efficiency. Patent Document 1 discloses a mechanism related to machine learning of such a hanging protocol.

JP 2013-106951 A

  However, the hanging protocol has a problem that it is necessary to set in advance a pattern as to when and what layout to use, using information such as the type of modality that generated the medical image and the examination site. There are many different purposes for interpretation by the interpreting doctor, and it is very troublesome for the interpreting doctor to register all these patterns in advance.

  In addition, in order to display a plurality of series of medical images, all series of medical images may not be displayed unless the display area is scrolled. If a medical image is displayed outside the display area, it may be overlooked even though it is a medical image to be interpreted. Therefore, all series of medical images to be displayed must be laid out so as to fit within the display area.

  An object of the present invention is to provide a mechanism capable of easily laying out a plurality of series of medical images.

  In order to achieve the above object, the medical image diagnostic apparatus of the present invention is a medical image diagnostic apparatus capable of displaying a plurality of series of medical images, the selection receiving means for receiving selection for the plurality of series, A determining unit that determines the number of divisions of a display area in which medical images of the series are arranged according to the number of series that has been selected by the selection receiving unit, and a display area that is divided by the number of divisions determined by the determining unit And an arrangement means for arranging a series of medical images whose selection has been received by the selection receiving means.

  According to the present invention, it is possible to easily lay out a plurality of series of medical images.

Also, at the interpretation center, a business terminal 102 for performing a business relating to an interpretation request and an interpretation terminal 103 (medical image diagnostic apparatus) for interpretation by the interpretation doctor are connected to the LAN. Further, in the data center, an interpretation management server 104 for managing interpretation requests, an image management server 105 for managing medical images, and a database server 106 for managing various data tables are connected to the LAN. ing. Services provided by various servers connected to the data center are provided as so-called cloud services. In the present embodiment, the description will be divided into three locations, the requested facility, the interpretation center, and the data center. However, since there are various system configurations, the present invention is not limited to this.

  In the present embodiment, the network 107 is assumed to be the Internet protected by a VPN (Virtual Private Network) or the like, but is not limited thereto. Moreover, although the request | requirement facility in this embodiment assumes the medical examination organization which performs a medical examination, it is not restricted to this in particular.

  First, the main flow of image interpretation in this embodiment will be described. At the requested facility, the subject is imaged by a modality that is a medical image imaging device, and a medical image is generated. The medical image is, for example, DICOM (Digital Imaging and Communication in Medicine) standard image data. The DICOM standard medical image includes supplementary information called a DICOM tag, and information such as examination date, patient name, examination type, and part is stored in the accompanying information.

  When the medical image is generated, the medical image is transmitted from the request terminal 101 or the modality to the image interpretation management server 104. Upon receiving this, the image interpretation management server 104 transmits the received medical image to the image management server 105 and stores it in the external memory of the image management server 105.

  When the person in charge of interpretation request work at the requested facility inputs information necessary for the interpretation request (hereinafter referred to as interpretation request information) using the request terminal 101 and instructs the interpretation request, the request terminal 101 The interpretation request information is transmitted to the interpretation management server 104. Upon receiving the interpretation request information from the request terminal 101, the interpretation management server 104 transmits the received interpretation request information to the database server 106 and stores it in the external memory of the database server 106.

To decide.

  An interpreting doctor who interprets an image corresponds to an interpretation request assigned to himself / herself using the interpretation terminal 103 arranged at the interpretation center (or an interpretation terminal arranged at the interpretation doctor's home). A medical image is downloaded from the image management server 105. Thereafter, the interpretation doctor displays the downloaded medical image with a medical image viewer, interprets it, and creates an interpretation report describing the findings of the interpretation result using an application operating on the interpretation terminal 103. The completed interpretation report is transmitted to the interpretation management server 104, stored in the database server 106, and the request terminal 101 that has requested the interpretation displays the interpretation report. In this example, the example of the interpretation center and the interpretation doctor's home is shown as the interpretation terminal. However, the interpretation terminal may be placed in any location, and may be referred to using a mobile terminal or the like. The interpretation work is performed as described above.

  FIG. 3 is a diagram illustrating an example of a functional configuration of the image interpretation terminal 103. Note that the functional configuration shown in FIG. 3 is merely an example, and there are various configuration examples depending on applications and purposes, and the present invention is not limited to this. The detailed functions of each functional unit will be described in each flowchart described later.

  The interpretation terminal 103 includes a communication control unit 301, a display control unit 302, an input control unit 303, an arithmetic control unit 304, and a medical image management unit 305 as functional units.

  The communication control unit 301 is a functional unit for controlling transmission and reception of information with the image interpretation management server 104 and other various devices. The function of the communication control unit 301 transmits various information acquisition requests to the image interpretation management server 104 and other various devices via the network 107, and various information transmitted from the image interpretation management server 104 in response to the acquisition requests.

In addition, the medical image management unit 305 can refer to and acquire supplementary information of a medical image. The above is an example of the functional configuration of the image interpretation terminal 103.

  FIG. 4 is a flowchart illustrating an example of a processing flow from the start to the end of the medical image viewer. Steps S401 to S405 described below are processes executed by the CPU 201 of the image interpretation terminal 103 operating each function unit.

  Here, the patient, examination, series, and medical image in the present embodiment will be described. The patient, examination, series, and medical image in the present embodiment have the same meanings as indicated by the DICOM standards of Patient, Study, Series, and Image, respectively. These relationships are shown in FIG. As shown in FIG. 5, one or more examinations correspond to a patient, one or more series correspond to each examination, and a plurality of medical images correspond to each series. Hereinafter, based on these, a series of processing of this embodiment will be described.

  In step S <b> 401, the image interpretation terminal 103 activates a medical image viewer application stored in the external memory 211. The medical image viewer is installed in the interpretation terminal 103 in advance, but may be downloaded from a server device such as the interpretation management server 104 and activated in response to the start of interpretation. Further, the medical image viewer may be activated automatically in response to the start of interpretation, or may be activated in response to an instruction from the user.

  In step S <b> 402, the medical image management unit 305 of the image interpretation terminal 103 acquires from the image management server 105 a medical image of an examination for which an image interpretation request has been made. At this time, if there are a plurality of examinations requested for interpretation, all medical images corresponding to each examination are acquired. In this embodiment, the medical image is acquired from the image management server 105. However, if the medical image is stored in the external memory 211 in advance, it may be acquired from the external memory 211.

  In step S403, the display control unit 302 of the image interpretation terminal 103 displays a representative image of each series (hereinafter referred to as a series image) among the medical images acquired in step S402 in the image palette area of the medical image viewer. Since the medical image management unit 305 can identify the series image for each series by referring to the supplementary information, the thumbnail of the identified series image is displayed in the image palette area.

  FIG. 6 shows an example of the screen configuration of the medical image viewer 600. The medical image viewer 600 is an application that can display a medical image. The medical image viewer 600 includes an image palette area 601 for displaying thumbnails of series images and a display area 602 for laying out and displaying series images. The laid out series image can be switched to a medical image of the same series as the series image by receiving an operation such as rotating the mouse wheel. Further, a rearrangement button 603 for re-laying out the series image laid out in the display area 602 is also provided. Further, in the image palette area 601, a patient name, examination name, and series name are displayed so as to have a hierarchical structure as shown in FIG. 5, and a thumbnail of the series image is displayed in the vicinity of the series name. And the selection with respect to these can be received.

  The user of the medical image viewer selects one of the patient name (information indicating the patient), the examination name (information indicating the examination), and the series name (information indicating the series) displayed in the image palette area 601. A series image is laid out in the display area 602. When a patient name is selected, each series image of all examinations corresponding to the selected patient is laid out in the display area 602 (details will be described later with reference to FIG. 15). When an examination name is selected, each series image corresponding to the selected examination is laid out in the display area 602 (details will be described later with reference to FIG. 7). When the series name is selected, each selected series image is laid out in the display area 602 (details will be described later with reference to FIG. 14). In this embodiment, each name is selected, but information indicating each (for example, ID, image, etc.) may be selected. When the rearrange button 603 is pressed, each series image displayed in the display area 602 is laid out again (details will be described later with reference to FIG. 11). The medical image viewer can execute these processes in response to an instruction from the user until an end instruction of the medical image viewer is detected.

  In step S404, the input control unit 303 of the image interpretation terminal 103 determines whether or not a medical image viewer end instruction has been detected. For example, when a button for closing the medical image viewer or a menu for ending activation is pressed, it is determined that an instruction to end the medical image viewer has been detected. If it is determined that a medical image viewer termination instruction has been detected, the process proceeds to step S405, and the startup of the medical image viewer is terminated. Otherwise, step S404 is repeatedly executed until an end instruction is detected. The above is the description of FIG.

  FIG. 7 is a flowchart illustrating an example of a processing flow when an examination displayed on the medical image viewer 600 is selected. Steps S701 to S704 described below are processes executed by the CPU 201 of the image interpretation terminal 103 operating each function unit.

  In step S701, the input control unit 303 of the image interpretation terminal 103 determines whether selection for one or more examinations (examination names) displayed in the image palette area 601 has been detected (selection accepting unit). In the present embodiment, when the examination name displayed in the image palette area 601 is dragged and dropped into the display area 602, it is determined that selection for the examination has been detected. Further, when drag and drop with a plurality of examination names selected, it is determined that selection for a plurality of examinations has been detected. If it is determined that selection for one or more examinations has been detected, the process proceeds to step S702. Otherwise, step S701 is repeated until a selection for one or more tests is detected.

  In step S702, the calculation control unit 304 of the image interpretation terminal 103 adds the number of series corresponding to the selected examination (the number of the series for which selection has been accepted) to the number of series images already arranged (already arranged) in the display area 602. Number). The sum is Z.

  In step S <b> 703, the image interpretation terminal 103 executes display area division processing for determining the number (division number) for dividing the display area 602 in accordance with the number of series arranged in the display area 602. Details of the display area dividing process will be described below.

  FIG. 8 is a flowchart illustrating an example of a detailed process flow of the display area dividing process. Steps S801 to S808 described below are processes executed by the CPU 201 of the image interpretation terminal 103 operating each function unit.

  In step S <b> 801, the calculation control unit 304 of the image interpretation terminal 103 calculates the aspect ratio of the display area 602 of the medical image viewer 600. The aspect ratio changes depending on the size of the medical image viewer 600 displayed on the display 210. The aspect ratio can be calculated by dividing the length of the long side of the display area 602 by the length of the short side of the display area 602. Thereby, the ratio of the long side when the short side is “1” can be acquired. The following is an example in which Z, which is the number of series images to be arranged, is “6”, the long side length of the display area 602 is “1920”, and the short side length of the display area 602 is “1080”. explain. In step S801, as a result of the calculation, the aspect ratio is “1.77778” (rounded up to the sixth decimal place. If there is no problem in the accuracy of various calculations, any number may be rounded up).

  In step S <b> 802, the arithmetic control unit 304 of the image interpretation terminal 103 calculates the square root of a value obtained by multiplying Z by the aspect ratio, and sets this to X. The contents of this calculation formula will be specifically described below.

  First, in the present embodiment, it is desired to display all the series images to be displayed in the display area 602 side by side, and to prevent the display area 602 from being scrolled regardless of the number of series images. Therefore, it is necessary to consider how many display areas 602 should be divided to display all series images side by side without scrolling.

  Therefore, first, the horizontal length of each area (hereinafter referred to as a divided area) for dividing the display area 602 and arranging series images is x, and the vertical length is y. In addition, the length of the short side of the display area 602 is “1”, and the length of the long side is the aspect ratio value. FIG. 9 illustrates these based on the above-described example. In the above example, since the aspect ratio is “1.77778”, the length of the long side of the display area 602 is “1.77778”. Further, as shown in FIG. 9, the divided area 901 has a horizontal length x and a vertical length y. Assume further that x≈y.

  Arranging the divided areas 901 (x × y) in the display area 602 (1 × 1.7777) by the number (Z) of series images to be displayed means that “x × y × Z = 1 ×. 1.77778 ". Since x≈y, it is “Zx ^ 2 = 1.777778”, that is, “x = √ (1.777778 / Z)”.

  When the value for obtaining the number of divided areas 901 that can be arranged in the long side direction of the display area 602 is X, “X = 1.777778 / x”. If “x = √ (1.777778 / Z)” obtained previously is substituted here, “X = 1.777778 / √ (1.777778 / Z)” is obtained, and this becomes “X = 1.777778 × √”. (Z ÷ 1.77778) ”and finally“ X = √ (1.77778 × Z) ”. That is, as described above, the square root of the value obtained by multiplying Z and the aspect ratio is X, that is, a value for obtaining the number of divided regions 901 that can be arranged in the long side direction of the display region 602.

  In step S803, the arithmetic control unit 304 of the image interpretation terminal 103 rounds up the first decimal place of the X value calculated in step S802 to an integer, which can be arranged in DivX, that is, in the long side direction of the display area 602. The number of divided areas 901 is set (determining means). Although details will be described later, X may be rounded down.

  In step S804, the calculation control unit 304 of the image interpretation terminal 103 calculates Y, which is a value for obtaining the number of divided areas 901 that can be arranged in the short side direction of the display area 602 by dividing Z by DivX.

  In step S805, the arithmetic control unit 304 of the image interpretation terminal 103 rounds up the first decimal place of the Y value calculated in step S803 to an integer, which can be arranged in DivY, that is, in the short side direction of the display area 602. The number of divided areas 901 is set (determining means). Although details will be described later, Y may be rounded down.

  In this way, the number of divided areas that can be arranged in the long side direction of the display area 602 and the number of divided areas that can be arranged in the short side direction of the display area 602 are calculated. In the specific example described above, Z, which is the number of series images to be arranged, is “6”, the length of the long side of the display area 602 is “1920”, and the length of the short side of the display area 602 is “1080”. . Therefore, as a result of rounding up X, DivX becomes “4”, and as a result of rounding up Y, DivY becomes “2” (that is, provisionally determined). That is, if four columns are provided in the long side direction of the display area 602 and two rows are provided in the short side direction of the display area 602, a series image to be displayed can be arranged without scrolling the display area 602. Is possible.

  However, in steps S803 and S805, X and Y are each rounded up to an integer. Therefore, there is a possibility that a larger number of divided areas than the originally necessary divided areas may be created. For this reason, adjustment is performed in steps S806 and S807 described below.

  In step S806, the arithmetic control unit 304 of the image interpretation terminal 103 multiplies the result obtained by subtracting “1” from DivX and DivY, and determines whether or not this is equal to or greater than Z. That is, even if the number of divided areas that can be arranged in the long side direction of the display area 602 is reduced by one, it is tried whether or not all series images to be displayed can be arranged. If it is determined that the value is greater than or equal to Z, the process proceeds to step S807. If it is determined that it is not equal to or greater than Z, no adjustment is necessary, and the process proceeds to step S808.

  In step S807, the calculation control unit 304 of the image interpretation terminal 103 subtracts “1” from DivX, and sets this as new DivX (decision unit). That is, DivX is decremented. In the example described above, Z is “6”, DivX is “4”, and DivY is “2”. In other words, if a divided area corresponding to 4 horizontal rows × 2 vertical columns = 8 squares is provided, all series images to be displayed can be arranged. However, if 1 is subtracted from DivX, 3 horizontal rows × vertical 2 columns are obtained. Even in such a case, since the divided areas for 6 squares are provided, it can be seen that all series images can be arranged. Therefore, DivX is finally determined as “3” and DivY as “2”. In this way, final adjustment is performed so that unnecessary divided areas are not generated.

  In step S <b> 808, the display control unit 302 of the image interpretation terminal 103 provides columns so that there are as many divided areas as DivX in the long side direction of the display area 602, and as many divided areas as DivY in the short side direction of the display area 602. Provide a line so that That is, the display area 602 is divided using DivX and DivY, which are division numbers. Thereby, the divided area for arranging the series image is generated. When the division of the display area 602 is completed, the display area division process is terminated, and the process is returned to the caller of the display area division process.

  In the display area dividing process according to the present embodiment, X and Y are rounded up in steps S803 and S805, but the present invention is not limited to this. For example, after X is rounded down and Y is rounded up, it is determined whether or not “Z <= DivX × DivY” is satisfied in step S806. When this is satisfied, DivX adjustment is not performed, but when this is not satisfied, DivX may be incremented to increase the number of columns. Further, after rounding up X and rounding down Y, it is determined in step S806 whether or not “Z <= DivX × DivY” is satisfied. When this is satisfied, DivY is not adjusted, but when this is not satisfied, DivY may be incremented to increase the number of columns. In this way, the final adjustment may be performed by increasing or decreasing the number of divisions.

  Further, in the present embodiment, the number of divisions of the display area 602 is determined according to the number of series arranged in the display area 602. However, in this embodiment, the number of vertical and horizontal divisions is stored in advance for each number of series. Also good.

  Returning to FIG. In step S704, the display control unit 302 of the image interpretation terminal 103 displays each series image already laid out in the display area 602 in the divided area generated by the display area dividing process, and each series of examinations selected in step S701. Arrange with images. It does not matter in particular in which divided area the series image is arranged and in what order. When the arrangement is completed, the information is displayed on the display 210, and the series of processes shown in FIG.

  FIG. 10 shows the division result of the above example (DivX is “3” and DivY is “2”). FIG. 10 shows an execution result when “inspection 1” displayed in the image palette area 601 is selected (that is, Z = 6, the length of the long side of the display area 602 = 1920, and the short side of the display area 602). The result when length = 1080). In this way, the display area can be divided so that an appropriate number of divided areas are generated according to the number of series images. Is possible.

  Incidentally, as shown in FIG. 10, a close button 604 for closing (not displaying) the arranged series image is provided for each divided region. When a press on the close button 604 is accepted, the series image arranged in the divided area including the pressed close button 604 is hidden. That is, the arranged series image is removed from the divided area. FIG. 12 shows a medical image viewer 600 when two series images of the series images arranged in FIG. 10 are not displayed. In this state, the display area 602 is occupied by a divided area where nothing is arranged. In such a case, the user can redo the layout of the currently arranged series image by pressing the rearrangement button 603. This will be described below with reference to FIG.

  FIG. 11 is a flowchart illustrating an example of a processing flow when the rearrangement button 603 is pressed. Steps S1101 to S1104 described below are processes executed by the CPU 201 of the image interpretation terminal 103 operating each function unit.

  In step S1101, the input control unit 303 of the image interpretation terminal 103 determines whether or not pressing of the rearrangement button 603 is detected. If it is determined that pressing of the rearrange button 603 has been detected, the process proceeds to step S1102. If not, step S1101 is repeatedly executed until the pressing of the rearrangement button 603 is detected.

  In step S1102, the calculation control unit 304 of the image interpretation terminal 103 sets Z as the number of series images already arranged in the divided area.

  In step S1103, the image interpretation terminal 103 executes a display area dividing process. In step S1103, the value of Z defined in step S1102 is used. Since the display area dividing process is as described above, a description thereof will be omitted.
