Description

  The present invention relates to an image display technique for displaying a screen on which a dialog box image having various icons together with a medical image is arranged.

  In the medical field, various image diagnostic apparatuses such as an X-ray CT apparatus and an ultrasonic diagnostic apparatus, and various image display apparatuses such as a PACS, HIS, RIS, and an electronic medical record system are arranged. Each of these devices has a display unit such as a liquid crystal display or a CRT display, and displays a screen on which medical images of the photographed subject are arranged.

  On the screen of the diagnostic imaging apparatus or the image display apparatus, the displayed medical image is enlarged, reduced, or rotated, further an annotation is added to the medical image, the ROI is set in the medical image, or the set ROI is set. Operation buttons for receiving various operations such as analysis are arranged in an icon image format. This icon image is arranged in an area called a dialog box. The dialog box image with the icon image is floated from the viewpoint of improving convenience, and the display position in the screen is freely movable.

  The operator displays the image of the dialog box at a desired position, calls the function by pressing the icon image, and then performs a detailed operation of the function by operating the mouse on the medical image. In such an operation, when the dialog box image and the medical image are displayed in an overlapping manner, the boundary between the dialog box image and the medical image is not clear, so it is determined which image is being operated. It was difficult to do.

  In view of this, conventionally, a technique for providing a fixed border to a thumbnail image, a predetermined icon image, a window, or the like has been proposed (see, for example, “Patent Document 1”).

In this prior art, no matter what medical image is displayed, the border is drawn with a predetermined color scheme. In recent years, various photographing methods for photographing a medical image have been presented, and the color of a medical image often varies depending on the photographing method.
As a medical image photographing method, an ultrasonic image photographing method, that is, photographing based on ultrasonic transmission / reception by an ultrasonic diagnostic apparatus, or an X-ray CT image photographing method, that is, X around a subject by an X-ray CT apparatus is used. Imaging based on exposure of X-rays, imaging system of X-ray images, that is, imaging based on exposure of X-rays from one of the subjects by an X-ray diagnostic apparatus, imaging system of MRI images, that is, magnetic resonance images Examples include imaging based on magnetic resonance signals generated in a subject by a diagnostic device, and imaging methods for nuclear medicine images, that is, imaging based on detection of gamma rays emitted from radioisotopes by a nuclear medicine diagnostic device.

  Then, with the technology that performs bordering with one predetermined color scheme, when the medical image of one imaging method and the image in the dialog box overlap, there is a clear difference between the bordering color and the color of the medical image. The border between the box image and the medical image is clear, but when the medical image of another imaging method and the dialog box image overlap, there is no clear difference between the color of the border and the color of the medical image May occur.

  In other words, with the conventional technique for fixed edging, in recent years when there are medical images of various photographing methods, it has not always been possible to clarify the boundary between the dialog box image and the medical image.

Furthermore, the border processing unit 71 fills the border 122 of the dialog box image 120 with the color indicated by the read border color information 80 (S30).

  When the generation of the screen 100 is completed, the screen creation unit 7 outputs the screen 100 to the display unit 2 to display the screen 100 on which the medical image 110 and the dialog box image 120 are arranged on the display unit 2 (S31).

  As described above, in the image display apparatus 1, the dialog box image is also displayed with the edge color information 80 corresponding to the imaging method of the medical image 110 by specifying the imaging method of the image diagnostic apparatus M that has transmitted the medical image 110 from the apparatus information. 120 edges 122 may be trimmed.

  Next, the edge 122 of the dialog box image 120 is edged with the edge color information 80 corresponding to the photographing method of the medical image 110 in accordance with the modality information indicating the model of the photographed diagnostic imaging apparatus M attached to the medical image. A specific example of 3 will be described with reference to FIGS.

  FIG. 8 is a block diagram showing a more detailed configuration of the image display apparatus 1 according to the third specific example. The same configurations or functions as those of the image display apparatus 1 of the first specific example are denoted by the same reference numerals, and detailed description thereof is omitted.

  In the image display apparatus 1 according to the third specific example, the edge color setting unit 64 acquires information for recognizing the imaging method of the medical image 110 from the medical image storage unit 5. In addition to the image data indicating the image of the subject, the medical image 110 includes a plurality of elements each having a tag and information as a pair. The edge color setting unit 64 acquires modality information among the elements. The modality information is information for identifying the type of the diagnostic imaging apparatus M that has captured the accompanying medical image 110. For example, the modality information is a data string indicating an X-ray CT apparatus or a data string indicating an ultrasonic diagnostic apparatus. Since one imaging method is determined for the modality information, this modality information is information for specifying the imaging method of the attached medical image.

  In the edge color information table 82, modality information for uniquely specifying the shooting method is stored as shooting method information 83, and this modality information and the edge color ID 81 are associated with each other. The edge color setting unit 64 selects the edge color information 80 from the modality information that specifies the imaging method of the attached medical image, and stores it in the edge color information storage unit 63.

(Second Embodiment)
Next, the image display apparatus 1 according to the second embodiment will be described. FIG. 10 is a block diagram showing a configuration of the image display device 1 according to the second embodiment. FIG. 11 is a diagram illustrating a screen 100 displayed by the image display device 1 according to the second embodiment.

  As shown in FIG. 11, the image display device 1 according to the second embodiment is configured to trim the edge 122 of the dialog box image 120 with a color scheme according to the imaging method of the medical image 110 in the aspect of the first embodiment. In addition, when the dialog box image 120 and the medical image 110 overlap with each other, a different edging is performed on the overlapping portion 123 existing at the edge 122 of the overlapping region op.

  For the overlapping portion 123 of the edge 122, a color different from the hue of the overlapping region op of the medical image 110 is selected. For example, the medical image 110 may be subjected to processing such as coloring the blood flow velocity measurement result on the medical image 110. When the hue of the overlapping region op of the medical image 110 is changed from the hue according to the original photographing method by the processing after the coloring or the like, the border having a clear difference is performed corresponding to the change in the hue. Can do.

  For example, when the medical image 110 is an ultrasound image, an ROI that represents the blood flow velocity in color is set in the medical image 110. When this ROI and the dialog box image 120 overlap, the edge 122 corresponding to the ultrasound image is displayed. The color arrangement may not always have a clear difference from the color in the ROI at the overlapping portion 123 of the edge 122. Therefore, the overlapping portion 123 of the edge 122 is changed to a color having a clear difference from the hue of the overlapping region op including the ROI.

  As shown in FIG. 10, the component storage unit 6 of the image display device 1 further includes a display position calculation unit 65, an overlap detection unit 66, an overlap part distributed color information creation unit 67, and an overlap part border information storage unit 68.

  According to a further configuration of the component storage unit 6, an overlap between the dialog box image 120 and the medical image 110 at the movement destination is detected in accordance with a movement operation of the display position of the dialog box image 120, and the detected overlap area op Based on the hue before the movement of the dialog box image 120, overlapping portion distribution color information indicating a hue farthest from this hue is created, and the overlapping portion 123 of the edge 122 is filled with the color indicated by the overlapping portion distribution color information.

  The display position calculation unit 65 calculates the display position of the dialog box image 120. The display position is calculated using a drag-and-drop operation of the dialog box image 120 using the operation unit 3 as a trigger. Specifically, the vector amount (x, y) indicating the movement amount of the dialog box image 120 is added to a value indicating the coordinate D serving as a reference for the display position of the movement source. The coordinates obtained by this addition become new reference information after movement.

  The overlap detection unit 66 detects the overlap between the dialog box image 120 and the medical image 110 and stores the range information of the overlap region op in the overlap partial border information storage unit 68.

  FIG. 12 is a schematic diagram showing how the overlap detection unit 66 detects an overlap.

  The overlap detection unit 66 uses the coordinates D indicated by the reference information of the moved dialog box image 120 calculated by the display position calculation unit 65 and the width W and height H of the dialog box image 120 including the dialog box information. The coordinate range in which the dialog box image 120 is displayed is calculated.

  Then, the overlap detection unit 66 acquires the drawing data of the screen 100 before the movement of the dialog box image 120 from the screen creation unit 7, and sequentially scans within the coordinate range where the dialog box image 120 is displayed, The pixel value of the pixel before the dialog box image 120 is moved is compared with the threshold value stored in advance. As a result of the comparison, the coordinate range of the pixel group having a pixel value exceeding the threshold value is set as the range information of the overlapping region op. As the threshold value, a boundary value between a gradation value range that the medical image 110 generally has and a gradation value that the background of the screen has is selected, and pixels having a pixel value that exceeds the threshold value constitute the medical image 110. Pixel.

  The overlapping portion distribution color information creation unit 67 creates overlapping portion distribution color information of the overlapping portion 123 of the edge 122 from the hue of the overlapping region op and stores it in the overlapping portion border information storage unit 68. The overlapping portion distribution color information is created based on the color that borders the edge 122 of the dialog box image 120, that is, the edge color information 80 stored in the edge color information storage unit 63. The overlapping portion distribution color information creation unit 67 creates a histogram of the overlapping region op, and changes any of the R (red), G (green), and B (blue) component values constituting the edge coloring information 80 based on the histogram. Further, based on this histogram, the changed value is determined. Then, overlapping portion distribution color information is generated by replacing the changed value and the changed component value, and is stored in the overlapping portion border information storage unit 68 together with the range information of the overlapping region op.

  FIG. 13 is a schematic diagram illustrating a histogram of the overlapping region op.

  The overlapping portion distribution color information creating unit 67 creates a histogram of the overlapping region op for each color of RGB. The histogram is a graph obtained by accumulating the number of pixels for each gradation value.

  The overlapping portion distribution color information creation unit 67 searches for a gradation value having the maximum number of pixels from the histogram of all RGB components, and changes the color component having the gradation value having the maximum number of pixels to the color component to be changed. To do. For example, in the R component, the number of pixels having a gradation value of “200” is a peak value, in the G component, the number of pixels having a gradation value of “150” is a peak value, and in the R component, “100 It is assumed that the number of pixels having a gradation value of “is a peak value. Further, it is assumed that the peak value of the R component is “100”, the peak value of the G component is “70”, and the peak value of the B component is “50”. At this time, since the number of pixels having the gradation value of “200” of the R component among all the RGB components takes the maximum value of “100”, the overlapping portion distribution color information creation unit 67 stores in the edge coloration information storage unit 63. It is determined to create overlapping portion distribution color information having a different R component from the stored edge color information 80.

  The overlapping portion distribution color information creation unit 67 stores a plurality of change value points cp indicating predetermined gradation values in advance. Each change value point cp has a different value. For example, the overlapping portion distribution color information creation unit 67 stores in advance each change value point cp indicating gradation values of “0”, “50”, “100”, “150”, “200”, and “255”. Yes. Further, the overlapping portion distribution color information creation unit 67 stores in advance a range value sp indicating a predetermined range on the axis where the gradation values are arranged. For example, the range value sp has a value of “100”.

  The overlapping portion distribution color information creation unit 67 storing the change value point cp and the range value sp is within the range value sp from the tone value corresponding to the peak value of the color component to be changed, and this tone value. The gradation value indicated by the change value point cp having the value farthest from is set as the pixel value of the color component to be changed.

  Then, the overlapping portion distribution color information creation unit 67 creates overlapping portion distribution color information included in the color component for changing the obtained gradation value from the edge color information 80.

  FIG. 14 is a diagram illustrating an aspect in which overlapping portion distribution color information is created from the edge color information 80. The overlapping portion distribution color information creation unit 67 has the gradation value indicated by the change value point cp that has the pixel value of the color component to be changed in the edge color information 80 within the range value sp and has the value farthest from the gradation value. Overlapping portion distribution color information is created in place of the pixel value corresponding to the value. That is, in the edge color information 80 and the overlapping portion distribution color information, the color components other than the color component to be changed have the same pixel value.

  For example, if the color component to be changed is the R component and the gradation value having the peak value is “200”, the change value point cp having the gradation value “100” is within the range value sp, and Since the R component has a pixel value of “100” because it is a value farthest from the gradation value, overlapping portion distribution color information in which the other G component and B component are the same as the edge color information 80 is created.

  The border processing unit 71 of the screen creation unit 7 borders the edge 122 of the dialog box image 120 in accordance with the imaging method of the medical image 110 and further borders the overlapping portion 123 of the edge 122 with a different color. The border processing unit 71 reads the range information of the overlap region op and the overlap portion distribution color information from the overlap portion border information storage unit 68, and among the pixels constituting the dialog box image 120, the pixels included in the range information The adjacent pixels are filled with the color indicated by the overlapping color scheme information. The reason why the pixels included in the range information and the adjacent pixels are used is to fill the overlapping portion 123 of the edge 122 with a certain thickness.

  By the edging process of the overlapping portion 123 of the edging processing unit 71, the dialog box image 120 in which the overlapping portion 123 that overlaps the medical image 110 of the rim 122 is further edged is displayed on the screen 100 of the display unit 2.

  FIG. 15 is a flowchart showing a further edging operation of the overlapping portion 123 of the image display apparatus 1 according to the second embodiment.

  First, the component storage unit 6 fills the entire periphery of the edge 122 of the dialog box image 120 with the color indicated by the edge color information 80 corresponding to the imaging method of the medical image 110 (S51). Then, the component storage unit 6 waits until the display position of the dialog box image 120 is changed using the operation unit 3 (S52, No), and when the display position of the dialog box image 120 is changed (S52, Yes). ) The display position calculation unit 65 calculates a new reference for the display position and sets it as new reference information (S53).

  When the new reference information is obtained, the overlap detection unit 66 compares each pixel value in the range indicated by the width and height indicated by the dialog box information with the new reference information as a reference and the threshold value (S54). The coordinate range of the pixel group having the pixel value exceeding the threshold value is stored in the overlapping partial border information storage unit 68 as the range information of the overlapping region op (S55).

  When the range information of the overlapping area op is obtained, the overlapping part distributed color information creating unit 67 creates a histogram for each RGB component of the area corresponding to the overlapping area op before the dialog box image 120 moves (S56). . Then, the overlapping portion distribution color information creation unit 67 searches for the gradation value having the maximum number of pixels and the color component to which the gradation value belongs from the histogram of all RGB components (S57). When the corresponding gradation value is searched, the overlapping portion distribution color information creation unit 67 reads the predetermined range value sp and each change value point cp, and is within the range value sp based on the corresponding gradation value. And the change value point cp farthest from the corresponding gradation value is searched (S58).

  When the corresponding change value point cp is searched, the overlapping portion distribution color information creation unit 67 reads the edge color information 80 from the edge color information storage unit 63 (S59). Then, the overlapping portion distribution color information creation unit 67 overlaps the distribution color information corresponding to the data in which the color component searched in S57 of the read edge color information 80 is changed to the gradation value indicated by the corresponding change value point cp. Is created (S60), and is stored in the overlapping partial border information storage unit 68 different from the edge color information storage unit 63 (S61).

  When the processing of S51 to S61 ends, the border processing unit 71 of the screen creation unit 7 reads the range information of the overlap region op and the overlap portion distribution color information from the overlap portion border information storage unit 68 (S62), and displays a dialog box image. Among the pixels constituting 120, each pixel included in the range information of the overlapping area op is filled with the color indicated by the overlapping portion distribution color information (S63).

  According to the image display device 1 according to the second embodiment, a portion of the edge 122 of the dialog box image 120 that overlaps the medical image 110 is further bordered with a color different from the color of the overlapping region op. Therefore, the dialog box image 120 and the medical image 110 can be distinguished even when the color of the overlapping area op of the medical image 110 is changed from the color corresponding to the original imaging method. Accordingly, it is possible to more clearly determine whether the medical image 110 is being operated or the icon image 121 in the dialog box image 120 is being operated, so that concentration is not lacking and work efficiency is improved. To do.

  In the image display device 1 according to the second embodiment, the range value sp is stored in advance, and the gradation value of the change point cp that is within the range and has the most difference is determined as the color to be changed. The tone value of the change point cp having the most difference may be determined as a color for changing without limiting the range value sp.
