Description

Technical Field

[0001] The present invention provides a device for an image editor, and particularly relates to a device for a medical image editor that can edit various medical images. Background Art

[0002] For a long time, medical imaging contrast technologies have been increasingly refined. For example, technologies such as MRI, MRA, and CT have long been widely used in medical examinations. After a medical unit obtains various medical examination images, it usually needs to use a medical image browser to view the patient's contrast images (medical images), and then use the editor in the browser or a separate editor to manually mark the patient's lesion area clearly on the patient's contrast image with a marking line, so as to facilitate doctors to analyze the patient's condition and further determine the subsequent medical plan based on the marked lesion.

[0003] In recent years, with the rapid development of medical AI technology, the lesion marking on contrast images has gradually developed from a manual marking method to an AI automatic marking method. However, whether medical staff mark the patient's lesion area on the patient's image manually or use the AI automatic method, incorrect marking or poor marking quality will occur. At this time, medical staff must use the correction tools provided by the medical image editor to correct the marking line.

[0004] As mentioned above, a common marking line correction tool is as follows Figure 1 As shown, the correction method is that the user can select a plurality of marking points 90 in the area near the line segment XY of the marking line 9 to be corrected by himself, and then connect the plurality of marking points 90 to form a corrected marking line segment 91, that is, as Figure 2 shown by the dotted line. In terms of this correction method, when the marking line segment to be marked is relatively long, the user must use a lot of marking points 90 to complete the correction, or when the shape of the marking line segment to be marked is relatively special, the user may not be able to accurately present the required line segment form through the plurality of marking points 90.

[0005] Of course, in addition to the above correction tools, there are many different types of correction tools for well-known medical image correction tools. In addition, in a general well-known medical image editor, there is usually a zoom tool that allows the user to enlarge or reduce the entire area or a relatively large range of line segments of the marking line. However, in all the correction tools of the currently well-known editors, there is a common problem, that is, it is difficult for the user to quickly and conveniently correct the actual marking line contour of the patient's lesion, and thus it takes a relatively long time to complete the correction. That is, for the zoom tool for enlarging or reducing the entire area or a relatively large range of line segments, there are also similar problems.

[0006] In summary, how to provide a device for users to quickly, conveniently and accurately correct the annotation lines of medical images is indeed a major issue. Summary of the Invention

[0007] Therefore, an object of the present invention is to provide a device for a medical image editor that allows users to quickly, conveniently and accurately correct the annotation lines of medical images.

[0008] To achieve the above object, the present invention provides a device for a medical image editor, which includes a display and an electronic calculator connected to each other. A cursor is displayed on the display, and at least one medical image with annotation lines is displayed; the electronic calculator can be used for the medical image editor to execute. The medical image editor includes a deformation tool for correcting the annotation lines in the medical image; the deformation tool includes at least one deformation pattern and a deformation vector pattern. One end of the deformation vector pattern is combined with the deformation pattern to form the pattern of the deformation tool; wherein, the deformation tool causes a partial line segment of the annotation line to generate a certain proportion of deformation according to the deformation pattern in the direction indicated by the deformation vector pattern.

[0009] In one embodiment, the deformation tool operates through the cursor.

[0010] In one embodiment, the other end point of the deformation vector pattern is respectively connected to the two end points of the deformation pattern to form a first deformation line segment adjustment line and a second deformation line segment adjustment line. The first deformation line segment adjustment line and the second deformation line segment adjustment line are respectively connected to the annotation line, and the line segment between the two connection points generates deformation according to the shape of the deformation pattern.

[0011] In one embodiment, the shape of the deformation pattern is changed by adjusting the angle between the first deformation line segment adjustment line and the second deformation line segment adjustment line.

[0012] In one embodiment, a pattern shape adjustment symbol is provided at the intersection of the deformation vector pattern and the deformation pattern, and the shape of the deformation pattern is changed by adjusting the position change of the pattern shape adjustment symbol.

[0013] In one embodiment, a deformation position designation symbol is provided on the deformation vector pattern, and the deformation position designation symbol can move in the extension direction of the deformation vector pattern. The line segment of the annotation line after deformation passes through the point designated by the deformation position designation symbol.

[0014] In one embodiment, a partial line segment of the annotation line generates deformation by clicking on the pattern of the deformation tool with the cursor.

[0015] In one embodiment, the deformation pattern can be a curve pattern, an arrow cone pattern, a linear pattern, or a zigzag pattern.

[0016] Since the deformation tool of the device of the medical image editor according to the present invention can replace the deformation pattern of the deformation tool according to the change requirements of the annotation line, the annotation line can be corrected more accurately. In addition, since the user can directly select different deformation patterns to achieve the correction purpose, the user can quickly, conveniently and accurately correct the annotation line of the medical image. In other words, by means of the device of the medical image editor according to the present invention, the annotation time can be saved, and thus the efficacy of accurate treatment can be improved.

[0017] In another embodiment, the medical image editor further includes a scaling tool, which includes a scaling pattern and a scaling vector pattern. The scaling vector pattern is combined with the scaling pattern to form the pattern of the scaling tool. Among them, the scaling tool scales a part or all of the line segments of the annotation line in a certain proportion according to the state of the original line segment in the vector direction indicated by the scaling vector pattern.

[0018] In another embodiment, the scaling pattern is a closed curve pattern.

[0019] In another embodiment, the scaling vector pattern is an enlargement vector pattern or a reduction vector pattern.

[0020] In another embodiment, the enlargement vector pattern includes a first enlargement vector pattern and a second enlargement vector pattern pointing from the center of the circle to the circumference; and the reduction vector pattern includes a first reduction vector pattern and a second reduction vector pattern pointing from the circumference to the center of the circle.

[0021] In another embodiment, a first enlarged line segment adjustment line is formed in the extending direction of the first enlargement vector pattern; and a second enlarged line segment adjustment line is formed in the extending direction of the second enlargement vector pattern. The first enlarged line segment adjustment line and the second enlarged line segment adjustment line are respectively connected to the annotation line, and the line segment between the two connection points is enlarged in a certain proportion according to the state of the original line segment.

[0022] In another embodiment, a first reduced line segment adjustment line is formed in the extending direction of the first reduction vector pattern; and a second reduced line segment adjustment line is formed in the extending direction of the second reduction vector pattern. The first reduced line segment adjustment line and the second reduced line segment adjustment line are respectively connected to the annotation line, and the line segment between the two connection points is reduced in a certain proportion according to the state of the original line segment.

[0023] In another embodiment, when the first enlargement vector pattern and the second enlargement vector pattern of the enlargement vector pattern overlap, the scaling tool can enlarge the annotation line in all directions of 360 degrees.

[0024] In another embodiment, when the first reduction vector pattern and the second reduction vector pattern of the reduction vector pattern overlap, the scaling tool can reduce the annotation line in all directions of 360 degrees.

[0025] In another embodiment, the enlarged vector pattern further includes a third enlarged vector pattern pointing from the center of the circle to the circumferential direction; and the reduced vector pattern further includes a third reduced vector pattern pointing from the circumference to the center of the circle.

[0026] In another embodiment, an enlarged position designation symbol is provided in the direction in which the third enlarged vector pattern extends. The enlarged position designation symbol moves in the direction in which the third enlarged vector pattern extends, and all or part of the enlarged line segments of the marking line pass through the point designated by the enlarged position designation symbol.

[0027] In another embodiment, a reduced position designation symbol is provided in the direction in which the third reduced vector pattern extends. The reduced position designation symbol moves in the direction in which the third reduced vector pattern extends, and all or part of the reduced line segments of the marking line pass through the point designated by the reduced position designation symbol.

[0028] Since the scaling tool of the device of the medical image editor of the present invention can enlarge or reduce all or part of the marking line by a certain proportion according to the state of the original line segment, the user can quickly and conveniently correct the marking line of the medical image, and by cooperating with the aforementioned deformation tool, the marking line can be corrected more precisely.

[0050] To avoid repetition, before describing the specific embodiments of the present invention, the relevant terms used in the present invention are defined as follows:

[0051] The so-called "electronic calculator" refers to all computers with a CPU or GPU, including, for example but not limited to, desktop computers, laptop computers, tablet computers, mobile phones and other electronic devices. The so-called "medical image editor" refers to an editor that can edit various medical image file formats such as DICOM, RTSS, Nifti, or Analyze.

[0052] In addition, in the embodiments of the present invention, the so-called "symbol" or "pattern" that has a similar or approximate visual effect should be regarded as the "symbol" or "pattern" with the same function.

[0053] As Figure 3 shown, the device 1 of the medical image editor of the present invention includes a display 2 and an electronic calculator 3 connected to each other. A cursor 20 is displayed on the display 2, and at least one medical image 21 with an annotation line 211 formed thereon is displayed. The electronic calculator 3 can be used for the medical image editor to execute.

[0054] As Figure 4 or Figure 5 shown, the medical image editor includes a deformation tool 4 for correcting the annotation line 211 in the medical image 21. The deformation tool 4 includes at least one deformation pattern 41 and a deformation vector pattern 42. One end point C of the deformation vector pattern 42 is combined with the deformation pattern 41 to form the pattern of the deformation tool 4. The deformation tool 4 deforms a partial line segment of the annotation line 211 in a certain proportion according to the deformation pattern 41 in the direction indicated by the deformation vector pattern 42.

[0055] In this embodiment, the deformation pattern 41 can be a curve pattern (as Figure 4 shown), a arrow cone pattern (as Figure 5 shown), a linear pattern (not shown), or a zigzag pattern (not shown). The other end point D of the deformation vector pattern 42 is respectively connected to the two end points A and B of the deformation pattern 41 to form a first deformation line segment adjustment line L1 and a second deformation line segment adjustment line L2.

[0056] As Figure 6A or Figure 6B shown, the first deformation line segment adjustment line L1 and the second deformation line segment adjustment line L2 are respectively in contact with the marking line 211, and the line segment between the two contact points E and F is deformed according to the pattern of the deformation pattern 41. It is worth mentioning here that, as Figure 6A and Figure 6B shown, the user moves point D through the cursor 20 and rotates around point C, thereby changing the direction of the deformation vector pattern 42 of the deformation tool 4. In addition, the position of the deformation tool 4 can also be moved through the cursor 20.

[0057] In addition, in this embodiment, the pattern of the deformation pattern 41 can be adjusted by adjusting the included angle between the first deformation line segment adjustment line L1 and the second deformation line segment adjustment line L2. As Figure 8 shown, the deformation pattern 41 in it is a curve pattern. When the included angle θ1 between the first deformation line segment adjustment line L1 and the second deformation line segment adjustment line L2 is changed to the included angle θ2, the pattern of the deformation pattern 41 changes from a relatively long curve pattern to a shorter curve pattern (as shown in the right diagram of Figure 8 ). Another example is that, as Figure 9 shown, the deformation pattern 41 in it is an arrow cone pattern. When the included angle θ1 between the first deformation line segment adjustment line L1 and the second deformation line segment adjustment line L2 is changed to the included angle θ2, the pattern of the deformation pattern 41 changes from a larger arrow cone pattern to a smaller arrow cone pattern (as shown in the right diagram of Figure 9 ).

[0058] Please refer to Figure 4 or Figure 5 shown again. In the deformation vector pattern 42, there is a deformation position designation symbol T. In addition, as Figure 7 shown, the deformation position designation symbol T can be moved in the extending direction of the deformation vector pattern 42, so that the deformed line segment of a part of the marking line 211 passes through the point designated by the deformation position designation symbol T.

[0059] Furthermore, in addition to being able to adjust the pattern of the deformation pattern 41 by adjusting the included angle between the first deformation line segment adjustment line L1 and the second deformation line segment adjustment line L2, in the present invention, at the junction of the deformation vector pattern 42 and the deformation pattern 41, there is a pattern adjustment symbol S, and the pattern of the deformation pattern 41 can also be changed by adjusting the position of the pattern adjustment symbol S (S→S'). As Figure 10 shown, the deformation pattern 41 in it is a curve pattern. When the position of the pattern adjustment symbol S is lifted (as shown in the right diagram of Figure 10 ), the pattern of the deformation pattern 41 changes from a relatively gentle curve pattern to a relatively curved curve pattern. As Figure 11The deformation pattern 41 shown is an arrow-cone pattern. When the position of the pattern state adjustment symbol S is lifted (as shown in the right diagram of Figure 11 ), the state of the deformation pattern 41 changes from an arrow-cone pattern with a relatively small sharpness to an arrow-cone pattern with a relatively large sharpness.

[0060] As described above, in this embodiment, after the user sets the state of the deformation pattern 41, the user can click on the pattern of the deformation tool with the cursor to cause a certain proportion of deformation of some line segments of the marking line to be in proportion to the deformation pattern 41. The change in the proportion of the deformation, for example, depends on the number of clicks. In addition, since the deformation pattern 41 of the deformation tool 4 of the present invention can be arbitrarily changed and the size of its state can also be arbitrarily adjusted, the user can conveniently and quickly find a suitable deformation tool 4 for various shapes of the marking line 211 and then effectively make corrections.

[0061] Furthermore, as shown in Figure 12A or Figure 12B , the medical image editor of the present invention further includes a zoom tool 5. The zoom tool 5 includes a zoom pattern 51 and a zoom vector pattern 52. The zoom vector pattern 52 is combined with the zoom pattern 51 (A', B') to form the pattern of the zoom tool 5. Among them, the zoom tool 5 causes some or all line segments of the marking line to be scaled in a certain proportion according to the state of the original line segment in the vector direction indicated by the zoom vector pattern 52.

[0062] As shown in Figure 12A , the zoom pattern 51 can be a closed curve pattern, such as a circle, and its center is D'. The zoom vector pattern 52 is an expansion vector pattern. In this example, the expansion vector pattern includes a first expansion vector pattern 521 and a second expansion vector pattern 522 pointing from the center to the circumference direction. A first expansion line segment adjustment line L3 is formed in the extension direction of the first expansion vector pattern 521; and a second expansion line segment adjustment line L4 is formed in the extension direction of the second expansion vector pattern 522.

[0063] As shown in Figure 13A , the first expansion line segment adjustment line L3 and the second expansion line segment adjustment line L4 are respectively connected to the marking line, and the line segment between the two connection points E' and F' is expanded in a certain proportion according to the state of the original line segment. The change in the proportion of the expansion, for example, depends on the number of clicks.

[0064] As shown in Figure 12BAs shown, the scaled pattern 51 can be a closed curve pattern, such as a circle, with its center at D'. The scaling vector pattern 52 is a shrinking vector pattern. In this example, the shrinking vector pattern includes a first shrinking vector pattern 524 and a second shrinking vector pattern 525 that point from the circumference towards the center of the circle. A first shrinking line segment adjustment line L5 is formed in the extending direction of the first shrinking vector pattern 524; and a second shrinking line segment adjustment line L6 is formed in the extending direction of the second shrinking vector pattern 525.

[0065] As Figure 13B shown, the first shrinking line segment adjustment line L5 and the second shrinking line segment adjustment line L6 respectively intersect with the marking line. The line segment between the two intersection points E' and F' is shrunk by a certain proportion according to the shape of the original line segment, and the magnitude of the shrinking proportion changes, for example, according to the number of clicks.

[0066] In addition, please refer again to Figure 12A or Figure 12B shown, wherein, the expanding vector pattern further includes a third expanding vector pattern 523 that points from the center of the circle towards the circumference; and the shrinking vector pattern further includes a third shrinking vector pattern 526 that points from the circumference towards the center of the circle. As Figure 14 shown, an expansion position designation symbol M is provided on the third expanding vector pattern 523. The expansion position designation symbol M moves in the extending direction of the third expanding vector pattern 523, and all or part of the line segments of the marking line 211 after expansion pass through the point designated by the expansion position designation symbol M; in other words, the user can directly adjust the position of the expansion position designation symbol M to expand all or part of the line segments of the marking line 211 at one time. Additionally, a shrinking position designation symbol Z is provided on the third shrinking vector pattern 526. The shrinking position designation symbol Z moves in the extending direction of the third shrinking vector pattern 526, and all or part of the line segments of the marking line 211 after shrinking pass through the point designated by the shrinking position designation symbol Z; in other words, the user can directly adjust the position of the shrinking position designation symbol Z to shrink all or part of the line segments of the marking line 211 at one time.

[0067] Furthermore, as Figure 15A shown, in this embodiment, when the first expanding vector pattern 521, the second expanding vector pattern 522, and the third expanding vector pattern 523 overlap each other; or when the first expanding line segment adjustment line L3 and the second expanding line segment adjustment line L4 overlap each other, the scaling tool 5 of the present invention can expand the original marking line 211 in a 360-degree all-round manner, as Figure 16A shown (211 → 211'). By the same token, as Figure 15BAs shown, in this embodiment, when the first reduced vector pattern 524, the second reduced vector pattern 525, and the third reduced vector pattern 526 overlap with each other; or when the first reduced line segment adjustment line L5 and the second reduced line segment adjustment line L6 overlap with each other, the scaling tool 5 of the present invention can perform a 360-degree all-round reduction on the original annotation line 211, as Figure 16B shown (211 → 211').

[0068] In summary, in this embodiment, after the user sets the scaling pattern 51, the user can click on the pattern of the scaling tool with the cursor to cause all or part of the line segments of the annotation line to be enlarged or reduced in a certain proportion to the shape of the original annotation line, and the proportion of the enlargement or reduction depends, for example, on the number of clicks. In addition, since the scaling tool 5 of the present invention can arbitrarily change the enlargement or reduction function, the user can conveniently and quickly correct the shapes of various annotation lines 211. If the user uses the scaling tool 5 in combination with the above deformation tool 4, the annotation line can be corrected into a more accurate annotation line more quickly, thereby achieving the effect of improving the accuracy of treatment.

[0069] In addition, in the present invention, although another device of a medical image editor is provided, and the medical image editor includes a scaling tool, since the related description is substantially the same as that of the foregoing scaling tool 5, it is not necessary to repeat it, and the detailed description thereof is omitted. In addition, it should be particularly noted that the medical image editor of the present invention can be set in a general medical image browser.

[0070] The above is only illustrative and not restrictive. Any equivalent modification or change made without departing from the spirit and scope of the present invention shall be included in the scope of the appended claims.
