Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of image processing, in particular to a method and device for displaying lesions in a wide-angle fundus image, a storage medium and an electronic device. BACKGROUND

[0002] Since the field of view of a wide-angle fundus image is large, the lesions in the fundus are small and there are dozens of types of visible lesions. When the number of lesion types is too large, doctors cannot determine the classification and distribution of each lesion by naked eye. At present, some methods for representing lesions mark various lesions on the original image with different colors, and some output the type of lesion "visible" or "not visible". However, since the lesions are very small and multiple lesions may overlap each other, the existing lesion display method cannot meet the needs of clinical diagnosis. Moreover, since the output report is generally A4 size, the lesion annotation image presented after the report result is output is small and cannot clearly and comprehensively know the distribution of a single type of lesion.

[0003] Therefore, how to provide a technical solution for displaying lesions in a wide-angle fundus image that is easy to identify has become a technical problem to be solved. SUMMARY

[0038] The technical solutions of some embodiments of this application will now be described with reference to the accompanying drawings.

[0039] It should be noted that similar reference numerals and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures. Furthermore, in the description of this application, terms such as "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0040] In related technologies, different colors are usually used to mark lesions on wide-angle fundus images. However, because the lesions are small and may overlap, it is impossible to clearly know the distribution of a single type of lesion, whether by direct visual inspection or by viewing through a printed report, and thus cannot provide a reliable basis for doctors' diagnosis.

[0041] In view of this, some embodiments of this application provide a method for displaying lesions in wide-angle fundus images. The visualization results obtained by this method can include the specific distribution of the lesions in a preset area in the fundus image. By displaying the visualization results, medical personnel can intuitively and clearly understand the location and distribution of the lesions, providing ophthalmologists and patients with an efficient and accurate diagnostic and treatment auxiliary tool. Fundus images captured by fundus cameras with a field of view greater than 200° are generally called wide-angle fundus images. Because the intraocular angle of a single image can reach 200°, it can cover more than 80% of the retinal area and is also called ultra-wide-angle fundus images. The method disclosed in this application can be applied to ordinary fundus images, such as 45° fundus images, 60° fundus images, 80° fundus images, 120° fundus images, and 150° fundus images, and is especially suitable for wide-angle fundus images and ultra-wide-angle fundus images with a field of view greater than 200°. It is understood that fundus features or changes other than basic features (optic disc, macula, blood vessels) in fundus images can be referred to as lesions or abnormalities. This is just a way of describing them and should not be used to limit the scope of protection of this application. All display of abnormal fundus features is applicable to the display method of this application.

[0042] The following is in conjunction with the appendix Figure 1 The overall structure of a system for displaying lesions in wide-angle fundus images provided by some embodiments of this application is illustrated by way of example.

[0043] like Figure 1As shown, some embodiments of this application provide a system for displaying lesions in wide-angle fundus images. This system may include a terminal 200. A user can select a fundus image to be displayed on the terminal 200; the terminal 200 analyzes and processes the fundus image to generate and display a visualization of the lesion for the user 100 to view.

[0044] In some embodiments of this application, the terminal 200 can be a mobile terminal or a non-portable computer terminal, and the embodiments of this application are not specifically limited here.

[0045] The following is in conjunction with the appendix Figure 2 The present application provides an exemplary embodiment of the process by which a terminal 200 displays lesions in a wide-angle fundus image.

[0046] Please see the appendix Figure 2 , Figure 2 This application provides a flowchart of a method for displaying lesions in a wide-angle fundus image, according to some embodiments. The method may include: S210, obtaining a visualization result of the lesion corresponding to the fundus image, wherein the visualization result includes the distribution location of the lesion in a preset region of the fundus image; the preset region is determined by fundus features of the fundus image. S220, displaying the visualization result of the lesion.

[0047] For example, in some embodiments of this application, terminal 200 can acquire and display lesion visualization results that match fundus images. The lesion visualization results include the specific distribution location of the lesions, so that medical personnel can intuitively obtain the lesion distribution.

[0048] The following is in conjunction with the appendix Figure 3 The specific implementation process of S210 is illustrated by example.

[0049] S211, Obtain fundus features and lesion feature parameters of fundus image, wherein the fundus features include at least one of: optic disc, macula and fundus feature center.

[0050] For example, in some embodiments of this application, fundus features may include: the optic disc, macula, blood vessels, vascular arches, and the center of the region of interest (ROI) (as a specific example of a fundus feature center). The ROI center can be the center of the fundus region in the fundus image. Lesion feature parameters may include lesion location parameters, lesion length, area, fractal dimension, etc. It is understood that fundus features and lesion feature parameters can be selected according to actual needs, and the embodiments of this application are not limited thereto.

[0051] S212, based on fundus features, construct a coordinate system and determine the preset region.

[0052] For example, in some embodiments of this application, a coordinate system is established with a preset point as the center selected from the fundus features, and a preset area is determined from the surrounding area of ​​the preset point.

[0053] In some embodiments of this application, S212 may include: constructing the coordinate system with any of the fundus features as the origin; and planning the preset region with the origin as the center.

[0054] For example, in some embodiments of this application, a coordinate system is constructed using the center point of the optic disc, the macula, the midpoint of the line connecting the optic disc and the macula, or the center of the region of interest (ROI) as a preset point (i.e., the origin). For example, when the midpoint of the line connecting the optic disc and the macula is used as the origin, a preset region is planned around the preset point. The size of the preset region can be set according to the actual situation of the fundus image, and this embodiment of the application does not impose specific limitations on it.

[0055] S213, using the lesion location parameters in the fundus image, determine the distribution location of the lesion within the preset area, wherein the distribution location includes: the distribution coordinates and / or distribution orientation of the lesion.

[0056] For example, in some embodiments of this application, there may be more than one type of lesion in the fundus image. Based on the positional feature parameters of each lesion in the fundus image (as a specific example of lesion position parameters, such as the boundary position or center position of the lesion), its position coordinates in the coordinate system are calculated (as a specific example of distribution coordinates), and the azimuth angle of the lesion region relative to a preset point is quantified (as a specific example of distribution orientation).

[0057] In some embodiments of this application, S213 may include: dividing the preset region to obtain multiple sub-regions; and determining the distribution location of the lesion by determining the sub-region to which the lesion location parameter belongs.

[0058] For example, in some embodiments of this application, the preset area can be divided into several regions (i.e., multiple sub-regions). By using the location characteristic parameters of each lesion, it can be specifically determined which sub-region the calculated location coordinates belong to, thereby obtaining the distribution of the lesions within the preset area. When dividing into several regions, they can be equally divided, or the division method can be selected according to actual needs; this embodiment of the application does not specifically limit the method.

[0059] In some embodiments of this application, the coordinate system types include: circular coordinate system, annular coordinate system, elliptical coordinate system, conventional two-dimensional square coordinate system, and three-dimensional coordinate system. The shape of the preset region can be circular, annular, elliptical, or polygonal. S213 may include: dividing the preset region according to preset angle values ​​in the coordinate system to obtain multiple sub-regions, wherein the shape of each sub-region is a sector or annular sector.

[0060] In one implementation, when the preset area is circular, a circular lesion display image can be output. Specifically, a clock coordinate system can be established within the preset area (as a concrete example of a circular coordinate system), dividing the preset area into 12 sector regions (i.e., several regions, with a preset angle value of 30°), corresponding to 12 time periods on a clock. Then, based on the positional characteristic parameters of each lesion, the position coordinates of the lesion within the preset area in the clock coordinate system are calculated, and the azimuth angle of the lesion relative to a preset point is determined, i.e., the corresponding clock position. In addition, the area, shape, size, density, and length (i.e., coverage area) of the corresponding lesion region can also be determined.

[0061] In another implementation, when the preset area is circular or annular, a circular or annular coordinate system can also be established. Similarly, taking the optic disc as a preset point in the lesion display diagram and establishing a circular coordinate system as an example, the preset area around the optic disc can be divided into several sector areas according to preset angle values. For example, the preset angle values ​​can be 0.5°, 1°, 5°, 10°, etc. That is to say, the several sector areas can be 1° each, 5° each, or 0.5° each; the preset angle values ​​in this embodiment can be flexibly set. After the several sector areas are divided, the sector area where the lesion's position coordinates are located and its orientation information can be determined through the lesion's positional feature parameters. In addition, when establishing an annular coordinate system, the distance to the lesion can be represented by rings of different diameters.

[0062] In other embodiments, the preset region can also be elliptical, with the coordinates and angles in the elliptical system representing the distribution of lesions; the lesion display diagram can have the same shape as the preset region. The preset region can also be a quadrilateral, hexagon, etc. (as specific examples of polygons). When dividing several regions, the diagonal can be used as the basis, or the preset angle value can be used as the basis. This application embodiment does not make specific limitations here.

[0063] S214, Generate a visualization result of the lesions corresponding to the distribution location and morphology of the lesions within the preset area.

[0064] For example, in some embodiments of this application, the lesion visualization results may include the distribution location and morphology of the lesion in the aforementioned preset region in the fundus image. The distribution location may include at least one of distribution coordinates and distribution orientation.

[0065] In some embodiments of this application, the lesion visualization result includes a lesion display image and / or lesion description text corresponding to the lesion display image; the lesion display image is used to show the distribution location, shape, and distribution of the lesions; the lesion description text includes at least one of the following: the name of the lesion, the number of lesions, the area of ​​the lesion, the coordinates of the lesion, and the orientation of the lesion. The lesion display image can be represented in two dimensions or in three dimensions, and this embodiment of the application does not specifically limit this.

[0066] For example, in some embodiments of this application, taking the clock coordinate system established above as an example, the visualization chart of the lesion display is as follows: Figure 4 As shown, the dark gray area in the image represents the distribution location of the lesions. The lesion description text can be: the lesion distribution range is "1.5 clocks (i.e., 7 o'clock to 8:50, as a specific example of location information)". 1.5 clocks: indicates that the lesion area spans a location range of 1.5 clock hours. 7 o'clock to 8:50: indicates that in a clock coordinate system, the lesion area begins at 7 o'clock and ends near 8:30. The lesion name is a name relevant to the field of fundus lesions; the lesion coordinate information indicates the specific distribution location of the lesion; and the lesion quantity information indicates the number of lesions. The lesion morphology describes the specific shape of the lesion itself, which can be irregular or regular. The lesion area (i.e., area information) can be represented by virtualizing the lesion as points and then using the density of these points. The lesion illustration in this application facilitates doctors in quickly and accurately locating lesions, and is intuitive, clear, and easy to understand.

[0067] In some embodiments of this application, the lesion visualization results include at least one distribution location and / or morphology of at least one lesion; each of the at least one lesion is characterized by a different color.

[0068] For example, in some embodiments of this application, when a lesion may exist in multiple locations, a method can be adopted. Figure 5 or Figure 6 The method shown displays the distribution locations of lesions on a visualization chart (i.e., Figure 5 and Figure 6The visualization chart shows a dark gray fan-shaped area and the morphology of the lesions (not shown in the figure). Doctors can view the direction and distribution of lesions based on the area shown in the visualization chart. Alternatively, corresponding lesion description text can be output for each type of lesion. For a circular coordinate system, the representation method of the visualization chart is the same as that of a clock coordinate system, while the lesion description text uses degrees as the basis for the lesion distribution location. To facilitate doctors' viewing, the visualization chart and lesion description text can be output and displayed together. The specifics can be adjusted according to the actual situation, and this application embodiment does not make specific limitations. The shape of the lesion display chart can be circular, annular, elliptical, or polygonal. It is understood that the shape of the lesion display chart can be selected according to the actual application scenario, and this application embodiment is not limited to this.

[0069] In other embodiments, different types of lesions can be distinguished by color on a single image. That is, different types of lesions can be represented by different colors, such as blue for retinal detachment, yellow for hard exudates, and red for fundus hemorrhage, etc. This application does not make specific limitations here.

[0070] In some embodiments of this application, the coordinate system type includes a ring coordinate system. Specifically, the distribution location of the lesion in the lesion display image is within at least one of multiple ring-shaped sub-regions in the preset region. Each ring-shaped sub-region in the at least one ring-shaped sub-region is used to characterize the distribution direction of the lesion and the distance between the lesion and the center. The multiple ring-shaped sub-regions are obtained by dividing the ring coordinate system based on preset angle values.

[0071] For example, in some embodiments of this application, such as Figure 7 The provided diagram shows the lesions represented in a ring-like pattern. Figure 7 As can be seen, the preset area is divided into multiple annular sector areas (i.e., multiple annular sector sub-regions). From... Figure 7 The lesion display diagram clearly shows which annular fan-shaped areas the lesions are distributed in, clearly demonstrating the location, direction, and distance from the center point of the lesions, making it highly readable.

[0072] The final lesion report output section may include, for example: Figure 8 The table shown includes the names and specific distribution of different lesions. In the table, OD represents the right eye and OS represents the left eye. Figure 8The lesion distribution map shown provides a clear overview: the lesion name is "peripheral retinal degeneration," the number of lesions on the OD side is 5, and their distribution location is indicated by the lesion display map next to the number "5." This lesion display map is circular, with the black fan-shaped area within it representing the lesion's location. This quantitative parameter table allows relevant personnel to directly access information about the lesions, offering good readability.

[0073] In addition to displaying the distribution of lesions in a whole sector area as provided in this application, scatter plots, area plots, radar plots, bubble plots, pie charts, and 3D plots can also be used to present the visualization results of lesions. The embodiments of this application are not limited to these.

[0074] As can be seen from the above embodiments of this application, the lesion visualization results provided by this application can very intuitively express the specific location of lesions in wide-angle fundus images, helping doctors to more accurately understand the condition of the lesion area and make diagnosis and treatment plans accordingly. This method, based on fundus color photographs and clinical information, uses artificial intelligence technology to achieve intelligent diagnosis and severity assessment of wide-angle fundus images, and presents the diagnostic results in an intuitive, clear, and easy-to-understand form, providing ophthalmologists and patients with an efficient and accurate diagnostic and treatment auxiliary tool.
