[0033] Embodiments of the present application will be described in detail below. Examples of the embodiments are shown in the accompanying drawings, where the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to explain the present application, and should not be construed as limiting the present application.

[0034] The detection method and device for the boundary of mutually infiltrating substances based on OCT according to the embodiments of the present application will be described below with reference to the accompanying drawings. In view of the problem in the related art mentioned in the above background art that in the OCT imaging method, when identifying the boundary of the mutually infiltrating region in complex substances, there is a lack of effective edge segmentation and quantitative analysis means, resulting in low accuracy in identifying the boundary of the mutually infiltrating region in complex substances, the present application provides a detection method for the boundary of mutually infiltrating substances based on OCT. In this method, an OCT B-Scan image with high resolution can be obtained by performing OCT scanning imaging on the region to be detected for infiltration, and it is decomposed into multiple A-line profiles, and then the category to which each A-line belongs is identified and classified. By mapping the classification results back to the B-Scan image, an obvious regional boundary line is formed, and the classification probability of each A-line is calculated, so as to achieve accurate identification of the edge and quantitative evaluation of the infiltration region, which not only improves the accuracy and reliability of edge detection of complex substances, but also can effectively identify the boundaries that are difficult to detect on the surface. Thus, the problem in the related art that in the OCT imaging method, when identifying the boundary of the mutually infiltrating region in complex substances, there is a lack of effective edge segmentation and quantitative analysis means, resulting in low accuracy in identifying the boundary of the mutually infiltrating region in complex substances is solved.

[0035] Specifically, Figure 1 FIG. is a schematic flow chart of a detection method for the boundary of mutually infiltrating substances based on OCT provided by the embodiments of the present application.

[0036] As Figure 1 shown, the detection method for the boundary of mutually infiltrating substances based on OCT includes the following steps:

[0037] In step S101, OCT scanning imaging is performed on the edge region of the region to be detected for infiltration to obtain an OCT B-Scan image of the tissue to be detected for lesions, and basic information of the region to be analyzed is obtained.

[0038] It can be understood that performing OCT imaging on the edge region of the region to be detected for infiltration to obtain an OCT B-Scan image of this region provides necessary basic data for subsequent edge detection, ensuring the accuracy and reliability of the detection.

[0039] Optionally, in an embodiment of the present application, basic information of the area to be analyzed is obtained, including: collecting depth information of the area to be analyzed; and / or collecting structural information of the area to be analyzed.

[0040] During the actual execution process, when performing OCT scanning imaging, the system will comprehensively scan the area to be analyzed. This process is not just simple image acquisition, but through high-resolution imaging technology, depth information and structural information of the area to be analyzed are obtained. Depth information refers to the longitudinal depth data of tissue layers obtained through OCT technology, which can reveal the hierarchical structure inside the tissue and help understand the relative positions and relationships between different tissues. Performing OCT scanning imaging on the area to be detected to generate OCT B-Scan image data, and obtaining the depth and structural information of the area to be analyzed, providing basic data for subsequent edge detection. Structural information refers to the tissue morphological features reflected in the OCT B-Scan image, including the boundaries, shapes of complex substances, and their mutual relationships with other surrounding substances. These information are crucial for identifying the boundaries of complex substances with unclear boundaries.

[0041] Specifically, through real-time OCT imaging in the embodiment of the present application, real-time optical tomography images of the mutually infiltrating areas that need to be finely identified can be obtained. In this process, not only OCT B-Scan image data can be generated, but also the boundaries of complex substances and their volume capacity information can be identified. The extraction of these information provides strong support for subsequent edge detection and ensures the accuracy of the detection results.

[0042] In the embodiment of the present application, OCT scanning imaging can be performed on the edge area of the detected infiltration area to obtain OCT B-Scan images and related depth and structural information, providing necessary basic data for subsequent edge detection. This process uses high-resolution imaging technology, which can not only capture the hierarchical structure of substances, but also reveal the boundaries and morphological features of substances, thereby effectively identifying the target recognition area of complex substances.

[0043] In step S102, the OCT B-Scan image is decomposed into multiple A-line lines, and the actual category to which each A-line belongs is identified.

[0044] It can be understood that an A-line represents signal information in the longitudinal depth direction and can reflect the hierarchical structure and characteristics of substances. Therefore, decomposing the OCT B-Scan image into multiple A-line lines can analyze the substance structure in the image more meticulously.

[0045] Optionally, in an embodiment of the present application, identifying the actual category to which each A-line belongs includes: performing clustering analysis on each A-line among multiple A-line lines to obtain an analysis result; and determining the actual category to which each A-line belongs according to the analysis result.

[0046] During the actual execution process, clustering analysis is performed on each A-line. This analysis process aims to group A-lines with similar characteristics into the same category through mathematical and statistical methods. The result of the clustering analysis can reveal the similarities and differences between different A-lines, thereby providing a basis for subsequent boundary recognition. The implementation of the clustering analysis is usually based on the digital features of the A-line, and these features may include but are not limited to information such as signal strength, shape, and texture. Through the comprehensive analysis of these features, it is possible to effectively distinguish the A-lines of different substances in complex substances.

[0047] Furthermore, according to the result of the clustering analysis, determine the actual category to which each A-line belongs. This process not only depends on the result of the clustering analysis, but also can combine the experience of relevant personnel to mark each A-line to ensure the accuracy and reliability of the classification, thereby initially distinguishing the boundary of the mutually infiltrating region and laying a foundation for subsequent edge detection and region recognition.

[0048] To further improve the accuracy of the classification, a label set of different substances can be pre-constructed based on the result of the clustering analysis using digital features, and the method for obtaining the labels is as Figure 2 shown. Such a label set can not only help us better understand the characteristics of the target detection substances, but also provide a solid foundation for the subsequent training of the classification model.

[0049] The embodiment of the present application can effectively identify the actual category to which each A-line belongs by decomposing the OCT B-Scan image into multiple A-lines and performing clustering analysis on each A-line. This process utilizes the longitudinal depth signal information of the A-line to carefully analyze the hierarchical structure and characteristics of biological tissues, thereby revealing the similarities and differences between different A-lines and providing an important basis for subsequent boundary recognition. The clustering analysis combines digital features such as signal strength, shape, and texture, and can accurately distinguish different substance categories in complex substances.

[0050] In step S103, map the actual category to which each A-line belongs to the OCT B-Scan image to present the boundary line of different category regions on the OCT B-Scan image.

[0051] During the actual execution process, the A-line category information obtained from the clustering analysis is mapped to the OCT B-Scan image, and the boundaries of different category regions are displayed on the image, thereby forming a clear category boundary effect on the B-Scan image.

[0052] Furthermore, the label set constructed in step S102 is mapped to the original A-lines. By combining the label information with the actual A-line data, it is possible to better identify and quantify the boundaries of the infiltration regions in subsequent analyses.

[0053] In the embodiment of the present application, by mapping the actual category information of each A-line to the OCT B-Scan image, the boundaries of different category regions can be clearly presented, thereby improving the visualization effect of the image and the accuracy of boundary recognition. This method not only optimizes the application of the clustering analysis results but also enhances the ability to identify and quantify the boundaries of the infiltration regions by combining the label information with the actual A-line data.

[0054] In step S104, the classification probability of each A-line is calculated, and based on the classification probability, the quantization evaluation results of edge recognition and the range of the infiltration region are determined.

[0055] Optionally, in an embodiment of the present application, calculating the classification probability of each A-line includes: obtaining the category label of each A-line; correcting the category label of each A-line to obtain the corrected A-line data; and training a classification model using the corrected A-line data to obtain the classification probability of each A-line.

[0056] Specifically, the category label of each A-line in the clustering analysis result is manually corrected, especially for the parts with large deviations, which are modified with emphasis. Through manual correction, more accurate corrected A-line data can be obtained.

[0057] Furthermore, using the corrected A-line data, it is used to train a classification model. Through training, the classification model can learn the feature differences between different categories and can obtain the classification probability of each A-line, as Figure 3 shown, and then based on these probability results, edge recognition and the quantization evaluation of the range of the infiltration region are realized.

[0058] Embodiments of the present application can significantly improve the detection accuracy by calculating the classification probability of each A-line and performing edge recognition and quantitative evaluation of the infiltration area range based on this. The method first obtains the class labels of each A-line and manually corrects the labels with large deviations to obtain more accurate corrected data. Then, using these corrected data to train a classification model, enabling it to effectively learn the feature differences between different classes, and finally output the classification probability of each A-line. This process ensures the reliability of edge recognition and the accurate evaluation of the infiltration area.

[0059] In step S105, based on the quantitative evaluation results, summarize the actual classes of each A-line in the area to be analyzed, and map them onto the en-face image of the area to be analyzed. Combine with the basic information to determine the surface boundary area.

[0060] In the actual execution process, by summarizing the classification results of each A-line in the entire area and mapping them to the en-face image, it is possible to combine depth information to identify the boundary areas where the surface is not obvious, further improving the accuracy and reliability of edge detection.

[0061] Furthermore, according to the en-face image reconstructed by combining the B-Scan and the calculated probability distribution en-face image, map the two images and display them in the same image to more intuitively display the detected edges. For example, Figure 4 As shown, taking the detection of the boundary of the diseased tissue as an example, by setting a threshold, those with a probability less than 1 can be classified as diseased tissue. In this way, the diseased area can be accurately resected, and more normal areas can be retained, which is beneficial to the patient's recovery and reduces functional damage.

[0062] Embodiments of the present application can effectively identify the boundary areas where the surface is not obvious by summarizing the classification results of each A-line in the area to be analyzed and mapping them onto the en-face image, and combining depth information, thereby significantly improving the accuracy and reliability of edge detection. In addition, by mapping and displaying the reconstructed B-Scan en-face image and the calculated probability distribution en-face image, the detected edges can be presented intuitively.

[0063] The detection method for the boundary of mutually infiltrating substances based on OCT according to the embodiments of the present application can perform OCT scanning imaging on the to-be-detected infiltration region, obtain a high-resolution OCT B-Scan image, and decompose it into multiple A-line lines, and then identify and classify the category to which each A-line belongs. By mapping the classification results back to the B-Scan image to form an obvious regional demarcation line and calculating the classification probability of each A-line, accurate identification of the edge and quantitative evaluation of the infiltration region are realized, which not only improves the accuracy and reliability of complex substance edge detection, but also can effectively identify the boundaries that are difficult to detect on the surface.

[0064] Next, a detection device for the boundary of mutually infiltrating substances based on OCT according to the embodiments of the present application will be described with reference to the accompanying drawings.
