[0002] In the field of clinical medicine, early diagnosis and precise treatment of heart disease are crucial to the patient's prognosis. However, traditional cardiac imaging diagnostic methods often rely on scanning images from a single angle or a single phase, which to a certain extent limits doctors' comprehensive assessment of the heart's structure and functional status. Specifically, a single-angle scan may not be able to capture abnormal changes in certain hidden areas of the heart, while a single-phase image can hardly fully reflect the dynamic changes of the heart during the cardiac cycle;

[0003] In addition, cardiac images are often interfered by a variety of factors during the acquisition process, such as changes in patient position, respiratory movement, equipment noise, etc. These factors may lead to a decline in image quality and affect subsequent feature extraction and abnormality detection. Although modern medical imaging technology has made significant progress, in the diagnosis of complex heart diseases, how to further improve image quality and enhance the accuracy of feature extraction is still a technical problem that needs to be solved urgently;

[0043] Figure 2 This is a system block diagram of the ultrasound imaging-based cardiac abnormality analysis system provided by the present invention. DETAILED DESCRIPTION

[0044] The present invention will be further described below in conjunction with the accompanying drawings and implementation modes.

[0045] Embodiment 1

[0046] like Figure 1 As shown, this embodiment provides a cardiac abnormality analysis method based on ultrasound imaging, comprising the following steps:

[0047] S1. Scan the heart region to obtain a heart image as a main image, and scan the same heart region from different angles to obtain at least one heart image as a secondary image.

[0048] Specifically, the patient's heart area is scanned initially by ultrasound imaging equipment, and the heart image obtained by the initial scan is used as the main image. The same heart area of ​​the initial scan is scanned multiple times from different angles, specifically from the side and oblique angles, to obtain multiple heart images at different angles, and the multiple heart images at different angles are used as secondary images. The main image is used as a reference to provide a basis for subsequent image processing and feature extraction; the secondary image is used as a supplement to help enhance the understanding and analysis of the complex structure of the heart.

[0049] In this embodiment, the patient is suspected of having ventricular wall thickening. The patient's heart area is initially scanned by ultrasonic imaging equipment to obtain a main image. The main image clearly shows the general shape of the ventricle from the front, but the details are not obvious enough. Subsequently, multiple secondary images are obtained by scanning from the left and right sides.

[0050] S2. Performing image registration on the secondary image and the primary image, and performing information compensation on the primary image based on the image registration result to obtain a compensated cardiac image.

[0051] Specifically, the secondary image is spatially aligned with the main image, and based on the registration result, the information in the secondary image is used to compensate for the missing or blurred parts of the main image by using compensation and fusion technology to obtain a compensated cardiac image. Image registration and information compensation can integrate complementary information from different views, improve the overall quality and information content of the image, and lay a more solid foundation for subsequent feature extraction and anomaly detection.

[0052] In this embodiment, due to angle limitation in the main image, the thickened portion of the ventricular wall is not displayed clearly. Through registration and information compensation, the clear thickened area information in the secondary image is used to enhance the display effect of the corresponding area in the main image, making the entire heart image more complete and accurate, and obtaining a compensated heart image.

[0053] S3. Performing image optimization processing on the compensated cardiac image, specifically including denoising, sharpening and contrast enhancement, to obtain a compensated optimized cardiac image.

[0054] Specifically, the compensated cardiac image is denoised to eliminate noise points or blurred areas in the image; sharpening is performed to enhance the edges and details of the image; finally, the contrast is adjusted to make different structures in the image more distinct and easy to distinguish, which can significantly improve the image quality and make the cardiac structure clearer, facilitating subsequent automatic or manual feature extraction and anomaly detection.

[0055] In this embodiment, after image optimization processing, in the compensated heart image, the thickened area that was originally slightly blurred due to noise interference becomes clearer, the edge becomes sharper, and the contrast is enhanced, thereby obtaining a compensated and optimized heart image.

[0056] S4. Extract features from the main image and the compensated optimized heart image respectively, including the geometric shape of the heart structure and blood flow information, to obtain main image features and compensated optimized heart image features.

[0057] Specifically, the Sobel operator in the edge detection algorithm is used to identify the boundary lines in the main image and compensate and optimize the heart image. The image segmentation technology is used to extract the heart contour and mark the heart contour structure. Then, the geometric shape features are extracted from the heart contour structure, including the size of the ventricle and the volume of the atrial chamber. The Doppler imaging technology is used to extract blood flow information features, including blood flow velocity, direction and eddy flow hemodynamic characteristics.

[0058] In this embodiment, the contours of the ventricular wall and the ventricular septum are identified, and the compensated optimized heart image is segmented and marked into contour structures such as the left ventricle, right ventricle and atrium using image segmentation technology, and the geometric shape features such as the size and volume of each contour structure are extracted. At the same time, color Doppler imaging technology is used to extract the blood flow velocity characteristics of the left ventricle.

[0059] S5. Based on the features extracted from the main image and the compensated optimized heart image, a pre-set abnormal analysis model is used to detect and identify the main image and the compensated optimized heart image respectively, and the detection results of the main image and the compensated optimized heart image are output.

[0060] In this embodiment, the abnormal analysis model detects and identifies features in the main image and the compensated optimized heart image, and finds that the left ventricle in the main image is of normal size but has a slightly increased wall thickness, while the compensated optimized heart image shows a slowed blood flow velocity during the left ventricle ejection phase.

[0061] S6. Compare the detection results of the main image and the compensated optimized heart image to obtain a heart abnormality comparison result.

[0062] Specifically, the detection results of the main image and the compensated optimized heart image are compared and analyzed to comprehensively evaluate whether there are abnormalities in the state and function of the heart; based on the comparison results, a final heart abnormality comparison result report is output for the doctor's reference and decision-making. By comparing the detection results of different images, a more comprehensive understanding of the state and functional changes of the heart can be obtained.

[0063] In this embodiment, the final report pointed out that the patient's heart had abnormal conditions of myocardial hypertrophy and heart failure, and further examination and treatment were recommended.

[0064] In the specific implementation process, the step S2 specifically includes the following steps:

[0065] S2.1. Preprocessing the secondary image, specifically including removing artifacts and correcting geometric distortion.

[0066] Specifically, artifacts are removed from the secondary image through filtering, non-cardiac structure interference in the secondary image caused by equipment, patients or environmental factors is eliminated, and the spatial position relationship in the secondary image is adjusted to make it consistent with the actual heart structure.

[0067] S2.2. Use an image registration algorithm to align the secondary image with the primary image to obtain a registration result.

[0068] Specifically, a feature-based registration algorithm is selected to first extract common features in the two images, then calculate the correspondence between these features, and apply a projective transformation model to align the secondary image to the primary image.

[0069] S2.3. According to the registration result, the missing or blurred information in the secondary image is identified, and the information of the primary image is compensated by using compensation and fusion technology to obtain a compensated cardiac image.

[0070] In the specific implementation process, the step S4 specifically includes the following steps:

[0071] S4.1. Use image segmentation technology to extract the heart contour and mark the heart contour structure.

[0072] Specifically, the Sobel operator in the edge detection algorithm is used to identify the boundary lines in the main image and compensate and optimize the heart image, and the threshold segmentation in the image segmentation technology is used to extract the heart contour. At the same time, the noise, breaks or redundant parts of the extracted heart contour are eliminated, including smoothing the contour edges, filling small holes, removing outliers and other operations to obtain a more accurate and complete heart contour.

[0073] S4.2. Based on the marked heart contour structure, extract geometric shape features, including ventricle size and atrial volume.

[0074] Specifically, based on marking the heart contour structure, the pixel counting and distance measurement in the image measurement tool are used to calculate the cross-sectional area, major axis and minor axis length and other parameters of the ventricle; the volume of the atrium is calculated by measuring the area of ​​the atrium on multiple sections and combining it with a polyhedron model.

[0075] S4.3. Use Doppler ultrasound technology to analyze and identify hemodynamic characteristics, including blood flow velocity, direction and eddy flow hemodynamic characteristics.

[0076] Specifically, Doppler ultrasound imaging technology is used to obtain color-coded images of blood flow in the heart, and by measuring the blood flow velocity in different areas of the color-coded image, the ejection velocity and filling velocity of each chamber of the heart are evaluated. Secondly, analyzing the direction of blood flow can reveal whether there are abnormal phenomena such as reflux and vortex in the heart.

[0077] In the specific implementation process, the abnormal analysis model training process preset in step S5 includes:

[0078] Collect historical cardiac image data, specifically including cardiac images of normal hearts and known abnormal states;

[0079] Preprocessing the historical cardiac image data, specifically including cleaning the data and standardizing the image, to obtain cleaned cardiac image data;

[0080] A convolutional neural network was selected as the model architecture, and the cleaned cardiac image data was used as a training set to input into the convolutional neural network model architecture to obtain an abnormality analysis model through training.

[0081] In the specific implementation process, the step S5 specifically includes the following steps:

[0082] S5.1. Input the main image features and the compensated optimized cardiac image features into the abnormality analysis model for detection and recognition, and output the main image detection result and the compensated optimized cardiac image detection result;

[0083] S5.2. Record and store the main image detection results and the compensated optimized heart image detection results.

[0084] In the specific implementation process, the step S6 specifically includes the following steps:

[0085] S6.1. Display the main image detection result and the compensated optimized heart image detection result side by side.

[0086] Specifically, the main image detection results and the compensated optimized heart image detection results are displayed through a report generation tool, and the two detection results contain evaluation information on the heart structure, function, blood flow status, etc.

[0087] S6.2, comparing the consistency of the main image detection result and the compensated optimized cardiac image detection result in abnormality detection to obtain a comparison result;

[0088] S6.3. Generate a cardiac abnormality comparison report based on the comparison analysis results.

[0089] Specifically, the consistency and difference between the main image detection results and the compensated optimized cardiac image detection results in abnormality detection are listed in detail, including the comparison of the location, size, shape and other features of the abnormal area, as well as quantitative indicators of the similarity or difference degree, so as to generate a cardiac abnormality comparison report.
