Example Embodiment

[0062] Example 1:

[0063] A pleural line identification method based on lung ultrasound, comprising the following steps:

[0064] S1. Obtain an ultrasound video of the lung area, and select k frames of ultrasound images in the ultrasound video, k>1;

[0065] During diagnosis, an ultrasound machine will be used to collect raw video data, and then preprocess it to remove irrelevant pictures and segments to obtain an ultrasound video. The main picture in the ultrasound video is the lung area. Therefore, in each frame of the ultrasound video The positions of the pleural line areas in the images are basically the same, with minimal changes, and they are basically in a linear area, which can be understood by relevant practitioners, and will not be repeated here. As in this example, an ultrasound machine is used to obtain ultrasound videos of the lung area with an ultrasound probe, and it is ensured that there is no large fluctuation in the pleural line in the ultrasound videos. Al...

[0094] Example 2:

[0095] A pleural line identification system based on lung ultrasound, comprising:

[0096] The image acquisition module is used to acquire the ultrasound video of the lung area, and select k frames of ultrasound images in the ultrasound video, k>1;

[0097] The image preprocessing module is used to perform grayscale processing on each ultrasound image to obtain a grayscale image of each ultrasound image;

[0098] The single image processing module is used for binarizing each grayscale image to obtain a binarized image of each ultrasound image, and performing pleural line positioning operation on each binarized image;

[0099] The image fusion module is used to fuse the k binarized images after the pleural line localization operation to obtain a fusion image, and perform the global pleural line localization operation on the fusion image to obtain the pleural line area of ​​the lung area in the fusion image.

[0100] Among them, the image preprocessing module...

Abstract

The invention relates to a pleural line identification method and system based on lung ultrasound, and the method comprises the following steps: obtaining an ultrasound video of a lung region, and selecting k frames of ultrasound images kgt from the ultrasound video; 1; performing graying processing on each ultrasonic image to obtain a grey-scale map of each ultrasonic image; performing binarization processing on each grey-scale image to obtain a binarized image of each ultrasonic image, and performing pleura line positioning operation on each binarized image; and fusing the k binary images after completing the pleural line positioning operation to obtain a fused image, and carrying out global pleural line positioning operation on the fused image to obtain a pleural line region of the lung region in the fused image. Compared with the prior art, the method has the advantages that the multiple images are overlapped after the pleural line areas are recognized respectively, the pleural line areas of the video can be recognized more completely, and the influence of pleural line position floating caused by lung sliding is reduced.

Description

technical field [0001] The present invention relates to the technical field of pleural line identification, in particular to a lung ultrasound-based pleural line identification method and system. Background technique [0002] The pleura is the thin, smooth serous membrane that lines the inside of the chest wall and the surface of the lungs. In ultrasound detection, the strong echo reflection formed by the difference in acoustic impedance between the pleura and the lung surface interface appears smooth, clear, and regular linear strong echo under ultrasound, which is called the pleural line. During normal respiratory movement, the visceral pleura and the parietal pleura move relative to each other. At this time, a horizontal sliding sensation can be observed from the pleural line, which is called pleural sliding sign. [0003] The pleural line plays an important role in lung ultrasound. It is not only the interface between the chest wall and the lungs, but also related to th...
