  • Publication number: 20240320833
    Abstract: An ultrasonic image quality quantitative evaluation method includes segmenting a focus area aiming at a target ultrasonic image to extract a region of interest and perform a masking operation to acquire an image segmentation result mask; taking the image segmentation result mask as a reference image, and quantitatively comparing the reference image with a corresponding focus area according to a set evaluation standard to acquire a plurality of evaluation result indexes; and inputting the plurality of evaluation result indexes as an image feature into a classifier to acquire a quality quantification result of the focus area of the target ultrasonic image, where the classifier takes the plurality of evaluation result indexes corresponding to a sample image as an input feature, takes an image quality label of the labeled focus area as an output, and acquires the quality quantification result through training based on a set loss function.
