The invention relates to the technical field of digital image processing, in particular to an automatic segmentation method and system for an echocardiogram of the department of cardiology, and the method comprises the steps: collecting an image of the echocardiogram, and obtaining suspected noise pixel points according to the continuous features of pixel points in the image and surrounding pixel points; constructing an initial expansion window of the suspected noise pixel points, and obtaining an organization storage index according to the gray value difference in the initial expansion window; carrying out iterative expansion according to the tissue exponent to obtain a final expansion window of suspected noise pixel points; obtaining a threshold adjustment index according to the change trend of the gray value in the final extension window of the suspected noise pixel point; and according to the threshold adjustment index of the suspected noise pixel point, obtaining an optimal threshold for threshold segmen
