Abstract: A method for identifying a body region in a medical image includes obtaining a medical image including a number of consecutive bio-section images, inputting the medical image into a preset machine learning model to obtain a numerical value for each of the bio-section images corresponding to the body region to which the bio-section image belongs, determining whether the numerical values of the medical image are abnormal, adjusting the numerical values when the numerical values are abnormal, determining the body region corresponding to the numerical values or the adjusted numerical values, and labeling the body region in the medical image and outputting the labeled medical image. The bio-section images are cross-sectional images of a living body.
