摘要：
Methods, systems, and media for determining carotid intima-rnedia thickness are provided. In some embodiments, a method for determining carotid intima-media thickness of a carotid artery is provided, the method comprising: receiving a frame from a plurality of images, wherein each of the plurality of images includes a portion of the carotid artery； receiving a user selection of a location with the frame； setting a region of interest, based on the received user selection； detecting a first border and a second border within the region of interest； applying one or more active contour models to the first border and the second border to generate a smoothed first border and a smoothed second border； and calculating the intima-media thickness based at least in part on the smoothed first border and the second smoothed border.
