摘要：
A method for processing a sequence of ultrasound frames for display includes receiving a sequence of intravascular ultrasound (IVUS) frames of a vessel having a lumen, the sequence including a first frame and a second frame； determining one or more texture features for each of one or more regions of the first frame； determining at least one flow feature for each of the one or more regions by comparing the first and second frames； deriving a lumen border for the first frame using the one or more texture features and the at least one flow feature to characterize the one or more regions as within or outside of the lumen of the vessel； and displaying an ultrasound image of the first frame with the lumen border.
