Title: Semi-automated segmentation method for 3-dimensional ultrasound

Abstract: The present invention provides a semi-automated method for three-dimensional ultrasound for constructing and displaying 3-D ultrasound images of luminal surfaces of blood vessels. The method comprises acquiring a 3-D ultrasound image of a target vessel and segmenting the luminal surfaces acquired from the 3-D ultrasound image of the target vessel to generate a 3-D ultrasound image of the lumen of the target vessel, wherein an inflating balloon model is used for segmenting the luminal surfaces of the target vessel. The method is useful for diagnostic assessment of bodily vessels as well as provides for therapy planning and as a prognostic indicator.
