Abstract :
A method is outlined for generating 3-D ultrasound images of arteries from multiple 2-D images with known spatial coordinates. A magnetic spatial locating device is attached to the ultrasound transducer to track its position. Images are acquired that cover the artery from varying views. The images are digitized and then processed by computer methods to find the arterial wall boundaries. Detected boundaries from sequences of images are then transformed to a common spatial reference point and combined to represent the wall in three dimensions. The method is tested on both a phantom and on human carotid artery
