3D ultrasound display using optical tracking

A method for capturing a 3D ultrasound volume from a series of 2D cross-sectional images obtained with a conventional B-mode scanner is presented. Optical tracking of the ultrasound transducer is used to locate the digitized sections within the volume. A simple optical tracking technique, which uses two conventional video cameras and stereopsis, is described, and its freedom-of-motion effects on reconstruction and visualization are discussed.<
