Abstract
A method is described for automatically and accurately defining tissue borders within ultrasound imaging. A preferred embodiment described provides for accurately delineating endocardial and epicardial tissue borders during ultrasound imaging of the heart using contrast agents. The inventive method requires first defining a set of threshold values corresponding to various imaging depths and correlated within the image. The invention further uses the set of threshold values and a maximization function to accurately identify the tissue boundaries.
