Abstract

A method of defining a heart region from imaging data is provided. Received imaging data is projected into a first plane. A first threshold is applied to the first plane of data to eliminate data associated with air. A largest first connected component is identified from the first threshold applied data. A first center of mass of the identified largest first connected component is calculated defining a first coordinate and a second coordinate of the heart region. The received imaging data is projected into a second plane which is perpendicular to the first plane. A second threshold is applied to the second plane of data eliminating data associated with air. A largest second connected component is identified from the second threshold applied data. A second center of mass of the identified largest second connected component is calculated to define a third coordinate of the heart region.
