Abstract
A method and an apparatus for generating a combined three-dimensional ultrasound image of a body portion are described. Therein, two ultrasound scans are preformed, using a relative tracking system, specifically an inertial tracking, and two partial volume images are generated therefrom. The first and second volumes have an overlapping volume containing a predetermined anatomical structure. Then, respective anatomical structure position data indicative of the position of the predetermined anatomical structure in the respective partial volume image are identified by image segmentation. Then, an initial spatial relationship between the first and second partial volume images is established, based on the identified first and second anatomical structure position data. Then a fine registration algorithm using the initial spatial relationship as an initial input is carried out; and the partial volume images are combined in the common volume using the fine-registered spatial relationship.
