Abstract: Aspects and embodiments of the present invention relate to methods and apparatuses for determining a motion path characterizing the motion of a movable ultrasound probe across a skin surface of a body portion. An optical flow sensor fixedly mounted to the ultrasound probe generates a stream of optical flow data indicative of a two-dimensional movement of the optical flow sensor over the skin surface. A distance sensor fixedly mounted to the ultrasound probe generates distance measurement data indicative of a distance between the distance sensor and the skin surface. The motion path, determined by a pathing model, is based on the optical flow data from an optical flow sensor and the distance measurement data from the distance sensor. Further aspects relate to an ultrasound probe and a method of generating a 3D tomographic image of a body portion.

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.

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.
