Abstract: Method and apparatus are described herein for registering an anatomical region with a scanned image of the anatomical region.

Abstract: The invention relates to a method, system and computer program product for registering 3D image data. It comprises (a) receiving a first 3D image and a second 3D image; (b) determining a rendering transform for applying to each of the first 3D image and the second 3D image; (c) applying the rendering transform to the first 3D image to provide a first 2D projection and to the second 3D image to provide a second 2D projection; and (d) determining an elastic registration for mapping locations of the first 2D projection to homologous locations in the second 2D projection.

Abstract: A method of providing an image includes providing volumetric data which includes volume of interest data and volume of context data, and providing a first projection image which corresponds with the volume of interest data. A second projection image showing surfaces of objects in the volume of context data not occluded by objects shown in the first projection image is provided. A modified second projection image by adjusting the intensity and opacity of the second projection image is provided. The first and modified second projection images are combined.

Abstract: A measurement system and method for detecting and tracking the pose of an object displaceable in a coordinate reference frame. In the system and method a visible target pattern is provided on the object. The visible target pattern includes a series of contrast regions for providing at least two feature points. Each of these feature points is located at a juncture of an optically detectable plurality of edges. Each edge in the optically detectable plurality of edges separates different contrast regions. The method and system determine the location of the feature points by first locating the edges using the change in contrast between contrast regions, and then determining junctures of multiple edges. The method and system also involve a stereoscopic digital camera for generating a pair of digital images of the target pattern and a marker template comprising a set of reference characteristics including a relationship between the feature points.
