摘要： A system and method for image registration includes tracking (508) a scanner probe in a position along a skin surface of a patient. Image planes corresponding to the position are acquired (510). A three-dimensional volume of a region of interest is reconstructed (512) from the image planes. A search of an image volume is initialized (514) to determine candidate images to register the image volume with the three-dimensional volume by employing pose information of the scanner probe during image plane acquisition, and physical constraints of a pose of the scanner probe. The image volume is registered (522) with the three-dimensional volume.

摘要： In an ultrasound imaging system (UIS), an ultrasound scanning assembly (USC) provides volume data (VD) resulting from a three-dimensional scan of a body (BDY). A feature extractor (FEX) searches for a best match between the volume data (VD) and a geometrical model (GM) of an anatomical entity. The geometrical model (GM) comprises respective segments representing respective anatomic features. Accordingly, the feature extractor (FEX) provides an anatomy-related description (ARD) of the volume data (VD), which identifies respective geometrical locations of respective anatomic features in the volume data (VD). In a preferred embodiment, a slice generator (SLG) generates slices (SX) from the volume data (VD) based on the anatomy-related description (ARD) of the volume data (VD).
