    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).
