    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).

    摘要: Three dimensional ultrasonic images are formed by volume rendering using a 3D ultrasonic image data set. The data set may be acquired by rocking, sweeping, fanning or rotating a 2D image plane through the volume being scanned, or by steering beams in different angular directions from a two dimensional array of transducer elements. The polar data is volume rendered to form a 3D image by means of projected raylines which are warped to account for the angular geometry of the acquisition.

    摘要: An ultrasonic diagnostic imaging system acquires 3D data sets of the fetal heart by use of a gating signal synthesized from detected motion of the fetal heart. A sequence of temporally different echo signals are acquired from a location in the anatomy where motion representative of the heart cycle is to be estimated, such as a sample volume in the fetal carotid artery or an M line through the fetal myocardium. A heart cycle signal is synthesized from the detected motion and used to gate the acquisition of fetal heart image data at one or more desired phases of the fetal heart cycle. In an illustrated embodiment 3D data sets are acquired from multiple subvolumes, each over the full fetal heart cycle, then combined to produce a live 3D loop of the beating fetal heart.
