Diagnostic ultrasound in the early pregnancy deals with the recognition of normal anatomy and/or the detection of anomalies in very early viable pregnancies. There are clinical situations where the position of the embryo does not allow imaging of the optimal section of a certain organ. This is often the case with the transvaginal approach, where movements of the transducer are limited. Deriving new 2D images by anyplane slicing is an important presentation mode of embryonic 3D ultrasound. Geometric 3D reconstructions can also be helpful for the understanding of the embryonic anatomy. High quality 2D tomograms are the prerequisite of 3D imaging of the tiny embryo and its organs. Such ultrasound tomograms can be achieved by using annular array transducers, which have a thin elevation plane due to symmetric focussing. Examples of multiplane imaging and geometric volume reconstructions in the assessment of the embryonic anatomy will be presented, and the limitations will be discussed.
