ABSTRACT
The technology does not only furnish excellent images, but also enables the preparation of videos of the unborn baby that provide the expert with a new spectrum for fine-tuning the diagnosis while, at the same time, leaving the prospective parents with a lasting impression. All images acquired during the freehand movements of the probe are transmitted via the video signal of the ultrasound unit to an external workstation, which is equipped with a frame grabber. The rotation and translation controls can now be used to demonstrate not only conventional section planes but also oblique planes. Prerequisites for high-quality images of the fetal surface are the presence of a sufficiently large amniotic fluid pocket in front of the structure being imaged and the absence of overlying or adjacent structures, such as the limbs, the umbilical cord, or the placenta. The inversion mode converts anechoic structures into hyperechoic structures.
