Figure 6: Automatic cardiac axis.

This new feature of FINE allows calculation and depiction of the fetal cardiac axis automatically in the four-chamber view diagnostic plane. Through intelligent navigation technology, the angle is automatically measured between the ventricular septum and a line drawn between the crux and cross-section of the aorta in the four-chamber view (depicted as “Method Ao-Crux-Apex” in the image). In this normal fetal heart, the cardiac axis is 44.2 degrees (normal).
