Figure 4From: Eleven fetal echocardiographic planes using 4-dimensional ultrasound with spatio-temporal image correlation (STIC): a logical approach to fetal heart volume analysis After standardization of fetal position in the STIC volume dataset to place the fetus in the exact dorsal supine position, navigating systematically in the volume usually provides a reproducible image from a corresponded movement. Placing the reference dot at the aortic valve in the five-chamber view in plane A and spin the volume around y-axis 15-30 degrees simultaneously displays the LVOT in plane A and short axis of the great vessels in plane B.Back to article page
