Three‐dimensional virtual traveling navigation and three‐dimensional printing models of a normal fetal heart using ultrasonography data

What's already known about this topic? Three‐dimensional (3‐D) virtual and physical models based on magnetic resonance imaging or ultrasonography data have been used to model normal and abnormal fetuses. 3‐D virtual navigation has been used to model fetal cervical teratomas and lower urinary tract obstruction, and it possibly has clinical applications. What does this study add? 3‐D physical models and virtual navigation based on the ultrasonography data of a normal fetal heart.
