Congenital heart defect is the most common congenital anatomical malformation of the fetus, and it is also one of the malformations that are most easily missed in prenatal ultrasound examination. Ultrasound imaging technology is currently the most commonly used method of fetal heart examination in clinical practice and plays an important role in the diagnosis and screening of congenital heart disease. With the continuous development of computer science and technology and the advent of electronic matrix probe, three-dimensional ultrasound imaging technology becoming a crucial technique in prenatal screening and diagnosis of congenital heart disease. In this paper, we summarize the recent advances in the application of electronic matrix probe correlation three-dimensional ultrasound imaging technology in fetal heart.
